Julian,
I can understand your concern, you have just spent £1300+ buying and fitting a PowerFlarm Core to your aircraft which won't be able to see all those who have instead gone down the cheaper PilotAware route. Been there got the tee-shirt and sent it back due to problems I don't want to go into here. That won't however stop me going down the FlarmMouse route if I choose to do so.
Unfortunately, trying to justify your expenditure by making PAW seem much more expensive than it actually is won't help you see PAW equipped aircraft. Your financial argument quickly falls apart because most of us these days already choose to run some form of tablet based navigation system, irrespective of whether or not we choose to install an aircraft avoidance or awareness system, so you really can't justify taking the cost of the navigation system or tablet into account. Many PFC users in fact spend a fair bit more specifically to present data from their systems visually onto SD or their favoured tablet based Nav system.
What Lee is trying to do at the request of PAW and Flarm users is come up with a workable solution without illegally decoding Flarm's Collision Avoidance Protocols, which will allow Flarm users to see us for a minimal cost if they already run a tablet based Nav system and allow us to legally see them at minimum extra cost if we choose to do so.
I don't mean to be offensive or negative in any way, but as Keith says we all have a choice - yours is no more right or wrong than anyone else's - just different.
I for one will continue to await developments
Regards
Peter
