Study Notes
Aircraft Limitations
- Aircraft limitations are physical boundaries that define an aircraft's safe operating envelope.
- Flight Limitations: Limit load factors, maximum speeds, and minimum speeds are all regulated to ensure safe operation.
- Limit Load Factors: The maximum force an aircraft structure can withstand during maneuvers, preventing exceeding structural limits.
- Maximum Speeds:
- VMO / MMO: Maximum Operating Speed / Maximum Operating Mach Number, limits exceeding the design speeds.
- Minimum Speeds:
- VMCG: Minimum Control Speed on the Ground, the minimum speed for safe control during takeoff in the event of an engine failure.
- VMCA: Minimum Control Speed in the Air, the minimum speed to maintain control after an engine failure during takeoff.
- VMCL: Minimum Control Speed During Approach and Landing, the minimum speed to maintain control in case of engine failure during approach and landing.
- VMU: Minimum Unstick Speed, the minimum speed required for the aircraft to lift off during takeoff.
- Stall Speed: The minimum speed at which an aircraft can maintain lift.
- Maximum Structural Weights:
- These weights are determined based on the structural strength of the aircraft.
- MTOW: Maximum Takeoff Weight, the maximum weight the aircraft can take off with.
- MLW: Maximum Landing Weight, the maximum weight the aircraft can land with.
- MZFW: Maximum Zero Fuel Weight, the maximum weight the aircraft can be without fuel.
- MTW: Maximum Taxi Weight, the maximum weight the aircraft can have while on the ground.
- Minimum Structural Weight: This is the minimum weight required for maintaining structural integrity, ensuring safe operation for the aircraft.
- Environmental Envelope: This encompasses factors like temperature, altitude, and atmospheric pressure, all of which affect aircraft performance.
- Engine Limitations: Determined by limitations on thrust and engine temperature.
- Thrust Setting: Limited to ensure engine operation within safe parameters.
- EGT: Engine Exhaust Gas Temperature, kept within limits to prevent overheating.
- Takeoff Thrust Limitations: Regulated to ensure safe takeoff performance.
