Hello IPACS,
In most cases, the 777 will automatically apply full thrust when (1) the A/T is ARMED (no need to be engaged) and (2) airspeed is low. Can you guys add this feature?
Thank you.
777 stall protection

As far as I know the A/T doesn't apply full thrust but if the A/T is armed it activates the speed mode and tries to maintain the lowest safe airspeed above stall speed. Depending on conditions this could go up to the maximum thrust. But I have to read up on this more before I can implement it.

Hope it can be implemented soon

In real life if a Jet no matter if its small as 737 or large as A380 if a jet falls in stall it will never apply full thrust. At least pilots flying that aircraft will increase thrust so that it just stays above stall speed and then thy pitch down the aircraft to come out of stall. Logic behind this is when you apply full thrust pitch of aircraft increase due to thrust forces which pushes aircraft more towards stall rather than saving it from stall. If you look up some incidents happened like this on internet most pilots made mistake increasing full thrust when they were in stall which made situation more worse. So even if you engage A/T in 777 and it applies full thrust it wont save you from stall. I would like Jet-Pack (IPACS) to implement this feature as i described above that when you apply full thrust in stall aircraft goes more towards stall rather coming out of stall by gaining speed.

Well in the A320 and A380 full thrust is applied before reaching the stall. But these aircraft are augmented by fly by wire, too.

True, I apologize for the oversight, I think the protection initiates at near stall speed (the orange part of the speed tape). This can allow some nose authority and can reduce the likelihood of loss of control due to the pitching up.

Yes '' before reaching stall speed '' they apply full thrust, not when they are actual in stall speeds
