Hi

 

Is there any way to increase the Clearance available time when requesting a IFR clearance at an uncontrolled airfield i.e. "If not off before xx:xx clearance will not be valid" .  This would not normally be a problem as most departure procedures can be carried out before the clearance period is terminated.  However this is a different story when flying the PMDG JS41 together with FS2Crew.  The FS2Crew checklist and procedures take so long after receiving clearance that the clearance is terminated by ATC before I can take off (twice now when lining up on the runway), Radar Contact then annoyingly just terminates.  The only way around this I can see is to request clearance just prior to taxi which is of course not very realistic.

The clearance activation limit is hard coded into RC.

 

A search turned up this RW experience less generous that RC's.

Just get your aircraft prepared before getting your clearance. It is your plan so you can enter most of the data into your navigation equipment.

 

If this is done prior to contacting FSS, ten minutes should be plenty to taxi to the runway and take-off at small airports (should be your runway choice) and then activate the clearance with your present position before entering IMC.

Ok, thanks for the info.
