Opinions/Experience with PC Flight System's eGyro-3, anyone?
I'm considering trying to convince my club to switch to the eGryo-3 instead
of a differential pressure vacuum backup. However, I'm curious about a couple of things. The differential pressure mechanism is - I believe - STCed. What would we need to go through for a panel mounted eGyro-3 (assuming it isn't STCed)? A field approval, requiring an inspection? Complex? Expensive? We're in the area of the Teterboro FSDO, if that makes a difference. Also, the differential pressure mechanism powers the DG. I see that the eGyro-3 provides AI and TC backup. Does it also provide heading information? Finally, what about electrical problems? The differential pressure mechanism is immune to this, but the eGyro-3 is electrically powered. Of course, PC Flight System has a portable solution, but I'm really looking (at the moment; check again with me in a little while {8^) for a panel-mounted solution. Any insights would be appreciated. Thanks... Andrew |

The differential pressure mechanism is - I believe - STCed. What would we need to go through for a panel mounted eGyro-3 (assuming it isn't STCed)? A field approval, requiring an inspection? Complex? Expensive? Unlikely to be approved for installation if you asked any FAA type. These things do not meet the requirements for aircraft parts. The STC would be the least of your worries. The big question would be if such a system would even require you to mention it to the FAA. I'm not going there, you will get differing opinions from different people. Also, the differential pressure mechanism powers the DG. I see that the eGyro-3 provides AI and TC backup. Does it also provide heading information? Presumably the differential pressure system feeds ALL the vacuum instruments which is typically the DG and the AI. The TC is usually already electric. The eGyro-3 provides only the AI and TC functions (why no heading info I do not know) |
