Precision Approaches average 5 times safer than Non-Precision

If you currently operate using non-precision approaches, the APALS Navigator can   improve your safety by 3 to 8 times (5 times world-wide average)  by providing a precision approach environment for all your destination runways.  It will probably improve your minima as well.   Mounted completely on-board your airplane, the APALS Navigator provides Cat III quality glideslope, localizer, co-located DME, marker beacons, and even the identification morse code -- keeping your operational procedures just like they are!

The APALS Navigator is the tool and Radar Pilotage™ is the method.  Using small, fixed patch antennas and weather radar frequencies, the APALS Navigator makes radar images of the terrain and cultural features alongside the aircraft's flight path.  Just as a pilot uses visual pilotage to determine his position by correlating between the out-the-window view and his maps, Radar Pilotage uses these real time radar images and its internal radar maps to determine the aircraft's position and altitude within 1½ meters.  And even better, this position is relative to the threshold of the runway, is available in any weather you care to fly in, and meets all of the requirements for  Category III ILS ground equipment.

APALS Navigator outputs are designed to drive classic steam gauge avionics, the latest glass cockpits, Head Up Display/Head Up Guidance Systems, and our own Same-As-Visual Equipment.   And if you could also use an integrated inertial reference unit with fully integrated GPS/WAAS/LAAS capability, your in luck since it comes standard in the box.

Operating with your existing avionics, APALS Navigator can provide you with precision approaches to almost all of the world's runways.  When operating in this mode, APALS provides a high quality equivalent of an ILS ground system but the minima is still affected by obstacles, runway and approach lighting, and the airplane's avionics and autopilot certification.

APALS works just fine at runways where a real ILS can't be installed, it doesn't need sterile areas or any other improvements on the ground.  Their is no need for any runway or airport improvements except an instrument paint scheme on the runway. 

APALS is also capable of allowing your classic avionics to fly advanced approaches including complex three-dimensional curved paths as simply as engaging the glideslope and localizer capture modes.
