Citation Roll

[MikeD]

A ballistic aileron roll in slower rolling airplanes should go less than 1g but stay positive throughout the maneuver.

Can the F15 roll from straight & level without any altitude loss?

Easy. As can the -38, F-16, etc.

Can the F15 roll from straight & level without any altitude loss?

Yes. The 38 is even better.

Good write up. Do you have the previous one where Greg Koontz talked about 0g aileron roll?

Yes, the 0g aileron roll is easier said than done for sure. If it's for IAC, a normal aileron roll for me usually gets ~1g....sometimes slightly less on top... The perfect 1g 'corkscrew' aileron roll is hard (for me).... My Barrel rolls usually hit about 3-4g on the down line in the most gentle of pulls. If I remember right from that article, Hoover did a 60 degree nose high entry for his famous corkscrew 1g aileron roll with the tea.

I'm going to go try that with a 414 today:bandit:

The 0g roll is very hard on earth, the 1g one is merely challenging.

Some thoughts from the NTSB on aerobatics in non-aerobatic aircraft.
http://libraryonline.erau.edu/online-full-text/ntsb/aircraft-accident-summaries/AAR94-01S.pdf

"One GP Express first officer told safetyBoard investigators that while he was in training and had not yet been hired by the airline, he had observed the flying pilot perfom two wingovers and an approach to a hammerhead stall in a C-99 on a nonrevene flight from EAR to GRI. Both maneuvers are aerobatic maneuvers and, hence, not permitted to be performed on these aircraft."

"The recorded cockpit discussion clearly reveals that the flying pilot of the accident aircraft performed a prohibited maneuver (apparently a barrel roll) at night and at an altitude insufficient to reasonably assure recovery of the airplane."

"The egregious nature ofthis accident leads the Safety Board to consider the possibility that other pilots operating aircraft certificated for 14 CFR Part 135 operations, in circumstances similar to those of this accident, have considered performing aerobatic maneuvers. While the Safety Board was unable to conclusively determine that the pilots of the repositioning flight had performed aerobatic maneuvers, the conversation recorded on the CVR during the flight, specificaliy the references to “vertical thing” and “aerobatics,” suggested that unauthorized meuvers were conducted. At the very least, the CVR reveals that the pilots displayed immaturity and a lack of professionalism and responsibility about the aircraft with which the airline had entrusted them."

That accident was a big one regarding flight discipline matters, when it happened and the details came out.
