I am beginning to master the pmdg 737 NGX but I do not succeed in landing in manual mode (no wind). At about 10nm I cut the A / T, I go down to V / S = 1000ft / min, manage the flats, and target the speed reference. Then I deactivate the AP and the plane becomes unstable and I can not keep the axis of the track.
I wish to receive advice for a successful manual landing.
Glad your enjoying the PMDG I also have it .It does take plenty of practice on manual control . You could try dissengaging closer in .. In real world pilots normaly dissengage at 500 ft . I would practice this until you nail it every time .
