4.11.2 Observation of radio faults and accompanying procedures

4.11.2.1 How to observe radio faults

1. You do not get a response to your transmissions, but can listen to ATIS and

other traffic

or

2. You cannot hear anything on your radio

In the first example, there is a fault in the transmitter part of your radio. If

Billund Approach does not respond, check with Billund Tower.

When you have pressed the microphone plug in properly!

In the second example, you must assume that the transmitter part of your radio

is fine.
