1. AIM<br />

LESSON 24<br />

THE ILS APPROACH ON LIMITED PANEL<br />

The aim of this exercise is to teach the student how to carry out an ILS approach when one or more<br />

instruments have failed.<br />

DEFINITION<br />

The ILS approach on limited panel is defined as being the series of manoeuvres required to transition<br />

from en-route flight to a landing or a missed approach when one or more of the flight instruments have<br />

failed.<br />

2. WHY THIS LESSON IS BEING TAUGHT<br />

This exercise is taught so that the student will be able to safely carry out an ILS approach with one or<br />

more flight instruments failed.<br />

3. WHAT THE INSTRUCTOR IS TO TEACH (Briefing of 45 min.)<br />

i. Recap on the operation and limitations of the ILS system.<br />

ii. Recap on types of instrument failure and recognition thereof.<br />

iii. Recap on the dangers of flying on limited panel.<br />

iv. Recap on the necessity and method of declaring an emergency.<br />

4. THE AIR EXERCISE<br />

1. THE ILS APPROACH i. The aircraft should be flown so as to provide<br />

plenty of time to become established on the<br />

localiser. Knowledge of the power setting<br />

required for the correct rate of descent will be<br />

invaluable in the event that the A/H is<br />

inoperative. The instructor could consider<br />

failing the A/H and or DI for this exercise.<br />

ii. The instructor should consider having the<br />

student simulate declaring an emergency.<br />

iii. The exercise could be used for more circle to<br />

land practice if required.<br />

The instructor may use the opportunity to have the student fly a missed approach on limited panel but<br />

again it must be pointed out that flying on limited panel is an emergency procedure and the student<br />

must realize that at any time the remaining gyro instruments could fail.<br />

5. CONSIDERATIONS OF AIRMANSHIP AND ENGINE HANDLING<br />

AIRMANSHIP<br />

i. The student must declare an emergency.<br />

ii. The student must maintain a high standard of altitude awareness.<br />

iii. The approach must be planned carefully so as to ensure success on the first attempt.<br />

iv. Weather awareness must be high.<br />

v Fuel awareness must be high.<br />
