Aircraft Dimensions



The 300CTM helicopter’s cockpit offers two different configurations. The standard right-hand Pilot-In-Command (PIC) flight control configuration allows for comfortable seating of an instructor and student. With the optional left-hand PIC configuration, the right-hand controls can be removed making it possible to seat a pilot and two passengers.

Paint Options

BASF Glasurit exterior paint is used on all Schweizer 300CTM helicopters. It is one of the most technically advanced paints available and is used by numerous premium automobile companies such as BMW and Mercedes. The Schweizer nine-step paint process assures superior corrosion protection and a durable, yet highly attractive appearance. The 300C helicopter is offered with an all white base coat as standard. Optional paint colors and trim schemes are available upon request.

Safety and Crashworthiness

The 300CTM helicopter’s extraordinary safety record is the result of its exceptional flight safety and crashworthiness characteristics. It is the beneficiary of more than thirty years and 20-million flight hours of commercial and military flight experience. Like its predecessors, the 300C aircraft retains high student margins that even seasoned pilots will appreciate.

Crashworthiness Features

• Energy absorption through plastic deformation• Seating configuration places occupants far from the rotor impingement zone• Unique geometry eliminating tailboom strikes

Safety Features

• Rugged, reliable component design• Stable handling characteristics• Excellent safety record• Rapid throttle response

Mast: rollover protection

Articulated rotor system
