Changes in February 9 2012 Edition of the AIM
January 20, 2012 Leave a comment
The FAA has released the basic version of the February 9 2012 edition of the Aeronautical Information Manual. (You can download the PDF version of the new edition here; the web version presumably will appear on the official publication date.)
According to the Explanation of Changes in the new edition, the key revisions include:
c. 4−1−20. Transponder Operation
This change explains that transponders should be turned on prior to moving on the airport surface – as opposed to “as soon as possible.”
d. 4−3−23. Use of Aircraft Lights
This change aligns the AIM guidance on the use of aircraft lights with AC 120-74A.
e. 4−4−3. Clearance Items
This change adds language to inform pilots of what to expect from controllers concerning clearance limits and associated phraseology.
h. 5−5−16. RNAV and RNP Operations
This change provides guidance for the definition of “established” for RNAV and RNP operations. [For a more detailed discussion of this update, see this post here at BruceAir.]
k. 7−1−21. PIREPS Relating to Airframe Icing
This change addresses the change to the icing intensity definitions, quantifiable icing rates, and an updated replacement for current terminology. It would also help satisfy NTSB Safety recommendations A-96-51 and -060.*
TO THE FEDERAL AVIATION ADMINISTRATION: Revise the existing aircraft icing intensity reporting criteria (as defined in the Aeronautical Info Manual (AIM) and other FAA literature) by including nomenclature that is related to specific types of aircraft, and that is in logical agreement with existing Federal Aviation Regulation (FARs).
