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.

For your engine I can not answer, but for a Tay (620 & 650), we give the following minimum times based on oil temperature: < +20 Celcius = 4 minutes, +20 to +30 Celcius = 3 minutes, > +30 celcius = 4 minutes.

Only half a speed-brake
FH: I can only quote an Airbus manual, yet I believe the engine limitations are not airframe dependant:
minimum oil temperature for take-off -10° C
no other information! I seem to recall 3 minutes requirement from start-up to take-off thrust, yet couldn't find it.
