Bulldog_1 Posted November 21, 2018 Posted November 21, 2018 For the Training or Instant Mission VFR Straight-In Airfield Landing. When passing thru 250 knots and when you lower the gear and put the flaps full down with the throttle at idle, the aircraft pitches down 2 degrees then pitches up 12-15 degrees and climbs about 300 feet or more (stalls), unless you push forward (hard) on the stick then a PIO begins. I talked to IRL F-18 pilot Brian "Sunshine" Sinclair and he said that the 2 degree pitch down was normal operation but the 10-15 degree pitch-up was not and that the FCS should correct for 1g level flight. I am able to recover and make a successful landing however I feel that the pitch-up is not a natural flight behavior of the F-18. I can generate a clip but I need to know if you want me to not move the control stick and recover or just let the pitch-up happen.

-Painter- Posted November 21, 2018 Posted November 21, 2018 Happens on takeoff as well - there is still something weird what the FCS is doing in low-speed regimes. Had an ocassion as well after catapult launch when the nose pitched up so hard that I wasn't able to 100% counter that with 100% stick full forward deflection - after the Flaps had been set into Auto or after reaching 250 kts that behaviour goes away. But with Flaps the FCS does not hold the 1 G during some speed-changes. Regards REAPER 31 | Painter [sIGPIC][/sIGPIC]
