Cockpit Layout
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
