When a pilot transitions from flying a single engine helicopter to a multi-engine airframe one of the first differences that is apparent is the increased system knowledge that must be retained. What isn't initially apparent is the necessity to develop a new mind set when dealing with engine malfunctions.
The majority of single engine flights in multi-engine helicopters were induced by the pilot securing a powerplant due to a malfunction. The mind set to turn off a running engine can be a very difficult mental block to overcome. The most common statement made by a new multi-engine helicopter pilot is "Why would I turn off an engine that is providing power?". The problem with allowing a malfunctioning engine to continue to operate is the possibility that the malfunctioning engine could take out the good engine.
Pilots have a natural tendency to immediately reduce the collective after an engine failure. In a single engine helicopter this is an imperative reaction to maintain rotor rpm. In a multi-engine helicopter it is important to develop a muscle memory to only slightly lower the collective if the remaining engines parameters are about to exceed their limits. If the collective is lowered immediately after a single engine failure the remaining engine not only has to supply power for continued flight but must now also overcome a descent that the pilot has created.
EuroSafety multi-engine airframe courses not only give the pilots a thorough understanding of the emergency procedures and systems associated with a single engine failure but, through addressing engine failures at various segments of flight, condition a muscle memory in the pilot.
To enhance safety during single engine training and to reduce wear on the aircraft all the surface maneuvers are conducted to a runway environment. This requires the helicopter to be equipped with carbide skid shoes. If the training aircraft is not equipped with these shoes ESI can provide a set, free of charge, during the training event.
