Must be a very different wiring situation than most of us have. In most planes, either pressure switch can be fused closed, fused open, leak, fall out, short circuit or undergo any other type of failure and it won't "cause" a gear up landing. Did the fused pressure switch somehow keep you from using the emergency gear extension procedure? Bill, Nice critical analysis - looking for 3 green lights is as important as keeping the runway numbers in the lower third of the windshield. Oh well, being in a state of D'Nile (oops, denial) and blaming hardware, software, O2 or gremlins is always easier. BTW, my hypoxic induced gear-up did provide useful information - a wheel-less Lancair slides to a stop rather quickly and the distance/direction is not affected by applying brakes or rudder and I know because I engaged both. However, one is still required to make a "good" landing. Grayhawk -------------------------------1130774549 Content-Type: text/html; charset="US-ASCII" Content-Transfer-Encoding: quoted-printable
