below the antenna beam scan resulting in a blank display. Alternately, under-scan, where the antennas scan is
hitting the ground below the weather cells, results in ground clutter display. The calculated tilt angle is transmitted
on the ARINC 429-output bus (labels 061, 062, 063, 064, and 065) for any compatible Weather Radar system. See
the appropriate Part Number ICD for complete Label definitions.

2.2.14 SYSTEM DISPLAY AND ANNUNCIATION
In addition to the aural (voice) alerts provided over the cockpit speaker and interphone system, the EGPWS drives
cockpit annunciators and/or Electronic Flight Instrument Systems (EFIS) with system status and alert annunciations.
For some EFIS displays, the EGPWS is designed to interface and display the EGPWS terrain video as well as alert
annunciations directly onto the EFIS without the use of external relays or annunciators. This is referred to as an
“integrated” EFIS display. For other displays (some EFIS and all Radar Indicators), the terrain video is relay
switched into the display system externally taking the place of weather radar video. In this case, external switching
and annunciation is required. This is referred to as a “Bolt-On” display. The interface and display characteristics
are defined for each display system and programmed into the EGPWC as part of the configuration software.

Cockpit annunciations can vary somewhat aircraft to aircraft or operator to operator. In addition, several system
options are defined by the installation configuration. One of these is EGPWS lamp format. Two formats are
provided; Lamp Format 1 and Lamp Format 2. They are described and illustrated in the next page.

2.2.15 RUNWAY AWARENESS AND ADVISORY SYSTEM (OPTION FOR MK V AND MK VII
ONLY)
The Honeywell Runway Awareness and Advisory System (RAAS) offers significant safety enhancements for aircraft
equipped with Honeywell’s MK V or MK VII Enhanced Ground Proximity Warning Systems (EGPWS). Honeywell’s
Runway Awareness and Advisory System is a software enhancement hosted in the EGPWS Unit. RAAS uses GPS
position data and the Honeywell EGPWS Database to provide aural advisories and alerts that supplement flight
crew awareness of position during ground operations and on approach to landing. EGPWS protection and operation
is unaltered by the addition of RAAS. RAAS installation is accomplished via a configuration database upload. The
installation does require that the EGPWS has a source of GPS data, software -218-218 (or -002 or -051) or later,
Terrain Database version 435 or later (454 or later if using software -230-230 or later), and the RAAS Configuration
Database (RCD) or Reloadable Customer Definitions (RCD) is loaded. When enabled, RAAS operates
automatically, without any action required from the flight crew. RAAS availability can be verified by performing an
EGPWS self test. See Appendix C for RAAS Maintenance Messages.

2.2.16 STABILIZED APPROACH MONITOR (OPTION FOR MK V AND MK VII ONLY)
The Stabilized Approach Monitor function offers significant safety enhancements for aircraft equipped with
Honeywell’s MK V or MK VII Enhanced Ground Proximity Warning Systems (EGPWS). Honeywell’s Stabilized
Approach Monitor is a software enhancement hosted in the EGPWS Unit. Stabilized Approach Monitor uses GPS
position data and the Honeywell EGPWS Database to provide aural advisories and alerts that supplement flight
crew awareness of unstabilized approach to landing. EGPWS protection and operation is unaltered by the addition
of Stabilized Approach Monitor. Stabilized Approach Monitor installation is accomplished via a configuration
database upload. The installation does require that the EGPWS has a source of GPS data, software -230-230 or
later, Terrain Database version 454 or later, and the Reloadable Customer Definitions (RCD) is loaded. When
enabled, Stabilized Approach Monitor operates automatically, without any action required from the flight crew.

2.2.17 ALTIMETER MONITOR (OPTION FOR MK V AND MK VII ONLY)
The Altimeter Monitor function offers significant safety enhancements for aircraft equipped with Honeywell’s MK V or
MK VII Enhanced Ground Proximity Warning Systems (EGPWS). Honeywell’s Altimeter Monitor is a software
enhancement hosted in the EGPWS Unit. Altimeter Monitor compares Corrected Altitude to the EGPWS blended
Geometric Altitude solution to provide aural advisories that supplement flight crew awareness of incorrect altimeter
setting or problems with the pressure altitude system. EGPWS protection and operation is unaltered by the addition
of Altimeter Monitor. Altimeter Monitor installation is accomplished via a configuration database upload. The
