You are right, the is running an autopilot to hold the altitude.
But I would exspect the opposite:
The aircraft loose weight
so I can reduce the angle of attack
so speed will increase
If the aircraft is losing weight, to maintain altitude, I think you could:
- trim more nose-down (airspeed increases)
- reduce throttle (airspeed decreases)

That's, what I understand, but with the 737,
N1 = 80,4 % all the time,
AP uses only the elevator-trim,
the a/c looses weight from 3x8400 lb to 3x1000 lb,
but Ground Speed decreases from 450 KT to 400 KT
N1 = 100 $ all the time at 6000 ft
AP disabled
the a/c looses weight from 3x10.000 lb to 3x1.000 lb
but ground speed decreases from 555 KT to 538 KT
I have to trim the nose down from 0.047 to 0.156
the Angle of attack changes from -1.2� to -1.4� ???
(value from HUD)
I do not understand the change of the AOA, may be it is a
wrong value.
