Aircraft cannot perform rollon landings under realistic/ideal conditions
Assigned, WishlistPublic

Description

A helicopter (wheeled or skidded) is capable of performing a roll on landing when power does not exist for a safe VMC approach to hoer/ground and space is availiable for roll on landing (near verbatim from my aircrew training manual). In the game, with minimal airspeed (100kph) and minimal Rate of Decent (RoD) (-1 fps), no helicopter is capable of surviving a roll on landing.

I would report that I am now able under the above conditions able to land 2 aircraft without destruction on stratis runway: ghost hawk and a/mh9. The blackfoot goes red on all instruments, while the remaining aircraft simply explode. I would note that the H9 series performed the best, but that is due I think to the extra friction of the skids, as another thread deals with the current limit factor of landing at least the ghost hawk and mh9: Aft cyclic yaws the aircraft to the right.

Upon touchdown, colelctive is reduced to roughly 30% to stop lift and pulled to aft position for aerodynamic braking...its how you stop a rolling helo, not with the breaks. Those are used for parking only. Upon aft cyclic, the mh9 is able to BARELY be kept stable until stopping. The ghost hawk almost invariably yaws, trips on its tailwheel, rolls, and blows up. Please note though that all other aircraft still go solid red if not outright detonate upon landing.

Worldsprayer you are the feedback master. Do you also think that the angle of the rotors on some of the helis is off? Without touching the stick is it normal to go backwards on takeoff when you apply collective?

Not usually. Unless the main rotor assembly is tilted backwards, which is something I've never seen, it should stay right where it is unless pilot input is provided or someone built the damn thing backwards.

I made a ticket on this one I think. The thrust appears to be reversed on the aircraft before collective is applied. Start a helo, release the brakes, and push the cyclic forward....and you'll go backwards. Pull the stick backwards...and you'll go forwards. It's almost like the thrust 0 point is set wrong, and at bottom collective its like its thrusting upwards. That's just a guess though
