Mark XXI EGPWS

Overview
The highly affordable Mark XXI enhanced ground proximity warning system (EGPWS) adds the powerful safety benefits of EGPWS to visual flight rules (VFR) equipped helicopters without radio altimeters and exceeds helicopter terrain awareness and warning system (HTAWS) requirements. It includes an internal global positioning system (GPS) card and interfaces to weather radar indicators, multi-function displays and stand-alone displays. In addition, we made the installation process simple, so your helicopter can quickly return to flight.

The Mark XXI comes standard with an internal 8-channel GPS card for installations where an external GPS is not available for position input.

Using our proprietary worldwide database (11 regions), including high resolution terrain, airports, heliports, obstacles and oil rigs, our Mark XXI EGPWS incorporates many features not found in competing systems.
Specifications
Key Differentiators
  • Features & Benefits
    • Auto pop-up change from radar to terrain display in the event of a terrain alert, reducing pilot workload during this critical time
    • Geometric altitude algorithm overcomes barometric altimetry limitations, like cold weather operations
    • Instrument flight rules (IFR) operators should consider a Mark XXII EGPWS
    • Option to suppress low altitude mode, audio or terrain according to pilot preferences
