Aileron Trim

Wed Sep 05, 2001 3:41 pm

OK, everyone uses elevator trims...
But does anyone ever use aileron trims ?

When losing situational awareness, pray Cumulus Granitus isn't nearby !

Very few planes are completely "straight",and most need to be trimmed slightly.
Usually cruise speed trim is used as a datum,and small trim changes will occur when speed is changed.Also flaps and slats extension might change the trim.Most larger planes have aileron trim tabs that can be controlled manually or electrically from the cockpit,while smaller planes have a tab that can be set (or bent) while on the ground.

Another common reason is to compensate for uneven fuel loads. Inaccurate fuel gauges, apu fuel burn, or extended idling of one engine on the ground will give you more fuel in one wing than the other.
