Re: Is there a minimum "rest" time for an aircraft?

Which aircraft have pre-start temperature limits? e38 A330 (Trent) and A350 just to name two. 700C EFT limit for starting on the ground. There are temperature limits for engine start. If the EGT temp is over the limit, you can't start it . Isn't that what we motor the engine during start to ensure ...

There is none! You have to be below 100C before moving the fuel lever to run. After that, the applicable start EGT limit will apply. That's it. Again, if you don't see a limit specified; there is none!

Hi thanks for your reply. I'm only hung up on the concept of a resting period for EGT something or other. I understand the upper EGT limit quite well. It's the mystical "no you can't start the engine at that EGT limit because it needs to rest" that has me flummoxed. In my experiences opera...

This is the information in the header of the chart.

The question is: What does the "/" between GNSS / RADAR mean?

GNSS AND RADAR or GNSS OR RADAR?
