twin time
The OGP Aircraft Management Guide does not require any multi-engine experience for co-pilots in either over or under 5700kgs MAUW helicopters. It even allows for conversion training to be given if the candidate does not have the requisite 50 hours on type. Somebody is obviously thinking about the future. New types with complex FMSs give even experienced pilots more problems than two engines ever did. A lack of "twin time" shouldn't keep a good man down.
