Use of IFR GPS on Conventional Approaches

FAA has published an update to the AIM, effective 26 May 2016, and it includes a big change if you have an IFR-approved GPS [i.e., a “suitable navigation system” as defined in AC 20-138 and AIM 1-2-3 (b).]

Now, if you fly a conventional approach based on a VOR or NDB (but not a localizer), you can fly the procedure entirely with the GPS, provided you can monitor (using a separate CDI or a bearing pointer) the VOR or NDB facility specified for the approach.

The new language is in section 1−2−3. Use of Suitable Area Navigation (RNAV) Systems on Conventional Procedures and Routes.

The summary of changes to this AIM update notes that:

This change allows for the use of a suitable RNAV system as a means to navigate on the final approach segment of an instrument approach procedure (IAP) based on a VOR, TACAN, or NDB signal. The underlying NAVAID must be operational and monitored for the final segment course alignment.

The new text in the AIM is in paragraph 5 of AIM 1-2-3:

5. Use of a suitable RNAV system as a means to navigate on the final approach segment of an instrument approach procedure based on a VOR, TACAN or NDB signal, is allowable. The underlying NAVAID must be operational and the NAVAID monitored for final segment course alignment.

This change is the result of a discussion at the Aeronautical Charting Forum in 2014.

Changes in AIM Effective 26 May 2016

FAA has published an update to the AIM, effective 26 May 2016, and it includes several important changes of interest to typical general-aviation pilots:

1−2−3. Use of Suitable Area Navigation (RNAV) Systems on Conventional Procedures
and Routes

This change allows for the use of a suitable RNAV system as a means to navigate on the final approach segment of an instrument approach procedure (IAP) based on a VOR, TACAN, or NDB signal. The underlying NAVAID must be operational and monitored for the final segment course alignment. [For more information about this item, see the detailed discussion here.]

3−2−3. Class B Airspace
This change adds an RNAV Receiver as an option for instrument flight rule (IFR) navigation requirement IAW 91.131 (c)(1).

3−2−6. Class E Airspace

This change updates the definition, vertical limits, and types of Class E airspace. The change more accurately reflects Class E airspace regulatory information in 14 CFR Part 71 and more clearly states that Class E arrival extensions have the same effective times as the airport surface area airspace….

4−3−22. Option Approach
This changes adds verbiage advising pilots to inform air traffic control (ATC) as soon as possible of any delay clearing the runway during their stop−and−go or full stop landing.

5−2−8. Instrument Departure Procedures (DP) − Obstacle Departure Procedures (ODP) and Standard Instrument Departures (SID)
This change adds language advising pilots what to expect when vectored or cleared to deviate off of an SID.

5−4−1. Standard Terminal Arrival (STAR) Procedures
This change adds language advising pilots what to expect when vectored or cleared to deviate off of a STAR. Pilots should consider the STAR cancelled. If the clearance included crossing restrictions, controllers will issue an altitude to maintain. It also adds language advising pilots when to be prepared to resume the procedure. Since all clearances on STARS will not include Descend Via clearances, the word “will” was replaced with “may.”

5−4−7. Instrument Approach Procedures
This change adds a note to provide guidance to pilots regarding what to expect when clearances are issued by ATC to altitudes below those published on IAPs.

Comments on Proposed Rule Changes

The FAA recently proposed several significant changes to regulations that expand the use of aviation training devices, training for the commercial pilot and certified flight instructor certificates, maintaining instrument currency, and other issues of interest to many general aviation pilots and flight instructor.

Below are my comments on some portions of the proposed rules, which I have submitted to the docket.

Use of TAA for Commercial and Flight Instructor Certificates

For all the reasons outlined in the proposal, I support the option to substitute a TAA (as redefined in the proposed rule) for the training and practical tests required for the commercial pilot and certified flight instructor certificates with single-engine-land ratings.

One commenter objects that pilots won’t gain experience “with higher performing engine[s], retractable gear, constant speed propeller, etc.” But most flight schools offering training for those certificates rely on aircraft such as the C172RG or Piper Arrow, which have at most 200-hp engines. These are hardly high-performance aircraft, either as defined by FAA regulation or by their speed, sophisticated avionics and equipment, or handling characteristics. Pilots who want to fly aircraft with retractable landing gear, constant-speed propellers, turbocharged engines, and other characteristics typically associated with high-performance aircraft will still, as a practical matter, require checkouts and operating experience mandated by regulations (e.g., the endorsement required to act as PIC in an aircraft with an engine rated at more than 200 HP), insurance, flight school policies, commercial operator specifications, and common sense (a refreshing concept endorsed in the recent proposal to revise 14 CFR Part 23 aircraft certification rules—viz., “The part 23 regulations should not need to prescribe basic physical principles, sound engineering judgment, and common sense.”).

