Provides for entry and display of A/C data

What is Multipurose Color Display (MPCD)

Used as a multifunction display; One displays the map video as a background and the other display provides symbology

What is the Digital Map Set (DMS)

A part of the tactical A/C moving map Capability (TAMMAC) system. Provides enhanced navigation/tactical situational awareness to aircrew

Describe the function of Solid State Recorder (SSR)

Recorde cockpit and sensor video, stores offboard images received from the DCS and MIDS communication system

Describe the color and placement of Position lights

Used to determine relative position of A/C at night. Left wing light is Red Right wing light is green Tail light is White

What is the purpose of the strobe light

Anti-collision lights that provide coverage Forward, Aft, Up, Down, and Outboard. Located on the vertical stab and guard against in-flight collisions

What is the purpose of Landing/Taxi lights

Used for landing and Taxi operations at night

What is the purpose of Approach lights

Located on the nose landing gear strut and activated when all landing gear are down, locked, and all weight is off the wheels

What is the purpose of Formation lights

2 Green lights on each wing tip, 1 outside each vetical stab, 1 on each side of the forward fuselage. Used during Join-up after take-off, in-flight refuelling,and routine night formation flights

What is the purpose of the Deployable Flight Incident Recorder Set (DFIRS)

Enables the Storage and retrieving of flight data before A/C crashes. Can transmit for upto 72 hours on Military UHF guard frequency of 243Hz

Explain Pitot Static System

Measures Temp, Pitot, and Static pressures surrounding the A/C
