The Ref. Meteo Time RESET button sets the Reference Meteo Time
back to zero minutes. This is used in conjunction with the interval
settings to control dynamic weather as explained next.
REFERENCE METEO TIME
The Reference Meteo Time is simply an elapsed time counter that
runs as the aircraft is flown. The dynamic weather time intervals dis-
cussed previously use this time to determine when to begin changing
the weather as set up by the “From” and “To” parameters. If for exam-
ple you set the bottom layer winds to increase between 005 and 015
minutes and the ceiling to lower between 010 and 020 minutes, these
changes will not begin to take effect until the Reference Meteo Time
reaches 005 minutes. At 005 minutes the bottom layer winds will
begin increasing (and continue increasing) until 015 minutes where
the “To” parameter values will have been reached. Five minutes after
the bottom layer winds begin to increase (010 minutes) the ceiling
begins to lower and will continue to lower until 020 minutes. Weath-
er parameters that do NOT have a time interval set (static weath-
er) remain con-
stant.
