Jet engine warm-up time
Quick question.
Is there a minimum engine warm-up time on a CFM-56 (B738) before take off?
I'm finding it that I'm taking-off within 2 mins of engine 1 start due short taxy to runway.
My concern is now during winter time the A/C will have been standing static during the night in temps of -5 to -10 celcius, with a departure at 6.30am.
Cheers for the help.
