Toolkit:Airspace Infringement Prevention/Material for Pilots/Contact with ATC
Best Practice – Contact with ATC
- If Controlled Airspace transit is required, be prepared and call ATC well in advance.
- Use the correct phraseology to obtain the clearance you want without confusion.
- Think about what you are going to say before you press the transmit switch.
- Be aware that ATC may be busy even if the controller isn’t talking on the frequency at that moment.
- Remember that the instruction “Standby” is not a clearance and you should remain outside of Controlled Airspace until a specific clearance is given.
- Calling ATC well in advance (3 to 5 minutes flying time is regarded as the best window for most requests) will give the controller time to assess your request and will minimize your possible delay.
Cost – None
In the EUROCONTROL causal factors statistics, 7% of infringements are down to inadequate clearance. This points to either pilots relying on a clearance and not being given one or a breakdown in the communication process. The use of clear R/T requests using standard phraseology helps to eliminate confusion and EUROCONTROL have published a guide for VFR phraseology in Skybrary.
