NOTE 2: Linear PCMCIA cards cannot be formatted/read/written using the embedded laptop reader/writer and are not compatible with Windows OS. Therefore, the use of an Omnidrive device is strongly suggested for the use of these cards.

What tools do I use to program the PCMCIA cards for my EGPWS? Do I need to update the laptop drivers?

Honeywell recommends the following:

1.Standard method - PC Card Manager software 

2.Alternate method - OneNav+ tool software

3.Use of the Omnidrive as the external PCMCIA card reader

A. PC Card Manager software is included with the Omnidrive:

a) The Omnidrive can be purchased from Honeywell: 800-247-0230 or DSA@honeywell.com

b) The Omnidrive is also commercially available on the Synchrotech website.

  • For further information on the Omnidrive, check the manufacturer CSM website. Customer must use the USB2 LF version so that it works with both ATA and linear cards.
  • Customer should always update the driver software after purchasing the device, select the version applicable to the Windows operating system: Downloads

B.  If using the OneNav+ tool:

a)  Download from the Software & Data Services (ASDS)

What Class Type of TAWS Are Honeywell EGPWS MK V/VI/VII/VIII/XXII?

All EGPWS are Class A TAWS except those listed below, which are Class B:

KGP560
KGP860
KMH820
KMH920
MK XXI

Class A TAWS includes all the requirements of Class B TAWS, below, and adds the following additional three alerts and display requirements of:

  • Excessive closure rate to terrain alert
  • Flight into terrain when not in landing configuration alert
  • Excessive downward deviation from an ILS glideslope alert
  • Required: Class A TAWS installations shall provide a terrain awareness display that shows either the surrounding terrain or obstacles relative to the airplane, or both.

Class B TAWS is defined by the U.S. FAA as: A class of equipment that is defined in TSO-C151b and RTCA DO-161A. As a minimum, it will provide alerts for the following circumstances:

  • Reduced required terrain clearance
  • Imminent terrain impact
  • Premature descent
  • Excessive rates of descent
  • Negative climb rate or altitude loss after takeoff
  • Descent of the airplane to 500 feet above the terrain or nearest runway elevation (voice callout "Five Hundred") during a non-precision approach.
  • Optional: Class B TAWS installation may provide a terrain awareness display that shows either the surrounding terrain or obstacles relative to the airplane, or both.
How Can I Perform a Flight History Download From a MK V/VI/VII/VIII/XXII EGPWS?

Pub No. 060-4199-115, which can be downloaded from the EGPWS website, provides the detailed procedures to download the Flight history.


To purchase the PCMCIA Card necessary for this procedure, contact:

Honeywell Complete Customer Care Center

Telephone: (800) 601-3099 (U.S.A.) (602) 365-3099 (International)

E-mail:  orders@Honeywell.com

Alternatively, customer can contact:

Software & Database Services

Telephone: (800) 247-0230

E-mail: DSA@Honeywell.com

For MK V and MK VII EGPWS request Flight History Download Card P/N 718-1592-001. For MK VI and MK VIII and MK XXII EGPWS request Flight History Download Card P/N 718-1593-002.

NOTE: Flight History Download cards have a special Honeywell programmed format that is required to initiate the download sequence and record the data.  The Fight History Download cards (P/N 7181592-001 and 718-1593-002) are not interchangeable. 

What software do I need to communicate with the EGPWS unit?

A.  There are three options of software:

1.  Winviews 64 is available for order through Portal or Orders@Honeywell.com.  PN 69004615-502 Rev A. This version will work with any 64-bit operating system of Win 7 and higher.

2.  The older WinViews V1.0 tool can be downloaded from the Honeywell portal,  requires any 32-bit system, preferably Win XP, but will work with any 32-bit OS of Win 7, Win 8, or Win 10.

•  If 64-bit Windows 7 professional or higher is used, then first option would be to try the compatibility mode: after installing WinViews, right-click on the executable file (not the shortcut but on the .exe file that normally is stored in the WinView folder in the Program Files (x86) folder). Click on the option "Properties" at the bottom of the menu, then on the "Compatibility" tab. Enable the option "Run this program in compatibility mode for" it and select the appropriate option - for instance, Windows XP, or other one that would point to a 32bit system. 

•  Another option is to use a virtual machine (VM). Refer to SIL D201308000012 - available from the myaerospace portal. This SIL  provides guidance on the acquisition and use of this tool.

