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 Digital Distance Radio Magnetic
Indicator (DDRMI) and the Navigation Display (ND).
FLIGHT MODE ANNUNCIATOR
The Flight Mode Annunciator is shown at the top of the Pilot Flight Display and it perhaps the most important
display of the whole cockpit. It shows in detail in what mode the systems are operation 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.
