The stopwatch. Use the relevant main menu item to start, stop and reset the stopwatch. The
stopwatch is independent of any flight operation and can be used for various tasks. Often, it
can be a useful aid as leg timer during navigation competitions. The range is to 60 minutes
with a one second resolution and thereafter to 99 hours with a one minute resolution.
The stopwatch can be used in one of the following ways:
Method one
:
Clearing the stopwatch to zero and timing the current leg only.
Activating the stopwatch
Step one: Press Menu, then press Next until cursor is on the Stopwatch menu item.
Step two: Press + to start the stopwatch
Step three: Press - to Zero the stopwatch if required
Step four: Press Menu to exit
Deactivating the stopwatch
Step one: Press Menu and then use Next to select the stopwatch item
Step two: Press + to stop
Step three: Press Menu to exit
Resetting the stopwatch to zero and starting/stopping are two different operations. This
allows you to stop the watch and restart at a later stage without clearing the reading if
required.
HOBBS METER
The hobbs meter shows your engine running time. The hobbs meter is presetable to your
current engine time (User setup menu). Engine running time accumulates when the engine
revs is above the “hobbs revs” as defined in the “Basic setup menu”. This setting allows you
to ignore idle time if you so wish.
MAINTENANCE METER
The maintenance meter is a “hobbs meter in reverse”. You set the meter to your desired
engine maintenance interval (for example 50 hours) in the “user setup menu”. When the
meter has counted down to 0 hours, your maintenance is due.
