DESCENTS AND DESCENDING TURNS
When an airplane enters a descent, it changes its flight- path from level to an inclined plane. It is important that the pilot know the power settings and pitch attitudes that will produce the following conditions of descent.
PARTIAL POWER DESCENT
The normal method of losing altitude is to descend with partial power. This is often termed “cruise” or “enroute” descent. The airspeed and power setting recommended by the airplane manufacturer for prolonged descent should be used. The target descent rate should be 400 – 500 f.p.m. The airspeed may vary from cruise airspeed to that used on the downwind leg of the landing pattern. But the wide range of possible airspeeds should not be interpreted to permit erratic pitch changes. The desired airspeed, pitch attitude, and power combination should be preselected and kept constant.
DESCENT AT MINIMUM SAFE AIRSPEED
A minimum safe airspeed descent is a nose-high, power assisted descent condition principally used for clearing obstacles during a landing approach to a short runway. The airspeed used for this descent condition is recommended by the airplane manufacturer and normally is no greater than 1.3 VSO. Some characteristics of the minimum safe airspeed descent are a steeper than normal descent angle, and the excessive power that may be required to produce acceleration at low airspeed should “mushing” and/or an excessive rate of descent be allowed to develop.
