• Consider external factors such as wind or turbulence

8. Describe the different types of helicopter fuel systems and their advantages and disadvantages?

Gravity-fed fuel systems

• Pros: Simple design, reliable
• Cons: Can lead to fuel starvation in certain flight conditions

Pump-fed fuel systems

• Pros: More reliable in all flight conditions
• Cons: More complex design, higher maintenance costs

Fuel injection systems

• Pros: Most efficient and reliable
• Cons: Most complex design, highest maintenance costs

9. What are the key safety considerations when operating a helicopter in mountainous terrain?

• Altitude awareness: Monitor altitude and terrain clearance
• Weight and balance: Ensure proper weight distribution for stability
• Wind conditions: Consider wind direction, speed, and turbulence
• Navigation: Use accurate navigation tools and maintain visual references
• Emergency procedures: Be prepared for potential emergencies such as engine failure or loss of control

10. How do you use a helicopter’s flight management system (FMS) to plan and execute a flight?

• Input flight plan data (destination, altitude, route)
• Monitor aircraft position and progress
• Receive weather updates and make adjustments as needed
• Manage fuel consumption and calculate estimated time of arrival
• Communicate with air traffic control and other aircraft
