Today's stupid questions (0256 JST
). Is it going to be possible to somehow pimp the GPS output to a Mode S extended squitter to enable SIL 1?
At the moment my plan is to use the GPS output from my MGL EFIS as the position source for a Trig TT21 transponder to enable ADSB Out. As we ALL know (
) this would presently give me SIL 0 and, therefore, cloaking device to certified receivers. Having spoke to the MGL Guru, I am assured their GPS does actually conform to SIL 1 but it would need the paperwork doing before he can turn on the 0s and 1s that would enable the transponder to sense the presence of a pimped GPS signal and switch itself to SIL 1.
According to Trig, the transponder will automatically configure itself to SIL 0 or SIL 1 depending on the GPS 'code' it receives, telling it how good or gooder it is.
I was wondering if there is a relatively easy way for PAW to change the GPS dongle, or whatever else needs to be done, in order to get the proper GPS output signal to an extended squitter to enable SIL 1.
Some might argue this would also slightly mitigate the Sky Echo 2 'threat', as their unit has SIL 1. Of course, it would only affect those using the GPS to a Mode S for ADSB Out but every little helps.....possibly
