    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.
