Engine Start At Hight/Hot Airport???
 

Hi,

I have some questions regarding engines start at high/hot airport. After reading some posts in this forum, it seems there are some limitations concerning autostart at high altitude airport.

-Why there are such limitations for autostart? Are there such limitations for a manual start?

- Are there special procedures for engine start (normal and autostart) at high/hot (cold) airport? can APU start be affected in such airport?

-What are the limitations of autostart and normal start at high/hot airport?

Feedback appreciated.Thank you.
Best regards

The answer to your questions lies in one word:

Air

At high altitudes there ain't much of it.

With regard to auto versus manual starts, go to your manuals and see what they say.

If your aircraft uses bleed air to start, you may have to get as much load off of the APU as possible to start one engine and then use a cross bleed configuration to start the other.

Hope this helps.
