Flight Deck Auxiliary Audio Panel
FDAAP

Palomar Display Products has designed and fielded several variations of this panel for military airborne systems. These audio control panels are used primarily on 737 based aircraft.

The FDAAP (Flight Deck Auxiliary Audio Panel) and RHF (Reduced-Height FDAAP) are mission critical, digital secure voice interface to the aircraft mission intercommunication system, FDR (flight deck recorder), and ACP (audio control panel). The FDAAP is located on the flight deck; pilot, copilot, and navigator actions are routed from the edge-lit font panel through a microprocessor to application specific software with bit (built-in test). The FDAAP meets the black line conducted requirements of NSTISSAM TEMPEST/1-92; the unit provides an isolation of no less than 100 dB between unclassified and classified channels.

This FDAAP can be retrofitted to provide specific control functions; one VME slot accepts customer-specified PWA interface. This unit can be programmed to accept full external I/O control. The RHF unit provides full electronics with half user input capability.
