The Annual Extra 300L Migration

Each year I fly the Extra 300L between its summer base at Boeing Field (KBFI) in Seattle and its winter home at Boulder City, NV (KBVU).

The usual route takes me from KBFI across the Cascade Mountains for fuel stops at Bend, OR (KBDN) and Yerington, NV (O43), before the last leg to KBVU. Those three legs total about 870 nm, and at a cruise speed of 160 KTAS, require 5.5 to 6.0 hours of flying time.

Here’s a highlight video from the first leg (KBFI-KBDN) in late September.

To see scenes from the entire route, watch this video from the same flight in September 2017.

Aerobatics with Data

Here’s a look at an aerobatic ride with data from a Garmin VIRB Ultra 30 camera’s sensors overlaid. The GPS-based position, speed, and altitude don’t match the information from cockpit instruments precisely, and the sensors sometimes can’t keep up with the dynamics of aerobatics, but the data do give you an idea of how quickly things change during aerobatics. We also had a tailwind of about 6 knots during the landing, so the GPS-derived groundspeed is higher than the indicated airspeed during the approach and landing.

It’s also worth noting that during aerobatic rides I try to fly smoothly and keep the Gs under control. Rides aren’t aerobatic contests or airshows.

To display the data in a video, I first import the video and corresponding data into the free Garmin VIRB Edit program. After choosing the gauges to display, I export the video and do the final editing in Adobe Premiere Elements.

Flying the Extra: Seattle to Las Vegas

Each year around the end of September, I fly the Extra 300L from Boeing Field (KBFI) in Seattle to its winter base at Boulder City, NV (KBVU) outside Las Vegas. The video below shows highlights from the flight this year. Enjoy the dramatic changes in the landscape from the well-watered Puget Sound region to the desolate desert in southern Nevada.

The Extra isn’t designed for long-distance journeys, and I have to make two fuel stops to complete the journey of about 900 nm (1670 km). I usually stop at Bend, OR (KBDN) and Yerrington, NV (O43). The flight itself typically requires 5.5 – 6.0 hours; with the two stops the total block time is usually about 8 hours.

Stalls at “Any Attitude, Any Airspeed”

Every pilot learns that a wing can stall “in any attitude and at any airspeed.”

But it’s difficult to demonstrate that principle in a typical training aircraft. This video of an exercise that I do with my stall/spin/upset recovery students shows the value of training in an aerobatic aircraft.

I fly a basic loop, but at several points during the maneuver, I intentionally increase the angle of attack by pulling back abruptly on the stick. Each time I pull, the angle of attack quickly reaches the critical angle of attack, and the airplane shudders in an accelerated stall, regardless of the airplane’s airspeed or pitch attitude relative to the horizon.

In other words, you can change the airplane’s attitude (and its angle of attack) almost instantly, but changing its flight path requires more time. That difference between the attitude and the flight path is angle of attack, and when that angle exceeds the wing’s critical angle of attack, the wing stalls.

It’s also helpful to remember that a loop is just a vertical turn. The same principle applies when you bank the wings and turn an airplane in the horizontal plane. If you pull back on the yoke or stick during a turn, you increase the angle of attack. Pull back too aggressively, and the wing will reach its critical angle of attack and stall, regardless of the indicated airspeed.

Short Aerobatic Videos

I have collected short excerpts from a recent aerobatic flight near Seattle, WA to demonstrate a few basic aerobatic maneuvers. Each video shows the maneuver first from the left wingtip and then from my perspective in the rear cockpit of the Extra 300L.

Early Summer Aerobatic Ride

Here are highlights from an early summer aerobatic ride in the Extra 300L east of Seattle.

The passenger from Switzerland enjoyed the view of the “Cascade Alps” east of Seattle as we flew through a series of aileron rolls; loops, half-Cuban 8s; big, lazy barrel rolls; slow rolls; hammerheads, and a little inverted flight.
