If the controller does not receive a readback, he will instruct the pilot to do so. If the

pilot does not understand the message he is expected to request that messages

are repeated or clarified.

A route clearance is not a clearance to enter an active runway or to take off.

The words:

‘TAKE OFF’ are only used when an aircraft is cleared to take-off or
when canceling a take off clearance.

At other times the words:

‘DEPARTURE’ and ‘AIRBOURNE’ are used. ATC route clearances shall
always be read back unless otherwise authorised by the appropriate ATS

authority. Clearances and Readbacks always include the aircraft call sign.

In a readback the last thing you say is your callsign.

The EASA FCL makes particular mention of the need to read back the following

clearances:

• ATC route clearances
• Clearances related to runway in use

• Other clearances such as conditional clearances.

• Data such as runway, altimeter settings, SSR codes etc.
