SHORT FIELD LANDINGDescriptionMaximum performance landing where the landing area is short or restricted by obstructions. ObjectiveTo teach techniques necessary for a short field landing to avoid obstructions or minimize ground roll. Elements· Clear the area · Choose forced landing area (should be runway) · Configure aircraft for normal approach and begin descent as normal · Select outside references (e.g. runway numbers) · Clear area, then turn to final (≤30° bank) · On final: remaining flaps (C172RG: 30º) when runway is assured, CCGUMPS check · Select aim point (e.g. before runway numbers) · Adjust pitch and power to maintain short field approach speed and relatively steep descent angle of 1.3 VSO or as specified (C172RG: 63 KIAS) · Trim to relieve control pressures · Make sure feet are not on brakes · Insure stabilized approach from 500’ AGL · 10-20’ off ground: reduce throttle to idle · Gradually apply back pressure to pitch for landing attitude: (don’t fly into ground effect, cut through it!) when passing aim point, adjusting pitch for climb attitude just above horizon · Touchdown on main gear at minimum controllable airspeed with little or no float, just above a power-off stall, touchdown at selected point beyond and within 100’ · Maintain pitch attitude for aerodynamic braking · Smoothly relax back pressure to quickly lower nose wheel · Flaps up (simulate, necessary to put more weight on gear) · Heavy braking as required (simulate)
Include a discussion on performance charts and other landing scenarios. Keep one hand on throttle. Discuss steeper than normal approach. Emphasize brakes only after touchdown, but simulated for practice landings. A wider than normal pattern can be used to give time to configure the airplane. Common Errors· Failure to allow enough room on final to set up the approach, necessitating an overly steep approach and high sink rate · Unstabilized approach · Undue delay in initiating glidepath corrections · Too low an airspeed on final resulting in inability to flare properly and landing hard · Too high an airspeed resulting in floating on roundout · Prematurely reducing power to idle on roundout resulting in hard landing · Touchdown with excessive airspeed · Excessive and/or unnecessary braking after touchdown · Failure to maintain directional control ReferencesFAA-H-8083-3A Airplane Flying Handbook p. 8-17 This document is provided as is.
