Forced Landing: the aircraft is forced to make a landing due to technical problems, medical problems or weather conditions. Landing as soon as possible is a priority, no matter where. A forced landing may be necessary even if the aircraft is still flyable. This can arise to either facilitate emergency medical/police assistance or get the aircraft on the ground before a major system failure occurs which would force a crash landing/ditch situation.
Ground procedures. The emergency procedures to be applied by the ground specialists (e.g. in case of a forced landing) should be specified.
