Mike as you say the audible stall say on a C 150 was as a good indication and not a distraction.The “inevitable” “behind the curve” warning as you flare is no different to the stall warning on most aircraft. In fact I’ve found it a good indicator that I’m not landing too fast. If I start to flare and don’t get that message I know something’s wrong. Also the GWS includes a volume controller (you can’t turn it down below a certain level) and a push button to stop the message for a set time period (actually at 20 seconds but adjustable).
Thanks for your interest. When I've managed to get a vaccination and can travel to the USA, I'll plan a visit to Florida, I probably need to update you on the latest PB4 features and will bring a prototype GWS for testing.
At the moment the GWS does all you ask up to number 6. You can see from the graph the different outputs, the height is barely visible because in that particular test I never took off.
We are looking at adding engine rpm and it doesn't seem to be a problem.
Fireproofing is something that we're looking at but needs to be discussed with those manufacturers who we will be working with to see how much they want to do. Since they have to find somewhere to fit this black box they may have better solutions than us.
As a point of interest does anybody have an idea of which zone of a gyro is the least likely to be affected by a crash and fire?
The GWS also has a set of contacts for a door/canopy lock alarm.
We hope to work with interested manufacturers and this may produce other requirements.
