Flight Log - Spektrum AR8020T Guide De L'utilisateur

Flight Log

Flight Log data can help you optimize the control link for your aircraft. Flight
Log data is displayed on telemetry capable Spektrum transmitters.
Using the Flight Log
A - Fades on main receiver.
L - Not available on AR8020T
F - Frame losses
Fades
Represents the loss of one bit of information on one receiver. Fades are
used to evaluate the performance of each individual receiver. If any single
receiver displays higher fade values it should be inspected and the antenna
repositioned to optimize the RF link.
Frame Loss
A frame loss occurs when one complete data packet is missed. A single
frame loss does not represent a loss of control, but frame losses should be
monitored. In the air it's normal to experience as many as 100 frame losses
per minute of flight. On the ground the number of frame losses will be higher
because the signal is hampered by earth and moisture.
Hold
A Hold occurs when 45 consecutive frame losses occur. This takes about one
second, and in this event the receiver moves the channel outputs to the failsafe
settings. If a hold ever occurs, it's important to re-evaluate the system and
check every component. If your system displays a hold taking place, diagnose
the cause and resolve the issue before flying again.
It is normal to see a hold logged if you power OFF your transmitter and back ON.
IMPORTANT: The Spektrum Flight Log (SPM9540) is not compatible with
the AR8020T receiver.
