The system tells people in the flight compartment or outside of the airplane to use the flight interphone system. Between Flight Compartment and Ground Crew A crew member pushes the GRD CALL switch in the flight compartment to call the ground crew. The switch is on the passenger signs panel on the P5 forward overhead panel. A horn (сирена) in the nose wheel well makes a sound when the crew member pushes the switch.     The ground crew pushes the PILOT CALL switch on the external power panel to call the flight crew. The CALL light on the passenger signs panel comes on and there is a high chime from the aural warning module. When the ground crew releases the PILOT CALL switch, the CALL light on the passenger signs panel goes off.
