NOTE:
The following recommendation
is only applicable to aircraft equipped with the Electrical Clock
P/N APE5100-1:
During the entire
month of February, intermittent erroneous indications (wrong, over-range
or missing digits) of the elapsed time and chronometer functions may
occur if the clock is in GPS mode.
In that case, the
flight crew must set the clock selector to internal (INT) mode in order to recover the elapsed time and chronometer functions.
The clock is considered operative.
When the clock is
in INT mode, the flight crew must synchronize the clock
with the GPS at least one time per day to comply with the
time precision required for ATC datalink communication.
Refer to FCOM/DSC-31-55-20 Operation in Internal Mode.
