Design Engineering Requirements

The following items are required for engineering design. Please advise if these items are available:

  • Digital photos, pictorial or descriptive layout of the current GPWS installation in the E/E bay Yes No
  • Digital photos, pictorial or descriptive layout of the current cockpit configuration including the Capt & F/O Instrument Panels, Circuit Breaker Panels, GPWS related annunciator locations and legends. Either freestanding annunciators or annunciator modules are available for the EGPWS retrofit. Annunciator modules take up more space but are DZUS mounted for ease of installation/maintenance. Yes No
  • Chapter 24-58-11/21, Chapter 33 and Chapter 34 Aircraft Wiring Diagrams Yes No

Equipment Part Numbers and Configuration Issues

The purpose of this work sheet is to obtain the necessary aircraft data to develop aircraft specific interface configurations to support the installation of the Enhanced Ground Proximity Warning Computer (EGPWC).

Listed below are typical parameters from each system which are required to implement the EGPWS functions. Note that this list is a typical example. Actual source systems may vary depending on aircraft configuration and selected options.

System
Parameters
Radio Altimeter radio altitude
ADC barometric altitude, corrected baro altitude, baro rate, computed airspeed, true airspeed, static air temperature or total air temperature
IRS / AHRS magnetic heading, vertical velocity, pitch, roll, normal and longitudinal acceleration
ILS / NAV receiver glideslope deviation / flag , localizer deviation / flag
SWC angle of attack
FMS / GPS latitude, longitude, ground speed, true track, true heading, mag variation, nav mode, horizontal figure of merit, horizontal integrity limit

Additional Data

Does the aircraft have provisions for a GPS Antenna(s)? If so, is either antenna location currently being used? Is the antenna coax installed? If so does it terminate at the E/E bay or in the sidewall? GPS Antenna part number? Station location?

On which shelf is the GPWC currently mounted in the E/E Bay? Length of the GPWC mounting tray (tray size). Does the GPWC mounting tray have a plenum or plenum seal?

Approximately 6" x 6" area is needed on the stanchion disconnect structure near where the GPWC is installed to mount the Terrain Display Relay Module. Is there room to mount the relay module bracket at GPWC shelf disconnect stanchion? (Provide pictures and/or drawings)