The checkout required for aircraft like the C172RG or Piper Arrow is hardly a leap from a Skyhawk or Warrior. Instead, it’s a small step, and learning to operate and confirm the configuration of, for example, retractable landing gear, is only a small part of a complete commercial pilot or CFI training syllabus, and that basic training hardly prepares a pilot to fly a truly high-performance “complex” aircraft such as Cirrus SR22 (which has fixed landing gear) or a Beechcraft Bonanza.

Similar examples: (1) Pilots with MEL ratings on their pilot certificates legally can fly any multiengine aircraft that doesn’t require a type rating. But in the real world, they must receive training and gain operating experience in specific makes and models to obtain insurance, fly rental aircraft, or act as PIC in a commercial operation; (2) Regulations require only a single logbook endorsement to fly tailwheel aircraft. But the handling characteristics of tailwheel aircraft vary widely (even among those that don’t have big engines, constant-speed propellers, etc.). Again, insurance, rental policies, and common sense oblige pilots who fly tailwheel aircraft to receive training and gain operating experience in specific makes and models.

Maintaining IFR Currency with ATDs

I applaud the proposed changes that would allow instrument-rated pilots to maintain currency with in any combination of aircraft, FFS, FTD, or ATD without requiring an instructor to be present. The current regulations are a deterrent to pilots who use ATDs. They must parse the rules and carefully review their logbooks to ensure that they have met the arcane requirements for various tasks, time limits, and calendar constraints. Instead of using training devices, today most pilots hop in their aircraft with a safety pilot (not necessarily an instructor) and repeatedly fly the same familiar procedures in their local areas, missing opportunities to practice the important skills of briefing and setting up a variety of DPs, arrivals, and approaches that include such elements as DME arcs and course reversals. They also typically don’t gain experience handling realistic equipment failures, challenging weather, and so forth. As the FAA notes, the proposed changes would encourage pilots to maintain their instrument skills.

My experience as an instructor strongly suggests that it’s the mental, puzzle-solving side of IFR flying that deteriorates most quickly over time. Use of training devices is the most effective, efficient way to hone and maintain those mental skills.

Pilots who want to use a training device at a flight school will still require at least an initial checkout on the equipment to ensure that they can use it effectively. Those checkouts are an opportunity for pilots to work with instructors to deficiencies in both their understanding of IFR flying and specific piloting skills, and those encounters will help instructors to develop relationships with pilots who otherwise might not be receiving training.

Pilots are upgrading aircraft to include sophisticated avionics (even if the panel doesn’t meet the revised definition of a TAA). They are increasingly using tablets and other devices as substitutes for charts and to provide information about weather, traffic, and other details. Allowing pilots wider, creditable use of training devices that include, for example, GPS navigators, will help them develop and maintain the essential skills described in such publications as the Advanced Avionics Handbook and Instrument Procedures Handbook. Using training devices also gives pilots opportunities to practice using new technology and develop good operating procedures.

Definition of ATD

The notice includes a new definition of aviation training device (ATD):

The FAA is now proposing to define ATD in § 61.1 as a training device, other than a full flight simulator or flight training device, that has been evaluated, qualified, and approved by the Administrator.

It’s not clear, however, if the proposed changes would eliminate the basic aviation training device (BATD) and advanced aviation training device (AATD) categories as described in AC 61-136 FAA Approval of Basic Aviation Training Devices (BATD) and Advanced Aviation Training Devices (AATD). The language in various sections of the proposed rules is ambiguous and should be clarified, and AC 61-136 and related policy guidance should be revised to ensure that both FAA and airmen throughout the system have a clear understanding of distinctions among the devices. I understand that for the purposes of FAA approval the existing categories may remain desirable—especially for manufacturers. But FAA inspectors, pilots, and instructors should not be confused about the practical application of ATDs for training and maintaining currency.

FAA Proposes Significant Rule Changes

On May 12, 2016, FAA published Regulatory Relief: Aviation Training Devices; Pilot Certification, Training, and Pilot Schools; and Other Provisions in the Federal Register. The proposed rule includes many significant changes to 14 CFR Parts 61 and 91 of interest to pilot and flight instructors.

 This rulemaking would relieve burdens on pilots seeking to obtain aeronautical experience, training, and certification by increasing the allowed use of aviation training devices. These training devices have proven to be an effective, safe, and affordable means of obtaining pilot experience. This rulemaking also would address changing technologies by accommodating the use of technically advanced airplanes as an alternative to the use of older complex single engine airplanes for the commercial pilot training and testing requirements…Finally, this rulemaking would include changes to some of the provisions established in an August 2009 final rule. These actions are necessary to bring the regulations in line with current needs and activities of the general aviation training community and pilots.

