I hope this means your sim instrutor is now out of a job...
Sounds to me he's applying RR Dart fires where the engine
is embedded in the wing (F27, Viscount). Also one had to be
mindful of a turn due to prop effect (torque etc). The Rolly Rip
Dart IMO was dangerous because of all those bloody magnesium
components.
Pod jet engines are safer, and unless it doesn't blow itself to pieces
the rest of the aircraft structure is quite safe. Fuse mount pins ensure
only the engine will fall off and not take the wing with it.
