Not considering pilot reaction time, what factors influence a helicopter's ability to survive high wind gust spreads (from any direction) during takeoff and landing?
I have considered:
- Swash plate delay: assuming an example main rotor spinning at 600RPM, the rotor completes 10 rotations per second. If each control input requires 180 degrees of rotation to take effect, then fastest possible reaction time is an adjustment every 1/20 second.
- Mass of the aircraft: a heavier aircraft will be moved a shorter distance by crosswind gusts. This reduces the likelihood a skid will unintentionally strike the ground during the earliest stages of takeoff or the final stages of landing (1inch to 3ft off the ground), which could result in the gust building under the vehicle and causing a roll.
- Rotor system: rigid and articulating rotor systems are not susceptible to mast bumping.
- How do you rank these factors in order of largest influence on surviving high wind gusts during takeoff?
- Are there other factors I have not considered?
