-Aircraft is known/believed to be under unlawful control
What are the criteria for the Distress phase?
(Reasonable certainty of danger to a/c exists)
-Additional attempts to establish comms fail
-Fuel onboard considered exhausted
-Info received suggests forced landing likely
-Info received that aircraft has/will make a forced landing
