GENERAL PROCEDURES
1. If an aircraft is unable to continue the flight in accordance with its ATC clearance, and/or an aircraft is unable to maintain the navigation performance accuracy specified for the airspace, a revised clearance shall be obtained, whenever possible, prior to initiating any action.
2. The radiotelephony distress signal (MAYDAY) or urgency signal (PAN PAN) preferably spoken three times shall be used as appropriate. Subsequent ATC action with respect to that aircraft shall be based on the intentions of the pilot and the overall air traffic situation.

4. Obtaining priority from ATC when weather deviation is required.
(a) When the pilot initiates communications with ATC, rapid response may be obtained by stating "WEATHER DEVIATION REQUIRED" to indicate that priority is desired on the frequency and for ATC response.
(b) The pilot still retains the option of initiating the communications using the urgency call "PAN PAN PAN" to alert all listening parties to a special handling condition which will receive ATC priority for issuance of a clearance or assistance.
Ich staune nur immer wieder, wie sich die Piloten diese ganzen Anweisungen merken können.
