The subject of whether or not to install a transponder in the aircraft that you are currently building has been hashed over pretty thoroughly recently from many aspects except for this one: 1) Suppose that you are flying around in (relatively remote) airspace that does not require a transponder. Further suppose that you are a very safety conscious individual and that you have you and your aircraft equipped with: a) A GPS capable 406 ELT (http://www.aopa.org/whatsnew/regulatory/elt.html), b) A hand held portable radio, c) A cell phone (both with well charged batteries), d) And maybe even a PLB (http://en.wikipedia.org/wiki/Distress_radiobeacon). 2) You are flying several thousand feet above ground when your engine suffers an unrecoverable failure. As you glide down you take some comfort in having each of the tools listed in 1 above available, but each of those tools (and your ability to operate them) severally have failure modes during and after contact with the earth's surface. 3) But you have one other very powerful tool available to notify ATC (even if you are not in radio or ongoing flight following radar contact with them) that you have both an emergency and your present location IF you have an operable transponder on board and you squawk 7700. 4) Points have been raised about cost, weight, and obsolencence of avionics systems in general. Modern, lightweight, solid state transponders that will remain useable in the ATC system for the foreseeable future are available for less than $2,000. Is that a good investment for you and your aircraft? 5) Please keep 3 and 4 above in mind, as well as the many other points that have been made on this subject, as you consider whether or not to install a transponder when you build your aircraft.

We are only 8 yrs, 2 mos from mandatory ADS-B out for all the same airspace where Mode C is currently required. How long Mode C will remain useful after that date is unknown, as is whether the feds against aviation will extend the ADS-B deadline. Costs have come down on the 1090-ES Mode S transponders, with some in the $2000-2500 range. Since many of us live/base under a Mode C veil now, lack of a transponder is rather confining. Most of us on the other hand won't have a need to reach the flight levels, so UAT may be a better option, but haven't seen many units on the market, so far.

I find that at the altitudes I often fly, loss of radar is common. I still say that it is up to we aviators to decide what we need and how we operate. There is no other entity that will have our best interests covered as well as we will. As Always, It All Depends! Happy Skies, Old Bob In a message dated 10/19/2011 9:33:50 A.M.
