Rudder trim use (adjustments in flight) for cruise, dogfight and Landing phases

[Hamilton]

Dear friends,

I just bought this module and I have a question about the rudder trim use, I mean after take off, do you keep changing that setting in the various phases of the flight or is it basically the same setting, and during landing phase, what rudder trim setting do you use for landing ?

Thanks!

For take off full right rudder trim, for other phases of flight as required. If you have rudder pedals you don't need to trim much because you can compensate slip with rudder pedals.

With rudder trim you mitigate slip, and slip will depend on power, speed of the plane basically you need to correct trim very often in warbirds.

Slip/turn indicator ofc had to be different then in other planes because British design

You want this upper arrow be in the middle all the time. But i will say that rudder trim is useful only for calm flying, take off, cruise, landing for combat trim won't help much, rudder pedals is the way.

Thank you so much for your answer, yes I have a rudder pedal. So, if I understand correctly, I take off with full Right rudder trim (or less), and after that I adjust according to the phases of the flight, sorry to insist, for landing, what time would you suggest to "zero" the trim.

Thanks again!

@Hamilton "Full right rudder for take off" this is procedure from Spitfire manual,  you can use what ever you like, what fits you best this is just a game. This right rudder trim is part of plane configuration for climb, you use high power and with low speed it require a lot of right rudder, so to make it easier for pilot trim lifts some workload from pilot.

"zero" the trim never happens  , You compensate your slip with rudder pedals or with trim if you want put your foot off from rudder pedals that's it.

@grafspee Thanks a lot sir, last question .  In your case, do you use any rudder trim for landing?

@Hamilton No, only foot work.

I "zero" the slip with whatever rudder trim necessary after extending gear and flaps on downwind leg and slowing down to 120-130, 'cause that's close to approach speed I'm going to have soon on final and it's the last phase when I still have time and altitude to do it.

There's no time, however, to fiddle with trims on base and final, as there are more important things to cope with in these critical phases. As graf said, it's pedals then all the way to touch down.
