Hi.
I will explain you the modes: (reference for V3.2.1, see top of it-autoflight.nas to see your version)
ALT HLD: A/P is holding altitude set
ALT CAP: A/P is capturing altitude set
VS: A/P is holding commanded Vertical Speed
FPA: A/P is holding commanded FPA
SPD CLB: A/P is using Pitch to Hold Airspeed set. The minimum clamp is 150fpm. So, if the aircraft is below the target speed, climb will be slow, if above, climb will be high. When at the speed, the A/P is holding the best climb rate for current power setting. If you increase power, aircraft will nose up. So what was your current speed in the video?
SPD DES: same as SPD CLB, except descent instead. Maximum clamp is -150fpm. Below target speed, descent will be fast, above target speed, descent will be slow. When at the speed, the A/P is holding the best descent rate for current power setting.
T/O CLB: Aircraft is holding set V2+10 speed with SPD CLB rules.
G/A CLB: Aircraft is holding the speed set at time of Go Around with SPD CLB rules.
G/S: A/P is following Glideslope
LAND: Glideslope data used for final descent toward runway (<= 100ft)
FLARE: A/P is flaring aircraft (<= 50ft)
ROLLOUT: Aircraft is lower nose, then keeping nose gear on ground after touchdown.
If your turning, you loose lift, and in SPD CLB, the nose will drop, because the speed will reducing. Is normal. But that depends on the plane.
Hope this explain you!
Kind Regards,
Josh
