before coming to a possible solution for your problem, I need to ask you some questions:
which aircraft do you fly and whats the load?
which device do you use to run infinite flight and which AP modes are engaged, when you anticipate this behavior?
Why is this important?:
…When using a device like the ipad and while flying with the autopilot in ALT HLD Mode some of us “humans” tend to tilt the ipad a little bit forward, without noticing (happened to me a lot of times). While the AP holds the plane on the path, the device anticipates a steering command, that would lower the nose of the simulated aircraft. As soon, as you disengage the autopilot, even though you do not move the device any further, the nose will drop.
The rest of the story is just a logical consequence:
- Increased sink rate also increases the speed.
- Increased speed + extended flaps increases lift
- A plane, fully configured for landing, flies in a very narrow operational envelope and does not forgive abrupt and heavy inputs easily
Any pilot will try to compensate these effects, but what is the right action?
- ? Fast lifting of the nose to a higher pitch to get the speed down?
-> will get you above the glideslope
- ? extend the spoilers?
-> no good in a fully configured plane, at least well out of operational standards unless your plane has a so called steep approach capability
- ? pull back the throttle?
-> not bad, but do not forget to bring them up again. One does not fly an airliner in idle down the glideslope.
Well, in the end its a combination of inputs that might help:
First of all, easy on the controls! “haste makes waste”
Lift the nose gradually, but not too much, reduce thrust but do not forget about your speed.
Lower the gear if it is not already extended and
Try to stabilize the approach. You still have time.
At 1.000 ft, make the check and be honest to yourself: Were you able to stabilize your approach?
yes? -> continue
no? -> go around
In general, I sometimes recalibrate the device before i start the approach. You need to have 0ft vertical movement and leveled wings
happy landings and if I get your answers, I will refly your situation.
