Flight Deck Audio Panel
FDAP

The FDAP (Flight Deck Audio Panel) is mission critical, digital secure voice interface to the aircraft mission intercom, FDR (flight deck recorder), ACP (audio control panel), and sonabuoy. The FDAP is a split-unit (units share RS-485 serial link). The FDMEU is located in a flight deck rack; the pilot, copilot, and navigator actions are routed from the edge-lit FDMCP to the FDMEU embedded microprocessor. Software is application specific with bit (built-in test). The FDAP 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 audio channels.

This FDAP (FDMEU & FDMCP) can be retrofitted to provide specific control functions. One FDMEU VME slot accepts customer-specified PWA interface. The FDMCP can be adapted for specific user interface and NVIS.
