5.47 How do you use the FS98 auto throttle?

From FlightSim

There are two different autothrottles. One for the Lear and one for the B737-400. The Lear doesn't need arming and there is no "Take off- Go Around" (TOGA) switch as there is in the B737.

Arming means that the function will occur when the airplane leaves the ground, just as arming the spoilers means that that function will take place as the airplane touches down. TOGA means that the throttle will be gradually advanced on takeoff until the takeoff thrust is achieved. Go around advances the throttle back to takeoff thrust and is used to abort a landing.

There is a "Arming" switch on the B737-400 just to the left of the autopilot master switch. This switch plus the autopilot master switch plus the SPD hold switch must be turned on and a value entered in the IAS/MACH window for the autothrottle to work.

I usually set the IAS/MACH value to 250 kts when lined up for takeoff. With all of the above turned on and a notch or two of flaps deployed, I press the TOGA button and the airplane begins it's takeoff roll. I have 3000 dialed in the ALT window but I don't turn ALT hold on until after takeoff and retracting the gear and flaps. Then I turn on ALT hold and check that a positive Vert. Spd. has been assigned. I can usually start bumping up the speed value at this point to maintain a N1 reading of 90%-96%. There are specific rules for the changeover from IAS to MACH, but I can never remember them. I change over at about 300-350 kts. On descent and landings the autopilot can be used to reduce the throttle as required also. Makes one less thing to ride herd on.

I hope this helps you. Others will probably chime in here with there favorite or prescribed methods. It's your simulator, follow whichever advice that turns you on. Get back here if you have any more trouble.
