Thanks a lot Chuck, it is a surprise since it isn't often that a developer gives you access before release of a new plane :D

Allow me to correct your correction:

 

SOPs indicate that the rotation speeds I listed are correct. The pilot is expected to rotate at the given VR (Rotation) speeds by himself. The auto-rotate feature is designed as a safety feature and is not meant to be used for normal operation.

 

180 kts is pretty fast for a rotation speed; this leaves you very little time to abort a takeoff if you takeoff like that. The risk associated with that is that this procedure is not adapted for short runway and heavy payload configurations. Allowing the aircraft to go to these speeds may also be a safety hazard in the eventuality that the pilot needs to abort his landing and slam the brakes at high speeds. With high-pressure tyres, they could very well burst since wheel brakes are not designed to be operated at more than 145 kts IIRC.

Regarding the FCS logic, the automatic take-off trim function will activate when your wheel speed exceeds 41kts and start deflecting the horizontal stabiliser for around 8 deg (deflection angle) when reaching 108kts CAS. It can be checked through the FCS page.

Does it also reset roll/yaw trim, or do we have to do that manually?

Ok, I was just going by what Jabber's said. I don't know anything about this plane.

 

Thanks.

yeah 180kts is fast and it makes sense as a backup feature to not blow your gear, but Vr is never used as a decision speed in ref. to a go-no-go. Just nit picking. thanks for the guide!!!

Chuck, as with everyone else in this community your guides are invaluable to me. I was wondering, if they're done, could you post the HOTAS Mapping and Curves pages? Thank you for everything you do for all of us, it's truly a monumental amount of work.
