Cessna 206 Benefits: - 1,500 lb useful load - Good short field performance - Simple maintenance - Reliable operation - Versatile cargo/passenger configuration - Good fuel efficiency - Parts availability 2. Alternatives to Consider: - Cessna 185 (better short field, less capacity) - Piper Cherokee Six (lower cost, less rugged) - Pilatus PC-6 (more capability, higher cost) #### Airstrip Requirements 1. Basic Grass Strip: - 2,500 ft length - 50 ft width - Basic drainage system - Wind indicator - Basic lighting - Tie-down area 2. Hangar Facility: - Aircraft storage - Basic maintenance area - Parts storage - Flight planning room - Fuel storage - Weather station
