CLOCK
The clock provides time related information
• CHR: chronometer, start and stop with the CHR button, reset with the RST button
• UTC: shows UTC time
• ET: shows flight time (triggered by flight mode START)
VOR/DME RECEIVERS
There are two VOR/DME receivers and
the information is supplied on the
Navigation Display (ND).
FLIGHT MODE ANNUNCIATOR
The Flight Mode Annunciator is shown at the top of the Pilot Flight Display and is perhaps the most
important display of the whole cockpit. It shows in detail in what mode the systems are operating in and
what the pilot can expect to happen. Understanding what is shown here means understanding what the
aircraft is doing. If a pilot enters the cockpit after a sanitary break it is the first thing he will check. There
are five columns with 3 lines each.
