Throttle reduction and touchdown

Recommended Posts

Hi,

I have noticed 2 things, and I don't know what do you think about it?

I find that when you are not using the ezdok camera you don't really feel the touchdown, I mean I don't really hear a touchdown sound exept the speedbreak deployment.

The second thing is the throttle reduction when you do a landing with the A/T, I find that this throttle reduction is too long, and it supposed to be pretty fast. In my case I have an homemade made throttle and I have to press the reverse handle to accelerate the reduction. ( thing which is not really realistic , I mean press the reverse handle at 30 ft)...

I've never had any problem determining whether the aircraft is actually on the ground or not. You should never land so softly that the aircraft floats.

 

There is a common mis-conception in the FS world that you must touchdown as gently as possible, but this is why aircraft run off the end of runways (see the crash of AF358 - the F/O allowed the aircraft to float, instead of realizing the landing attempt was a bust and calling go-around).

 

In short, you should land the aircraft firmly so the weight on wheels switches operate correctly, and you *know* you are on the ground.

 

Regarding the thrust reduction - autolands ALWAYS use more runway than a manual landing. Furthermore, due to precision of autoland systems, there is a random component in the flare program, so the aircraft doesn't land in the same spot twice, thus distributing the touchdown forces and reducing wear on the runway surface.

 

Best regards,

Robin.
