The compass correction card, sitting above the compass rose, shows the correction values to subtract or add to
the indicated heading for compensation of metallic or magnetic materials in the aircraft, influencing the
compass rose.
CLOCKS
A digital clock is installed on either pilots’ side panel. The clock is normally synchronized with a time signal from
the GPS, which happens automatically during aircraft start-up. In case the GPS sync is interrupted, the clock
switches to internal (INT) mode.
The clock features the following modes
• Display date (GPS or UTC)
• Display current time (GPS, internal UTC or local)
• Chronometer (CHR) function
• Elapsed Timer (ET)
