The addition of the HT-295 to Aspen Avionics approved STC list for their insta-pfd makes this odd looking bird that much more attractive. OK, sure that isn't what they call it but I like the name. Perhaps I should trademark it.
Unfortunately, the STC only lists the HT-295 and not the H295 which is a conventional-geared model as opposed to the tricycle gear on the HT version. I was similarly surprised to see that the Cessna 182 (all models it appears) is on the list but neither the 180 or the 185 are.