In particular, the changes would:

  • Make it easier to maintain instrument currency using training devices
  • Allow the use of technically advanced aircraft (TAA), not just “complex” (i.e., aircraft with retractable landing gear) for training and practical tests for the commercial pilot and certified flight instructor certificates

For example, one proposed change would allow an instrument-rated pilot to use an approved aviation training device (ATD), flight training device (FTD), or full flight simulator (FFS) to fly approaches and other tasks to maintain IFR currency without having an instructor present.

Currently, pilots who perform instrument recency experience requirements in an aircraft are not required to have an authorized instructor present to observe the time. Rather, the pilot can perform the required tasks in actual instrument conditions or in simulated instrument conditions with a safety pilot on board the aircraft. A pilot who accomplishes instrument recency experience in an FFS, FTD, or ATD, however, must have an authorized instructor present to observe the time and sign the pilot’s logbook. 14 CFR 61.51(g)(4).

In revising § 61.57 in the 2009 final rule to include the option of using ATDs for meeting instrument recency experience, the preamble indicated that the FAA did not intend for an authorized instructor to be present during instrument recency experience performed in an FSTD or an ATD. It stated: “[A] person who is instrument current or is within the second 6-calendar month period * * * need not have a flight instructor or ground instructor present when accomplishing the approaches, holding, and course intercepting/tracking tasks of § 61.57(c)(1)(i), (ii), and (iii) in an approved flight training device or flight simulator.” 74 FR 42500, 42518. In 2010, the FAA issued a legal interpretation  [8] stating that, based on the express language in § 61.51(g)(4), an instructor must be present in order for a pilot to accomplish instrument recency experience in an FSTD or ATD. That interpretation acknowledged, however, that the FAA had indicated in the 2009 preamble some intention to change the requirement but that the change was not reflected in the regulation.

The FAA is proposing to amend § 61.51(g) by revising paragraph (g)(4) and adding a new paragraph (g)(5) to allow a pilot to accomplish instrument recency experience when using an FAA-approved FFS, FTD, or ATD—just as he or she might do when completing instrument recency experience in an aircraft—without an instructor present. Because instrument recency experience is not training, the FAA no longer believes it is necessary to have an instructor present when instrument recency experience is accomplished in an FSTD or ATD. An instrument-rated pilot has demonstrated proficiency during a practical test with an examiner. It can be expensive to hire an instructor to observe a pilot performing the instrument experience requirements solely to verify that the instrument recency experience was performed. [9] As noted above, practice in an ATD has the distinct advantage of pause and review of pilot performance not available in an aircraft.

As with instrument recency experience accomplished in an aircraft, the pilot would continue to be required to verify and document this time in his or her logbook. The FAA is retaining the requirement that an authorized instructor must be present in an FSTD or ATD when a pilot is logging time to meet the requirements of a certificate or rating, for example, under §§ 61.51(g)(4), 61.65 and 61.129.

The FAA proposals would also eliminate much of the confusion about varying time intervals and tasks required when using a training device or simulator to maintain instrument currency.

Currently, under § 61.57(c), to act as pilot in command (PIC) of an aircraft under instrument flight rules (IFR) or in weather conditions less than the minimums prescribed for visual flight rules (VFR), an instrument-rated pilot must accomplish instrument experience (often described as instrument practice, currency or recency) within a certain period preceding the month of the flight.

If a pilot accomplishes the instrument recency experience in an aircraft, FFS, FTD, or a combination, then § 61.57(c)(1)-(2) requires that, within the preceding 6 months, the pilot must have performed: (1) Six instrument approaches; (2) holding procedures and tasks; and (3) intercepting and tracking courses through the use of navigational electronic systems. [10] If a pilot accomplishes instrument experience exclusively in an ATD, then § 61.57(c)(3) requires that, within the preceding two months, the pilot must have performed the same tasks and maneuvers listed previously plus “two unusual attitude recoveries while in descending V ne airspeed condition and two unusual attitude recoveries while in an ascending stall speed condition.” 14 CFR 61.57(c)(3). Section 61.57(c)(3) also requires a minimum of three hours of instrument recency experience when using an ATD, whereas no minimum time requirement applies when using an aircraft, FFS, or FTD to accomplish the instrument experience.

If a pilot accomplishes the instrument recency experience using an ATD in combination with using an FFS or FTD, then the pilot must—when using an ATD—perform the additional tasks but the “look back” period to act as PIC is six months rather than two months. 14 CFR 61.57(c)(5). The FAA stated in 2009 that the more restrictive time limitations and additional tasks were based on the fact that, at the time, ATDs represented new technology.