•  If the above options do not work, there is a terminal emulator freeware called TERA TERM that can be downloaded from a browser. All the commands work the same as WINVIEWS. The freeware is 64-bit compatible.

Customer will have to set up the port in device manager, and serial settings: 19200 baud, no parity, 8 bits, and 1 stop bit.

B.  Required interface cable should connect to the pins shown:

NOTE: As for the USB to Serial Port cable connector adapter, it has to be Windows 10 compatible and they cost a bit more than the regular USB to Serial Port adapter.  Bendix King uses the following for the KGP units: Tripp Lite Keyspan USA-19HS

The light CARD CHNG is on when trying to load the terrain database (TDB).

CARD CHNG LED on typically means that the file is corrupted or not a valid file, or the contents are not recognizable, or the card is suspect. Ensure the downloaded TDB files are unzipped prior to loading or copying into the PCMCIA card.

If the CARD CHNG LED has illuminated, check for the following problems:

1.  Card is blank.

2.  Card has the ZIP file written to it and not the actual BIN file. After downloading from ASDS website make sure to unzip, before programming using the Omni Drive and PCM.

3.  Card is the wrong type (linear vs. ATA). Linear for MK V/VII, and ATA for MK VI/VIII/XXII.

4.  Card is the wrong size, or damaged. PCMCIA cards are fragile and can be damaged if inserted the wrong way. 

5.  Data in the card may be corrupted.


If Honeywell provided the PCMCIA card, please contact ASDS Accounts team for warranty issues at DSA@honeywell.com, or (800) 247-0230.

MKV/VII Red Computer FAIL LED After Loading Terrain Database With FMJ PCMCIA Cards.

Customer should attempt an alternate loading method mentioned in SIL D201712000005 from  Tech Pubs, Paragraph 1.B.2c:

The typical loading method is to insert the PCMCIA card into the EGPWS while the power is turned on. The EGPWS will then read the PCMCIA card and perform the data load. However, testing has shown that even with the write protect switch turned on there is a small chance that the data load will not work correctly. In this case, the PCMCIA card will not be corrupted and a data load may be accomplished as follows:

  • Turn power off the EGPWS.
  • Insert the PCMCIA.
  • Turn power on the EGPWS.
  • While the databases are being installed the IN PROG LED will light and the COMPUTER OK LED will turn off.
  • After the databases are installed, the XFER COMP LED will turn off.
  • Remove the PCMCIA card from the EGPWS.
  • After approximately 15 seconds, the COMPUTER OK LED will turn on.

NOTE: This indicates the database was installed correctly.

How do I deactivate RAAS on my EGPWS?

To remove or deactivate RAAS from a EGPWS unit, customer can load a disable key PCMCIA card PN 718-1597-006 or send the unit to repair shop to reload the EGPWS application software and this will install null RCD which erases all traces of RAAS.

Refer to SB 965-0976/1690-34-90 in Tech Pubs.

Can the MKV-A be used as a drop-in replacement for the MK-V or vice versa?

The MKV-A is designed to be backward compatible with the MK-V EGPWS, but it requires certification before it can be used as a drop-in replacement for the MK V in existing installations. Customer must check with aircraft OEM.

The current MK-V cannot be used as a replacement in new MKV-A installations where configuration files are used to provide aircraft configuration information in place of program pins. This new configuration file approach is being used for Boeing aircraft delivered with the MKV-A. 

The volume for Runway Awareness Advisory System (RAAS) callouts are too loud, how can I adjust them?

RAAS employs three default audio volume levels:

1.  High -The Taxiway Take-Off Advisory is issued at the EGPWS caution and warning alert volume level plus 3 dB.
2.  Medium - Distance Remaining Advisories are issued at the same volume level as EGPWS cautions and warnings.
3.  Low -All other in-air and on-ground advisories are issued at the same volume level as the EGPWS cautions and warnings volume level minus 6 dB.

EGPWS software -222-222 and later support adjusting the volume level of each RAAS advisory via the loadable RAAS Configuration Database (RCD). Changes made to the volume of RAAS using the RCD will have no effect on the EGPWS caution and warning alert volume, which will remain at the level it was originally certified. See service letter EGPWS-MKV-MKVII-57 in Tech Pubs for more details.

In software -220-220 and earlier, to raise or lower RAAS volume requires adjusting the master EGPWS volume and will affect both RAAS advisories and EGPWS cautions and warnings. Volume change is achieved by audio panel/pot adjustment (if installed) or modification of the EGPWS configuration strapping.
