The Gear Handle controls the landing gear and indicates its current status. Indication of the current landing gear position is carried out through three green, three red 'UNLK' indicators and one
additional red 'Gear Warning' (GND = Active) indicator.
The landing gear lever has to be pulled out, before it can be moved to either up or down position. While the aircraft is on ground, the Gear Handle lever is locked in its down position to prevent
movement of lever to the upper position, so that retraction of landing gear is not possible.
An additional 'MUTE' push-button on front panel is available, which activates a GND Signal output on corresponding pin of connector J1.