Since the ATD provisions were added to § 61.57 in the 2009 final rule, the FAA has received numerous inquiries regarding the terms used in the rule and what might be acceptable combinations when using various aircraft or training devices to satisfy the currency requirements. [11]

The FAA is proposing to amend § 61.57(c) to allow pilots to accomplish instrument experience in ATDs at the same 6-month interval allowed for FFSs and FTDs. In addition, the FAA is proposing to no longer require those pilots who opt to use ATDs exclusively to accomplish instrument recency experience to complete a specific number of additional hours of instrument experience or additional tasks (in existing § 61.57(c)(3)) to remain current. As discussed previously, significant improvements in technology for these training devices have made it possible to allow pilots to use ATDs for instrument recency experience at the same frequency and task level as FSTDs. The FAA believes that this proposal would encourage pilots to maintain instrument currency, promote safety by expanding the options to maintain currency, and be cost saving. As proposed, a pilot would be permitted to complete instrument recency experience in any combination of aircraft, FFS, FTD, or ATD.

Pilots training for a commercial pilot certificate with a single-engine-land rating or a certified flight instructor certificate would no longer have to train in a aircraft with retractable landing gear or use such an aircraft on the corresponding practical tests. Instead, FAA proposes to allow the use of technically advanced aircraft (TAA) for those purposes.

Under the current requirements, an applicant for a commercial pilot certificate with airplane category single engine class rating must accomplish 10 hours of flight training in a complex airplane  or in a turbine-powered airplane…In addition, the Commercial Pilot Practical Test Standards for Airplane (as well as the Flight Instructor Practical Test Standards for Airplane) require a pilot to use a complex airplane for takeoff and landing maneuvers and appropriate emergency tasks for the initial practical test for a commercial pilot certificate with an airplane category…

With the prominence of airplanes equipped with glass cockpits (i.e., TAA) in today’s general aviation aircraft fleet, the FAA believes it is appropriate to permit the use of certain TAA to complete the training required in § 61.129(a)(3)(ii) and appendix D to part 141 as well as to meet the requirements of the commercial single engine airplane pilot and flight instructor practical test standards…

This trend toward exclusive production of airplanes with glass cockpits (TAA) is due to an increase in demand for advanced avionics cockpit platforms by general aviation consumers. [39] At the same time, there has been a significant decrease in the production of single engine complex airplanes. [40] The FAA understands the decrease in single engine complex airplane manufacturing is due, at least in part, to newer airframe and power plant technologies that allow for aircraft to achieve higher performance (e.g., airspeed, reduced fuel consumption, etc.) without the manufacturing and maintenance costs associated with a retractable gear system that is characteristic of a complex airplane. Cirrus Aircraft has delivered 5,326 aircraft with this fixed gear configuration as of 2012. [41]

Notwithstanding the previous use of terms such as glass cockpit and electronic flight instrument displays, the FAA is proposing to adopt an updated definition of “technically advanced airplane” in § 61.1 based on the common and essential components of advanced avionics systems equipped on the airplane, including a PFD, MFD and an integrated two axis autopilot. These components would be required in order to ensure the TAA used to meet the aeronautical experience requirements for commercial pilots in § 61.129(a)(3)(ii) and appendix D to part 141, as well as the related practical test standards, as amended, have the necessary level of complexity comparable to the traditional single engine complex airplane.

TAA would be required to include a PFD that is an electronic display integrating all of the following flight instruments together: An airspeed indicator, turn coordinator, attitude indicator, heading indicator, altimeter, and vertical speed indicator. Additionally, an independent MFD must be installed that provides a GPS with moving map navigation system and an integrated two axis autopilot. [44] In general, the pilot interfaces with one or more computers in order to operate, navigate, or communicate. The proposed definition of TAA would apply to permanently-installed equipment and would not apply to any portable electronic device. The FAA recognizes the continuing advancements in aircraft avionics and the need for a pilot to be proficient with modern cockpit equipment and automation. As proposed, the FAA would define the term TAA as an airplane with an electronic PFD and an MFD that includes, at a minimum, a GPS moving map navigation and integrated two-axis autopilot.

In addition to adding a definition of TAA to § 61.1, the FAA is proposing to amend the existing training requirements to permit the use of a TAA instead of a complex or turbine-powered airplane by commercial pilot applicants seeking an airplane category single engine class rating. In addition to the regulatory changes, the FAA would revise the practical test standards for commercial pilot applicants and flight instructors seeking an airplane category single engine class rating.
