Study Notes
Aircraft Stability and Balance
- Stability is the ability of an aircraft to return to its original flight attitude after being disturbed.
- Balance is the distribution of weight within the aircraft, ensuring it remains level and controllable.
- The Center of Gravity (CG) is the point where the aircraft's weight is concentrated. It is critical to have a CG within specific limits for stable and controlled flight.
Importance of CG Location
- CG Location: The CG must be within specific limits to ensure the aircraft is stable and controllable.
- Too far forward: Difficult to lift off, pitch up during landing, and could stall.
- Too far aft: Difficulty in controlling pitch, might experience uncontrollable nose-down pitch, and could lead to a spin.
Aircraft Weight and Balance
- Purpose: The weight and balance program aims to ensure all aircraft are properly loaded within specific limits.
- Consequences: Failing to adhere to these limits could lead to dangerous flight characteristics and potentially catastrophic accidents.
Aircraft Weighing
- Reason for Weighing: To determine the aircraft's actual weight and balance.
-
Preparation:
- Empty aircraft including all permanently installed equipment
- Empty fuel tanks
- Empty baggage compartment
- All seats in place
- All removable equipment not normally needed for flight
- Weighing Procedure: The aircraft is weighed at several points, and the data is used to calculate the CG location.
Weight and Balance System
- Importance: It helps maintain the aircraft's stability and balance, ensuring safe flight operations.
- Inaccurate information: It can result in incorrect weight and balance calculations, leading to an unstable and uncontrollable aircraft.
Pilot in Command
- Knowledge: The pilot in command must understand the weight and balance limits of the aircraft. This includes knowing the empty weight, moment, and the allowable CG range for the specific aircraft.
- Responsibility: Pilot in command is responsible for ensuring that the aircraft is properly loaded and balanced before flight.
