NOTE: The TRK DATA signal from magnetic pickup
channel B is a relative number representing the blade track
pulses coming in from the FasTrak
®
. The magnitude of
these numbers can change based upon the blade height
deviations and rotor speed. It may vary slightly as blade
track height varies. It is presented mainly to insure that
stable track pulses are being received. If this number is
zero, check the FasTrak
®
connections. If it varies widely,
check sun position into the FasTrak
®
lens or the condition
of the paint on the blades.
