Pilot survey

Balancing should be performed at rotation speeds where there are no resonances. This condition is checked by the pilot run. To perform this test the rotor has to run through the relevant range of rotation speed. If there is no way to control rotation speed you may also coast down rotation.
  • For rotors running at constant speed the pilot survey issues warnings in case of expected problems.
  • For rotors with variable speed the pilot run recommends optimum rotation speeds for balancing.
