Study Notes
Aircraft Performance and Weight
- An aircraft's weight directly influences nearly every aspect of its performance.
- The physics behind it: more mass demands additional thrust and lift to become airborne.
Balance of Forces
- An aircraft can be imagined as a balanced scale of forces:
- Gravity pulling down due to weight
- Lift generated by the wings and thrust produced by the engines
- Achieving steady flight requires equilibrium between these forces.
Effect of Weight on Performance
- Heavier aircraft require more runway length to become airborne
- Weight increases takeoff distance: more speed is needed to generate lift, requiring a longer runway
- Weight affects rate of climb: a heavier aircraft ascends more slowly, impacting safety and fuel economy
- Weight influences stall speed: a heavier load increases stall speed, requiring a higher speed to maintain lift
Weight and Balance Calculations
- Critical for performance and safety
- Understanding variables (fuel, cargo, passengers) and how they shift the center of gravity is key to predicting aircraft handling
Pilot's Responsibility in Managing Aircraft Weight
- Maximum Takeoff Weight (MTOW) is critical for structural integrity and performance margins
- Exceeding MTOW compromises aircraft safety and can lead to catastrophic outcomes
- Poor weight distribution can result in an unbalanced aircraft, making control more challenging and potentially dangerous
Takeoff and Climb
- Takeoff is one of the most critical phases of flight
- Heavier aircraft require more power to get airborne, increasing the risk of an obstacle collision
- Weight impacts climbing to cruising altitude, with heavier aircraft climbing more slowly
Consequences of Incorrect Weight Management
- Increased fuel burn and reduced range
- Inability to sustain flight
- Reduced safety and increased risk of accidents
Pre-Flight Checks and Weight Control
- Pilots are responsible for conducting thorough load checks and ensuring accuracy of load sheets
- Correctly managing aircraft weight leads to optimal performance, reducing wear on engines, fuel consumption, and extending aircraft service life
