Button for rudder trim bias reset

[WildBillKelsoe]

I can't find in keyboard assignments or SAS panel button for rudder SAS trim bias reset. I know I could click on it with mouse left to reset but rather would like to assign a HOTAS function for it. Is it there?

Actually no such button exists in real life for rudder trim, Take Off trim doesn't even do anything with the rudders. The real rotary has an indent do the pilot knows when it's centered.

Ok a little OT, but do you use rudder trim bias in combat or just aim and attack downwind?

[Snoopy]

I never use rudder trim because in the sim it isn't to get it centered with the rotary.

Ok, can you tell if rudder trim should be used on takeoffs and landings and how it is configured for every knot of crosswind?

Rudder trim isn't used for take off or landings. I've never flown an A10 but have lots of time in several commercial airframes.

When both engines are operating, rudder trim is only used to "center the ball" on the inclinometer.

Yaw dampers are what maintains coordinated flight in turns etc, in jet aircraft. Especially those with swept wings.

When I flew the Brasilia, a twin engine turbo prop, we used rudder trim all the time because power changes resulted in aerodynamic changes. Hence any change to the power settings required an immediate rudder trim adjustment to stay coordinated.

In turbojet aircraft, this doesn't really apply. The only time you use rudder trim in large amounts is single-engine operations.

Also, remember trim is only used to relieve control input pressures, not to do the work for you.

Ok why is it included in this simulator? More importantly why included in aircraft in the first place? If its not used in attacks, not used in takeoffs or landings, then what is IT used for??

To trim the aircraft incase of a failed engine or airframe damage.

ok thanks
