accelerates. Upon reaching the desired level off altitude, continue to trim left rudder
nose down, and allow the aircraft to accelerate towards normal cruise airspeed while
maintaining altitude. Two to three KIAS prior to 150 KIAS, smoothly reduce power
to 650700 ftlbs and retrim the aircraft to maintain level flight.
Not trimming right rudder, nose up for slowing airspeed.
Not switching to normal oxygen.
Initiating turns prior to establishing aircraft in a climb.
Not trimming throughout the ICA.
Not coordinating right rudder with initial power application, resulting in poor heading
Raising the nose in reversals. The nose of the aircraft tends to pitch up as the wings
roll through the wings level attitudeforward pressure is necessary to maintain the
same nose attitude during reversals (if properly trimmed).
Overcorrecting for airspeed using abrupt nose attitude changes.
Attempting to correct for AOB using the bank index as a turn needle and rolling in
the wrong direction. Make bank corrections by initiating roll on the miniature aircraft
and then check the bank index.
Insufficient acceleration trim on level off, resulting in climbing past your altitude.
STRAIGHT AND LEVEL FLIGHT (S&L)
Straight and level flight is a condition in which the aircraft is flown in balanced flight holding a
constant altitude and heading. The T34C can be flown in straight and level flight at varying
airspeeds. During the Basic Instrument Stage, the most common condition, known as normal
cruise, is 150 KIAS.
Your instructor will introduce straight and level flight at normal cruise. As you gain
experience, you will be able to maintain the straight and level attitude of the aircraft while in
instrument flight. At first, however, keeping the aircraft in the straight and level flight attitude
will be a matter of conscientious control adjustment.
For straight and level flight, it is necessary that airspeed, heading, and altitude be
maintained. Again, the power primarily controls the airspeed while maintaining altitude.
Reducing power will cause the airspeed to slow; increasing power will cause the airspeed to
increase. While maintaining a constant power setting, however, lowering the nose will cause the
airspeed to increase and raising the nose will cause the airspeed to decrease with a respective loss
