Hello, I have some questions regarding the B-737 and PMDG's 737NGX. 1) when I move the stabilizer trim wheel up/down on my control column/yoke, it appears when viewing the plane from the outside that it is the elevators which are moving up/down and not the stabiliizer. Is this correct? 2) When adjusting the rudder and aileron trim, which control surfaces get manipulated? Is it the tabs on these control surfaces? 3) For planes without auto-throttle, does the crew need to constantly adjust the thrust levers throughout the flight including cruise? Thank you very much in advance for the information. -Monzo "pilot wantabe"

1. Stab trim moves the stabiliser. From behind it looks as if the elevators are moving, but in fact they are just keeping the same position relative to the stabiliser, which is moving. 2. Aileron trim moves the control wheel by shifting the neutral (zero force) position in the aileron feel and centring unit. The lateral control surfaces follow as if the pilot had moved the wheel. Rudder trim moves the rudder pedals, again by moving the zero force position. The tabs on aileron move in the opposite direction to the aileron to reduce control forces. There's no tab on the rudder. 3. Without A/T the crew don't need to constantly adjust power in cruise, just every now and then as speed increases due to fuel being burned off. Easy to see for yourself by disengaging the A/T and maintaining cruise Mach over time. During climb the thrust levers will also stay more or less in the same place once climb power is set and still maintain CLB N1 as altitude increases. Kevin Hall
