  • 1

    What is the reason to fly within or following the maximum rotor RPM with power

    To protect the engine and tramsmission

  • 2

    What is the reason for following the operational limitation of the minimum rotor RPM with power on?

    To prevent coning and overpitching

  • 3

    What is the reason for following the operational limitation of maximum rotor RPM with power off?

    To protect the structural limitations of the blades and the rotor hub

  • 4

    What is the reason for following the operational limitation of minimum rotor RPM with power off?

    To retain inertia available, so we can glide instead of fall in the event of an engine failure.

  • 5

    What is the reason for following the operational limitation of the VNE speed with power on?

    To avoid retreating blade stall or compressibility. Also to protect the structural components of the aircraft.

  • 6

    What is the reason for following the operational limitation of VNE with power off?

    To prevent the horizontal stabiliser from exerting an excessive upward force on the tail boom.

  • 7

    What is the reason for following the operational limitation of maximum sideways speed

    For aircraft controllability. There will be more parasite drag with sideways travel, no stabilizers, increased risk of dynamic rollover (if low)

  • 8

    What is the reason for following the operational limitation of maximum rearward speed?

    For aircraft controllability. Also cannot see behind you. AIrcraft is not aerodynamically shaped to travel backwards. Risk of CO2 entering the cockpit.

  • 9

    What is the reason for following the operational limitation of maximum take-off weight?

    To achieve successful take-off. Excess weight reduces performance.

  • 10

    What is the reason for following the operational limit of maximum all up weight (AUW)?

    To prevent structural damage. And limit the reduction in performance due to increased weight.

  • 11

    What is the reason for following the operational limit of “minimum operating weight”?

    To prevent adverse handling characteristics. At weights below minimum, the ROD in autorotation may not be sufficient to maintain a safe rotor RPM.

  • 12

    What is the reason for following the operational limitation of “maximum positive & negative flight load factors”?

    To prevent structural damage and maintain controllability of the aircraft
