I'm currently building a PFA permit aircraft (Pioneer 300) and am contemplating the avionics fit.
The question is, should I fit a transponder, and if so, which
Choices:
i) Dont bother fitting a transponder in the hope they'll never become mandatory (I am aware of the representations against compulsory Mode S)
ii) Fit a mode C at a cost of abt £1000, in the hope that Mode S will not become mandatory
iii) Bite the bullet, fit a mode S at a cost of abt £2000 - £3000 in the hope that mode S wont be superceded by future technology (IDSB?)
I would certainly prefer the safety of a squawk, but dont want to shell out thousands of £s on redundant technology or un-needed sophistication.
Any prooners in the know able to proffer some advice?
