A FLYBE DASH 400 was recently subject to an AAIB monthly report.
In summary the cargo door seal failed resulting in a depressurisation followed by an emergency descent to FL100.
A mayday call was transmitted. Once level at FL100 and it had all calmed down it was downgraded to a PAN call.
Uneventful landing.
My Qs to ATCOs:
1. When ScACC notified EDI approach controller of the incident, what actions do ATC take.
2. When the downgrade to PAN is made, what new actions do ATC take.
3. CAP413 gives an example of cancelling a MAYDAY (light ac restarted the engine : now normal operations.)
I cannot find anything which talks about downgrading from Mayday to PAN.
I would welcome ATCOs views on the merits of downgrading, and how this now impacts upon the ATC function.
