Midair Collision Avoidance System (MCAS)

The midair collision avoidance system (MCAS) is an inexpensive warning system that prevents midair collisions, which are the major cause of tactical aircraft loss.

Traditional collision avoidance systems are not appropriate for tactical fixed- and rotary-wing aircraft because of space and weight limitations.

MCAS USER BENEFITS

• Minimal probability of detection provided by low-wattage beam, increasing mission success
• High jam resistance
• Low life-cycle cost and high dependability
• Reduced logistics burden through enhanced testability features
• High accuracy at all altitudes and attitudes
• Software-based processing allows for easy modification to meet new requirements
• High commonality across system variants

MCAS FEATURES

• Integrates collision avoidance into existing flight-critical aircraft transponder (AN/APX-117 or AN/APX-118)
• Fits within existing form factor
• Uses existing antennas and wiring
• Makes innovative use of existing Mode S signals (ADS-B)
• Is interoperable with civilian aircraft
• Is under contract for proof of concept
