Flight Instructors Training Procedures _revised AIC_x

1. AIM
LESSON 22
THE NDB APPROACH ON LIMITED PANEL
The aim of this exercise is to teach the student how to fly an NDB approach when an instrument failure
has occurred.
DEFINITION
This exercise is defined as being the series of manoeuvres necessary to transition from the minimum
safe altitude to a landing or missed approach when operating the aircraft in IMC with one or more
instruments failed.
2. WHY IT IS BEING TAUGHT
This lesson is taught so that the student will be able to carry out an NDB approach when one or more
instruments have failed. As an example the failure of the vacuum pump will usually result in the failure
of the A/H and the DI. Other failures like a pitot/static system failure will also require special techniques
in order to complete the flight safely.
3. WHAT THE INSTRUCTOR IS TO TEACH
i. The various failures that can occur.
ii. How to recognize these failures.
iii. How to cope with the failures.
iv. How and when to declare an emergency.
v. Recap on how to intercept a QDM/QDR using the parallel method.
vi. Discuss the dangers of flying with instrument failure.
vii. Flying the Circle to Land manoeuvre and the dangers of this manoeuvre.
viii. Explain how the missed approach is flown from a Circle to Land manoeuvre.
4. THE AIR EXERCISE
i.
ii.
INTERCEPTING A QDM/QDR
TURNING
*
i. This is probably best taught using the parallel
method of intercepting a QDM/QDR as the
potential for mistakes through trying to
calculate the required intercept heading
using other methods is larger when the
workload of flying with instrument failures is
considered.
ii. The student should be given sufficient
practice at this task until reasonably
proficient.
i. The student should be given a few turning
exercises on limited panel using a stopwatch.
ii. The student should practice compass turns
at this point. The instructor should remind
the student of ONUS and have him turn onto
appropriate headings until this method of
turning has been mastered
