The candidates are an AeroMech 8141B, an ARC EA-801, and an ARC EA-401. Does anybody know these altimeters and/or have any advice on making this change? Since all three counter-pointer altimeters are the encoding type, I would have to remove my Transcal SSD-120-30K encoder. Is that a wise move? Does anybody have the pin-outs for the cannon-plug on the backs of these altimeters? Thanks in advance, Don ________________________________ Message 2 _____________________________________ Time: 04:41:40 PM PST US From: "Charles Reiche" Subject: Re: Avionics-List: Altimeter Question Encoding altimeters are VERY EXPENSIVE to maintain as a altimeter/encoder system. It is much cheaper in the long run to keep these separate. Call up Kelley Instruments and ask how much an overhual is on one of those units... you can buy alot of regular altimeters and encoders for the price of 1 encoding altimeter overhaul. That Trans cal ssd-120 should last a long life for you. As an avionics tech and installer, I emplore you to keep your 3 pointer system with separate encoder. Save yourself the heartache of failed pitot static inspections and costly overhaul bills down the road.
