Objective:
To develop the student's accuracy, judgment, planning, technique, and confidence when little or no power is available in an emergency approach and landing.
Elements:
Causes: Any situation which warrants a forced landing i.e. engine failure, electrical failure. partial power loss, system/equipment malfunction, etc NTSB factors that may interfere with a pilot’s ability to act promptly and properly when faced with an emergency:
- Reluctance to accept emergency situation: Do not allow the emergency to paralyze your decision-making; maintain flying speed and choose a suitable landing field.
- Desire to save airpane: There may be times that the airplane will have to be sacrificed so that you and your passengers can walk away.
- Undo concern about getting hurt: Fear is a vital part of self-preservation, but it must not lead to panic. Maintain your composure at all times.
- Maintain positive control of the aircraft.
- Trim for best glide speed, configure the aircraft for minimum drag configuration.
- Since power is no longer available airspeed must be controlled with pitch only.
- Select a suitable emergency landing area. Always be on the lookout!
- Ideal: Airport or a hard packed, long, smooth field with no high obstacles at the approach end.
- Cultivated fields are acceptable if the landing is made parallel to the furrows.
- Roads should be used only as a last resort, there are usually power or phone lines which you may not be aware of, as well as auto traffic.
- The selected area must be within gliding distance
- Determine wind direction:
- Looking at trees, smoke, dust, and nearby lakes.
- Always try to land into the wind, this allows for a lower ground speed and a shorter ground roll.
- Sometimes it may not be preferable to land into the wind such as: Insufficient altitude, Ground obstacles, Distance from field, or the field may be on a hill.
- Head straight for the field.
- Utilize any combination of normal gliding maneuvers.
- If altitude permits determine reason for the malfunction and go through engine restart emergency checklist (if engine failure occurs).
- If over a field and altitude must be lost, execute spirals over the field down to pattern altitude.
- Fly the emergency approach as normal as possible since this is most familiar.
- Techniques to use to compensate for overshooting or undershooting are:
For overshooting:
- Lengthen base leg, if landing area permits.
- Widen base leg by heading slightly away from the field.
- Extend flaps.
- Use a forward slip on final.
For undershooting:
- Delay the use of flaps.
- Shorten base leg.
- Turn toward the field to shorten the final approach.
- When landing is assured, execute landing without power checklist. Make sure that any items that may cause a fire are secured. i.e. ignition, fuel, master switches.
- If altitude permits, verify emergency procedures with the checklist.
- Declare an Emergency
- Dial in 121.5 or appropriate ATC facility on the radio.
- Report an emergency (“Mayday, mayday”) state your position, type of aircraft and number of people on board, problem, and intentions.
- Squack 7700 on the transponder.
Common Errors:
- Failure to recognize the urgency of the emergency.
- Improper airspeed control.
- Poor judgment in the selection of an emergency landing area.
- Failure to estimate the approximate wind speed and direction.
- Failure to fly the most suitable pattern for existing situation.
- Failure to accomplish the appropriate emergency checklist.
- Undershooting or overshooting selected emergency landing area.
