(2) Do a test flight to find the lateral trim necessary for straight and level flight for all flight
conditions:
NOTE: Use the captains control wheel to determine the trim limits. One unit of aileron trim is
equal to six degrees of control wheel rotation.
NOTE: There are no specific limits or requirements for lateral trim outside of this flight test
profile. It is acceptable at other flight conditions to observe different trim settings from
those specified.

(a) To find the aileron trim necessary during cruise, fly with these conditions:
1) Flight speed: Approximately 0.78 mach.
2) Altitude: 37,000 feet or higher.
3) Fuel load: Balanced in the limit of 150 pounds (68 kilograms).
4) Throttles: Balanced thrust in the limit of 1 percent N1 difference, with autothrottles OFF.
5) Autopilot engaged with in HDG SEL, with the wings level.
(b) Apply rudder trim to get zero heading change.
(c) Disengage the autopilot.
(d) Apply aileron trim to keep the wings level and maintain zero heading change.
(e) Write down the amount and direction of aileron trim necessary to maintain straight and
level flight.
NOTE: This is the trim for the Cruise condition.
(f) To find the aileron trim necessary for low speed cruise, and with the flaps extended, fly with
these conditions:
1) Altitude: Between 10,000 to 17,000 feet.
2) Fuel load: Balanced in the limit of 150 pounds (68 kilograms).
3) Throttles: Balanced thrust in the limit of 1 percent N1 difference, with autothrottles OFF.
4) Autopilot OFF.
(g) Fly at 250 kias, with the flaps retracted.
(h) Apply rudder trim to get zero heading change.
(i) Apply aileron trim to keep the wings level and maintain zero heading change.
(j) Write down the amount and direction of aileron trim necessary to maintain straight and
level flight.
NOTE: This is the trim for the Low Speed.
(k) Change the airspeed to flaps 1 maneuvering speed, and extend the flaps to the 1-unit
position.
(l) Apply aileron trim to keep the wings level and maintain zero heading change.
(m) Apply rudder trim to get zero heading change.
(n) Write down the amount and direction of aileron trim necessary to maintain straight and
level flight.
NOTE: This is the trim for the flaps 1 unit.
(o) Change the airspeed to flaps 15 maneuvering speed, and extend the flaps to the 15-unit
position, and extend the landing gear.
(p) Apply aileron trim to keep the wings level and maintain zero heading change.
(q) Apply rudder trim to get zero heading change.
(r) Write down the amount and direction of aileron trim necessary to maintain straight and
level flight.
NOTE: This is the trim for the flaps 15 units.
(s) Change the airspeed to Vref +5 knots, and extend the flaps to the 40-unit position.
(t) Apply aileron trim to keep the wings level and maintain zero heading change.
(u) Apply rudder trim to get zero heading change.
