Mark V-A EGPWS

The Mark V-A enhanced ground proximity warning system (EGPWS) is a replacement for the popular Mark V EGPWS. The Mark V-A is certified to the new terrain awareness and warning system (TAWS) technical standard order (TSO) C151c. The Mark V-A was designed to use the same rack and connector as the Mark V, minimizing installation design considerations. The Mark V-A comes in three versions, 115Vac, 28Vdc, and 115Vac, depending on your aircraft requirements.

Positioned for growth, the Mark V-A incorporates a faster processor and increased memory, with Ethernet outputs available to support advance displays. Installers can use the existing Mark V program pins or select configuration options via a loadable database. Using configuration options like the aircraft personality module (APD) or option selection software (OSS), the pins previously used by the Mark V become available for use as additional input or output channels, further supporting future growth.

Improving on the Mark V, the Mark V-A utilizes a higher resolution terrain database, allows terrain database and software updates via either USB or Ethernet and benefits from a 15 percent weight reduction and 25 percent increase in reliability, or mean time between failures (MTBF).

Frequently Asked Questions

What is the typical lead time for gas turbine overhaul services?

The lead time for gas turbine overhaul services ranges from 6 to 14 weeks, depending on the damage assessment, parts availability, and whether hot-section repairs are required. Expedited options may reduce this by 30%.
Do you provide customizations for legacy turbine control systems?

Yes, we retrofit legacy systems (e.g., GE Frame 5, Siemens V94.2) with modern digital controllers, typically completing hardware integration within 4-8 weeks. Software migration requires additional validation time.
How often should industrial gas turbines undergo performance testing?

We recommend annual performance testing under ISO 3977-2 standards. Critical applications (e.g., offshore platforms) may require semi-annual tests with emissions compliance checks.
Are your radiation-hardened (rad-hard) semiconductors compliant with MIL-PRF-38535?

All rad-hard devices (e.g., FPGA, ADC) are QML Class V certified under MIL-PRF-38535 and tested to MIL-STD-883 Method 1019 for SEU tolerance. Full qualification reports are available upon request.
What temperature ranges do your military-grade ICs support?

Our ASICs and power management ICs operate across -55°C to +175°C ambient temperatures, with derating curves provided in military temperature range (MTR) datasheets.
Are PMA parts interchangeable with OEM components?

Our PMA parts (e.g., actuators, sensors) hold FAA/EASA Form 1 certification and match OEM form/fit/function. Installation requires SB/MB documentation per FAA AC 23.1529.
What traceability standards do you follow for aircraft fasteners?

All NAS/MS fasteners include full DNA traceability: melt source (AMS 2301), heat/lot numbers, and AS9100-compliant MTRs with ultrasonic test reports.
How do you handle urgent AOG (Aircraft on Ground) requests?

AOG orders ship within 4 hours for stocked items (FAA-PMA, EASA Part 21G). Non-stock critical parts trigger priority manufacturing with 72-hour max turnaround.
