Temp for take off
Ok may sound a bit stupid but here it goes..
Ambient conditions is 15mins etc
Question.
You are at the aerodrome with a AWIS/ATIS you can use that temp for take off
Now if your at an aerodrome without one of these you use the temp probe which is fitted into the aircraft yeah?....
My real question I guess is the when your sitting on a hot taxiway/runway which would cause the temp probe to over read by a few degrees
Are you compelled to use that temperature for takeoff purposes or say a temp that you read on short final (airflow over probe) without the hot runway factor.
I'm picking the first one, hoping I'm right?
Any direction towards caps or caos would be helpful.
Thanks
