AT Issues

Recommended Posts

Hi,I'm having some problems with the Auto Throttle on a long haul.The AP Mode Display, does the following:- My AT Toggle Switch is On (Glareshield)- IAS/Mach Indicator on the Glareshield, is blank- SPD, THR, FL CH Off- VNAV On- PFD Shows "SPD"Out of the blue, the aircraft will just increase throttles, pick up speed, and the PFD will show a blank in the AT Display on the PFD.The only way I get get it back:- Disenage AT (Toggle switch off, and on) on the Glareshield- Select FL CH on Glareshield- Select SPD on Glareshield- Push SPD selector knob on the Glareshield- PFD shows "SPD" again, and the AT reduces throttles so that the plane goes back to the commanded speed in the FMC.This has happened about 4 times in a row now, each time I managed to get it back. The last time it happened now... :(Hopefully someone can shed some light.Thanks,Chris
