"No Hands" Helicopter Blade Tracking
The FasTrak day and night optical Blade Tracker as part of a 8500C or
CHAMP™ system, provides blade track and lead/lag data automatically,
without operator interpretation. The FASTRAK is mounted on the fuselage,
oriented upward toward the underside of the rotating blades. It views each
blade from each rotor through a ten degree window and operates on the
principle that a high-flying blade will remain in the field of view longer
than a low flying blade. Installation and operation with Chadwick systems
are straightforward, using aircraft specific brackets and software.
