1. AIM
DEFINITION
EXERCISE 17B
PRECAUTIONARY LANDING
A precautionary landing is one not contemplated before the flight commenced, but where engine
power may be available thus providing the pilot with the opportunity of selecting and inspecting a
suitable landing area before executing a landing.
WHAT THE INSTRUCTOR IS TO TEACH
i. Discuss the aerodynamic principles involved.
ii. The air exercise briefing:
a. Applicable Procedures and check lists.
b. Aircraft handling techniques – Demonstration and Observation.
c. Considerations of airmanship and engine handling.
d. Similarity to previous exercises.
e. De-briefing after flight.
WHY IT IS BEING TAUGHT
To enable the student to safely land the aircraft on possible unprepared surfaces and to achieve this
goal he will have to gain a complete understanding of the theory determining:
i. The aircraft configuration for the precautionary landing.
ii. The principles involved during low flying.
iii. The circuit pattern involved during low flying.
iv. The effect of wind.
v. Selection and inspection of landing area.
vi. Principles relating to a short landing.
HOW THE EXERCISE APPLIES TO FLYING
A precautionary landing may have to be carried out for a number of reasons, the most common being:
i. Shortage of fuel.
ii. Uncertainty of position.
iii. Bad weather.
iv. Poor in-flight navigation.
v. Failing light – no night flying experience or no night flying facilities to destination.
vi. Mechanical defects of engine and airframe.
vii. On board emergencies i.e. passengers critically ill.
2. PRINCIPLES INVOLVED
1. CHOICE OF LANDING AREA
i. Surface condition and obstructions.
ii. Size of area available for landing. Should also be long enough for a possible take-off.
iii. Wind direction and gradient.
