The FD is now correct. Further more, like the real aircraft, you can change the style of FD.
We have a mix of RR and GE aircraft. The GE's have autostart and the RR's dont. Big potential for a screw up. At least pulling the start switch out first the Fuel control lever to run keeps things conventional. We start 3&4 and then 2&1 (2 packs off but will start well with all 3 going).

Hi,
originally posted by Rainboe
-What are the limitations of autostart at high altitude airport?
-Why there are such limitations?
- Are there such limitations for a manual start?
- Can a high temperature affect a normal start and autostart?
- Are there special procedures for engine start (normal and autostart) at high/hot (or cold) airport? (can APU start be affected in such airport).
Feedback appreciated.
Thank you.

With BA's 747s, all packs off, start in pairs. Works extremely well, hot starts rare, and handled automatically. Fuel will be cut, motored and restarted. Even if one of the two ignition systems on an engine fails, it will cut fuel, motor and restart with the other. Starting could be a problem at Bogota when you were outside the autostart envelope and above the altitude restriction for autostarting.
