BASIC INSTRUMENT MANEUVERS<br />
Prior to performing precise instrument flying, one must master some basic instrument skills.<br />
What follows is a short discussion on some key instrument flying skills.<br />
501. AIRSPEED CHANGES<br />
General. Smooth, controlled, deliberate change of airspeed is an integral part of all instrument<br />
flying.<br />
Description. Change of power setting to affect change in airspeed. At the completion of an<br />
airspeed change, power is set to maintain the new airspeed. Aircraft should be trimmed during<br />
airspeed changes and fine tuned at the target airspeed, normally practiced between 150-200<br />
KIAS. The Power-Attitude-Trim (P.A.T.) principle applies.<br />
Procedure. To increase airspeed in straight-and-level flight, advance the Power commensurate<br />
with the airspeed change required beyond the setting required to maintain the new airspeed. As<br />
airspeed increases, lift increases, so there is a climb tendency. Adjust pitch Attitude to maintain<br />
altitude and Trim out control pressures. Approaching target airspeed, reduce power to a setting<br />
estimated to maintain the new airspeed. Reduce airspeed in the same manner, but use an<br />
opposite power schedule. Adjustments to trim will be required almost continually during<br />
airspeed changes. Do not neglect the need for rudder trim. An increase in torque generally<br />
requires right rudder trim. Likewise, a reduction in torque requires left rudder trim. Speed brake<br />
may be used for rapid airspeed reductions. Late speed brake retraction near target airspeed may<br />
result in an overshoot of the targeted airspeed. Trim requirements and the possibility for spatial<br />
disorientation increase with use of the speed brake.<br />
Common Errors.<br />
1. Loss of heading control due to insufficient rudder, and/or rudder trim.<br />
2. Loss of altitude control due to slow crosscheck.<br />
502. CONSTANT AIRSPEED CLIMBS AND DESCENTS<br />
General. Maintain constant airspeed during climb or descent.<br />
Description. Climb or descend at a specific airspeed, normally practiced at 140-200 KIAS. The<br />
Power-Attitude-Trim (P.A.T.) principle applies.<br />
Procedure. To climb, increase Power, raise pitch Attitude to maintain desired airspeed, and<br />
Trim. To descend, reduce Power, lower pitch Attitude to maintain desired airspeed, and re-<br />
Trim. The amount of pitch change varies with airspeed and power setting. Although airspeed is<br />
