Q-Alpha Has Been Thoroughly Tested

The Q-Alpha display has been thoroughly tested in Boeing 737-800 and Gulfstream G550 FSI simulators, and in a Cessna182 aircraft.

Test Pilot Testimonials

During the 737 testing, company and NASA test pilots flew more than 200 test conditions that included descents, landing approaches and go-arounds from missed approaches. Pilot comments included:

  • “This device will help guys fly stable approaches”
  • “It kept me ‘on-speed’ without distracting from other tasks”
  • “The display gave me a timely alert when airspeed deviated below Vref”
  • “It made the Go-Around feel safer, especially ones that were initiated late”
  • “This display will reduce FOQA exceedences”
  • “Go-Arounds will be much less likely”
  • “Having the ‘green doughnut’ in my peripheral continued to make me comfortable, especially during Go-Arounds. And I never had to look at it.”

The tests at NASA confirmed that the algorithms in the Q-Alpha display are robust and effective and that the alerting approach was: “Instantly recognizable, clear and unambiguous, especially to distracted pilot”. These are the keys to our competitive position in the market.


Asiana 214 Simulation

During the crash of Asiana 214 on a clear day in San Francisco the on-board air speed alerting systems gave the first warning at 114 knots, an altitude of 100 feet and 11 seconds prior to impact – too late for a recovery. It has been established that recovery was not possible no matter what the pilot did.

The Q-Alpha Display would have provided a warning at 132 knots, an altitude of 480 feet, 31 seconds prior to impact – allowing an easy recovery. In the following video of tests at NASA, the pilot was instructed to ignore the Q-Alpha alerts during a simulated approach at SFO. It shows that the Q-Alpha alerts would be virtually impossible to ignore in real life.
