Final answer:
If more than a certain amount of trim is required, maintenance correction should be made at the next capable station.
Step-by-step explanation:
Aileron trim and rudder trim are used to adjust the balance and control of an aircraft during flight. If more than a certain amount of trim is required, it indicates a potential issue with the aircraft's alignment or aerodynamics, and maintenance correction should be made. The specific amounts vary depending on the aircraft and manufacturer, but generally, if more than 3% of aileron trim or 5% of rudder trim are needed, maintenance correction should be done at the next capable station.
As indicated airspeed increases, the airplane—following the principle of trim—will pitch up to try to slow down to the airspeed for which it is trimmed. You'll have to apply nose-down pressure as speed builds, trimming off the pressure as you go.
