Ultrasonic Altimeter for the Searey Experimental Aircraft
What is FlareAssist, and why should I use this?
Barometric altimeters are very useful in flight, but they are not accurate enough to be helpful when nearing water or terrain. So pilots must learn to use visual clues to judge the aircraft’s altitude, to maintain terrain clearance; and to arrest the rate of descent for flare and landing. Unfortunately, visual clues are not always available or can be dangerously misleading.
FlareAssist uses rapid pulses of ultra-high frequency sound waves, then annunciates the computer-filtered results in the pilot’s headset. This allows the pilot to devote all his attention to flying the aircraft while knowing the actual height of the hull above the surface. Though radar altimeters could in some cases be useful in experimental aviation, their complexity and expense are prohibitive. FlareAssist offers a simple, accurate and economical ultrasonic solution.

FREQUENTLY ASKED QUESTIONS:
1) Can FlareAssist be installed on a certified aircraft?
FlareAssist is not TSO'd and currently available for Ultralight and Experimental Aircraft.
2) How is the FlareAssist installed?
The FlareAssist unit consists of a transducer mounted to the outside of the aircraft which sends a ultrasonic pulse to the surface. The software measures the reflected wave which is then interpreted in the cockpit and annunciated through the headset. FlareAssist becomes 'live' once the airspeed reaches between 45-50 mph, therefore you will need to connect the FlareAssist module into the pitot system.
3) Can the FlareAssist be installed on other aircraft?
4) Is the FlareAssist portable?
Yes, FlareAssist can be removed from the aircraft. Both the Transducer (mounted to the outside of the aircraft) and the FlareAssist cockpit unit have are calibrated after installation on the aircraft. If the FlareAssist is to be moved to a different aircraft type, the unit will be need to be calibrated.
5) Will FlareAssist work on other surfaces, other then water?
Though FlareAssist is intended for use with glassy water operations, it works over smooth water, choppy water, asphalt runways, dirt runways, and grassy areas. Over grassy areas its possible to get a few errouneous results as the ultrasonic waves bounce off of blades of grass at different angles. At this time we do not recommend its use over snow.
