Hi,

 

if I do the ramp start according to the manual, my aircraft accelerates a little despite activating the handbrake/ wheelbrake. At 73% RPM the aircraft flips a few feet.

 

A friend discovered, that this don't happen, if the emergency hydraulic pump is on before the engine starts. But according to the manual, this emergency pump have to be activated later.

 

Is this a bug or a issue in the manual/ ramp start procedure?

 

 

Kind regards,

Fire

Yep, using the parking break.

I think I've only had this happen once; maybe it's dependent on weather? Cooler temperatures should result in more thrust, so maybe the initial surge can be enough to override the parking brake in some conditions?

 

Are you using the DCS World 1.5 beta or 2.0 alpha?

What are you turning on prior to the starting engine? I (literally) just read a post that mentioned this:

 

Thanks Chuck, great work! The checklist from this M2000 manual has the Batt TRN Alt1 and Alt2 all being switched on as the first item. Dassault/mirage2000/manuel-pilote Page 127. I know you must at least have the Batt and TRN on for the parking brake to work as the engine accelerates past idle during start otherwise you lurch forward.

 

This is different to the procedure in the manual which I think assumes a ground power cart is being used. Maybe it makes a difference? I think I pretty much always turn TRN on at the very start.
