Pocket Sized Posted October 12, 2016 Posted October 12, 2016 ${1} The video as a whole is interesting if you ignore the constant "Falcon is best" vibe. It goes over the challenges of the high altitude + high subsonic flight regime. The link shows a test flight from the cockpit that demonstrates a dive starting from 43,000 feet. The craft is accelerated to .92 Mach and banked 45+ degrees left and right rapidly. Then the aircraft is accelerated further to Mach .97! (Just to give you an idea, even the F-86 REALLY struggles to get here. The ailerons lock and uncommanded roll is very evident.) They pull out of the dive, spiking the G meter to 2 G's on the way out. (Why doesn't everyone include at least a short description with videos they post?) DCS modules are built up to a spec, not down to a schedule. In order to utilize a system to your advantage, you must know how it works.
Bond 42 Posted October 17, 2016 Posted October 17, 2016 Cool video. I recently did Upset Training and Recovery in the Gulfstream G550 for work.. it was in the sim of course lol. But we did about the same.. Climb FL450, pitch 20 degrees down, full power. Accel to Mach .99, transition to 420 knots. Feeling the aileron buzz, snatch, reverse controls. Was a great experience.

Sounds interesting! I once saw a clip of somebody in what I believe was a business jet violently rolling left and right despite the pilot opposing the motions with ailerons... there was a comment that said something along the lines of "yaw damper failed at FL410, my worst nightmare." Aerodynamics are so weird sometimes :D DCS modules are built up to a spec, not down to a schedule. In order to utilize a system to your advantage, you must know how it works.
probad Posted October 18, 2016 Posted October 18, 2016 or rather its less aerodynamics being weird and more that humans aren't cut out for processing fluid dynamics in their heads!

Aerodynamics are so weird sometimes :D It really was great training seeing what the plane can really do. Sounds like a Dutch roll.. yaw damps are important lol With a failed yaw damp in the G550, we are limited to 260 CAS/.80 Mach and must be below 450.
