Jim Phelps 2749H > ----------------------------------------------- Yo, Jim I'll have to admit that something caused me to post my "William R. Bayne Re: 0200 Conversion 1/31/03 2:03pm" comments with inadequate reference for you to tell it was a response. Lack of oxygen seems a good excuse! Sorry. To see the subject thread where I tried to pick it up, see MAGIC VAC's post of 1/30/03, 9:36am Re: O200 Conversion (TECH Archive). On longer cross-country flights I usually pick between five and eight thousand feet MSL (depending on how high the rocks are, where the winds are most favorable, and the odd/even altitude choices of my course heading. If something unexpected happens at such altitudes in unfamiliar territory, the selection of emergency landing sites is greater than at "pattern altitude". It is common in summer around Albuquerque, NM (and the continental divide) for the density altitude to be as much as four thousand feet higher than the MSL elevation. At 1400 lb. gross weight in a "D" Model (with an advertised ceiling of 12,000'), heading over seven thousand foot high terrain with one thousand foot clearance and such four thousand foot increase in density altitude, you can't climb higher than your 8,000' MSL! If my recollection is not still affected by insufficient oxygen, the aircraft ceiling is a figure taken from observed conditions as corrected to a "standard day". These corrections remove the usual variation between density altitude and actual altitude. Think of this as a perfect "virtual sky" representing conditions seldom actually outside when and where we fly. Your coupe and your brain travel in a sky where density altitude is the only reality. The coupe will do more than most think, but there are limits no one can exceed. The challenge is always to find them before they find you. Regards, William R.
