  Chapter 6, Section II: Airplane Attitude Instrument Flying › Learning Methods › Establish

  Performance instruments. Figure 6-27. Navigation instruments. Trim Another important step in attitude instrument flying is trimming the aircraft. Trim is utilized to eliminate the need to apply force to the control yoke in order to maintain the desired attitude ... When the aircraft is trimmed appropriately, the pilot is able to relax pressure on the control yoke and momentarily divert attention to another task at hand without deviating from the desired attitude. Trimming the aircraft is very important, and poor…

  causes the main control surface to be deflected to a position that corrects the unbalanced condition of the aircraft. Because the trim tabs use airflow ... function, trim is a function of speed. Any change in speed results in the need to re-trim the aircraft. An aircraft properly trimmed in pitch seeks to return to the original speed before the change. It is very important…

  point where the loss of the vertical component of lift and aerodynamic wing loading prohibits the nose of the aircraft from being raised. Any increase in pitch only tightens the turning radius. The key to successfully performing a steep turn ... instructor can demonstrate how to successfully fly steep turns with and without the use of trim. Once the aircraft is trimmed for the maneuver, accomplishing the maneuver is virtually a hands-off effort. This allows additional time for cross-checking…

  Chapter 6, Section I: Airplane Attitude Instrument Flying › Attitude Indicator › Airplane Trim

  degree of flying skill, which ultimately develops, depends largely upon how well the aviator learns to keep the aircraft trimmed. Airplane Trim An airplane is correctly trimmed when it is maintaining a desired attitude with all control pressures neutralized ... Then, the trim is adjusted so that the aircraft maintains that attitude when flight controls are released. The aircraft is trimmed for coordinated flight by centering the ball of the turn-and-slip indicator. • Moving the rudder trim…

Once the aircraft is trimmed for hands-off flight, the pilot is able to devote more time to monitoring the flight instruments and other aircraft systems ... order to trim the aircraft, apply pressure to the control surface that needs trimming and roll the trim wheel in the direction pressure is being held. Relax the pressure that is being applied to the control surface and monitor…
