Schweizer Aircraft and Jeppesen have updated the training manuals and materials for the Schweizer 300C and 300CBi. Jeppesen first developed manuals for the type in 1980 when it collaborated on the private/commercial helicopter manual with Hughes, the original owner of the Model 300’s type certificate. A decade ago Schweizer and Jeppesen decided jointly to update the original Hughes curriculum. Separately, Schweizer also announced that it had updated the 300Cbi’s information manual.�
