Flight Log - Spektrum AR9110 PowerSafe Bedienungsanleitung

6. After one minute, a successful range check will have less than ten recorded
frame losses. Scrolling the Flight Log through the antenna fades (A, B, L,
R) allows you to evaluate the performance of each receiver. Antenna fades
should be relatively uniform. If a specific antenna is experiencing a high
degree of fades then that antenna should be moved to a different location.
7. A successful advanced test will yield the following:
H
0 holds
F
less than 10 frame losses
A, B, R, L
Frame losses will typically be less than 100. It's important to
compare the relative frame losses. If a particular receiver has
a significantly higher frame loss value (2 to 3X) then the test
should be redone and if the same results occur, move the
offending receiver to a different location.

Flight Log

The Spektrum Flight Log (SPM9540) is compatible with the AR9110
PowerSafe. The Flight Log displays overall RF link performance as well
as the individual internal and external receiver link data. Additionally it
displays receiver voltage.
Using the Flight Log
After a flight and before turning
off the receiver or transmitter, plug
the Flight Log into the Data port
on the PowerSafe. The screen will
automatically display voltage e.g.
Note: When the voltage reaches
4.8 volts or less, the screen will
flash indicating low voltage.
Press the button to display the following information:

antenna. Typically it's normal to have as many as 50 to 100 antenna fades
during a flight. If any single antenna experiences over 500 fades in a single
flight, the antenna should be repositioned in the aircraft to optimize the RF link.
If the RF link is performing optimally, frame losses per flight should be less than
20. The antenna fades that caused the frame loss are recorded and will be
added to the total antenna fades.
A Hold occurs when 45 consecutive frame losses occur. This takes about one
second. If a hold occurs during a flight, it's important to reevaluate the system,
moving the antennas to different locations and/or checking to be sure the
