4.10.1.3 Airport Charts

Before we call TOWER for TAXI, we study the airport chart to know the taxiways

to runway 21, which is the runway in use.

You can see the airport chart for

EKRK here.

We are parked on the Apron.

4.10.1.4 Readability

In some cases, you want to get an assessment of how a station receives the

transmitted signals. Then you perform a radio check. This can be done in an

initial call.

We are now ready to do an initial call with a radio check:

Roskilde TWR OY-CTZ radiocheck on 118.9

OY-CTZ Roskilde TWR, read you 5

What does it mean when he reads us 5?
5 Completely readable
Readability is a measure of how clearly (in
4 Readable
this case) Roskilde TWR receives the
3 Readable but with difficulty

transmission. 2 Readable now and then
1 Unreadable
To the right, you see the readability scale.
