Sounds very interesting! May I ask a couple of non-forbidden questions please if you can answer without giving away the family jewels!
1) A kind of PAPI/VASI using fixed markers not lights sounds straightforward, but how do you arrange a ‘go-around indicator’?
2) Will it be legal to use such a device or will it need some sort of (CAA) certification?
Best of luck with your innovation!!
Thank you for your well-intended questions. I do always enjoy a little humour, I must say
Although not having given away the family jewels, Piet Meyer did let a fairly large cat out of a fairly small bag!
Let me try my best to answer you . . .
To your first question, from 200 - 300m out from the designated point of touchdown a pilot will easily be able to determine an 'off-glideslope' condition, and the extent of that, which will indicate a 'go-around' decision to any pilot wanting to preserve the wellbeing of self and/or passengers and aircraft. In fact, even before this, if there are obstacles to clear on the approach, the device will indicate the need for a go-around.
The runway-side device is incredibly simple and really intuitive to use. Even non-pilots 'get it', without understanding the complexities that come with having to clear obstacles on approach, or maintain a glideslope in windy or turbulent conditions, or trying to gauge the effect of a sloping up or down runway on the 'runway geometry' we have imprinted /_\, or trying to calculate 5 x groundspeed in knots to determine rate of descent in feet per minute, all whilst trying to focus on everything else that is happening in the landing phase.
I have had a fairly broad circle of trusted, experienced and 'safe' pilot friends (some well-known, like Piet Meyer) review the device throughout the development phase and who have very kindly given their much-valued opinions. At this point, I can gladly report that there has been a 100% 'thumbs up', subject to testing and the necessary approvals, of course, which brings me to your second question.
We are currently engaged with CAA. The testing phase currently underway is intended to test the install/assembly and setting-of-glideslope processes and to derive some statistics on landing accuracy. I'll post pictures of the testing, along with the results, at a later stage.
Hopefully, that provides a little more information, whilst still preserving my crown jewels!
Today is a big day for us. Thank you to all those that have helped us get this far.
