The pattern to the emergency landing strip, is a 360 degree overhead approach.
If we consistently practice this maneuver using the same figures and make
adjustments for density altitude and wind, judgment skills will be sharp when the
day comes that we have to do it for real.
During descent, vary turns to lose altitude to arrive at high key on heading –
airspeed and altitude. Remember that we shallow the turn upwind, steepen the
turn downwind, dive into a headwind.
If high at the 90°position, excess altitude can be lost by delaying the final turn,
lowering full flaps (if not previously done), extending speed brakes, and/or
advancing the propeller control lever to full increase rpm (to increase the drag of
the propeller), and slipping on final. The most effective way of losing altitude is
the slip. In case of undershooting, sink rate can be decreased by placing
propeller control lever to full decrease rpm (if not already there), raising flaps to
one-half (above 400 feet), or raising the landing gear. The flaps are the highest
drag item. To prevent the normal tendency to undershoot, the high key must be
established over the intended point of landing 1/3 – 1/2 way down the runway;
the low key must be with 1600-1800 AGL which will appear as a one wing tip
distance abeam the intended point of landing.
