Hi community,
I have recently almost done a flight from JFK - MIA on the AA Boeing 787-9 dreamliner. Traffic in Miami was busy so I recieved radar vectors by an IFATC member who did a great job. I was cleared for the ILS 26R and so I engaged APPR at 250knts at 6,000ft as I was still far from the runway. I suddenly, without any input to my device, the aircraft violently pitched upwards to +13,000fpm and the speed dramatically decreased causing autopilot to disengage and eventually leading me to a stall.
Has anyone else been experiencing similar issues on the 787-9 or is this a general bug on all aircraft?
This suggests, among many other things that you weren’t trimmed properly. You want to make sure there is no coloured bar in the trim box - that’s needed for the aircraft to maintain stable flight when engaging APPR.
Also 250kts is far too fast to be engaging APPR. 220kts max - ideally 180-200kts.
Could be the solution. I will continue to fly the 787 and will follow your recommendation and see if the issue vanishes. Haven’t flown in a long time in IF so that’s another issue.
I have experienced this on many other aircraft, and my trim, at the time was set correctly and not showing red or any color other the small Green dot. I was at about 160 knots, at all times this has happened. I first set my Nav Source to “Nav 1”, as I set the Runway of the airport I intend to land at to Nav 1, and then activated approach mode. My altitude was at about 3,000 ft.
My first reaction is that this doesn’t make sense. My assumption was that you were too fast for the APPR to even engage? (I’ll test when I get done with an approach on my device)
