Various products available for other aircraft are not currently so for Diamonds, such as Dynon. So it's far from "anything you want".pietromarx wrote: ↑Mon Nov 01, 2021 5:00 am In thinking on this for the last few days, I cannot see why you can't put in any instrumentation you want. The engine is a nice 1941 Lycoming that can be monitored by any monitoring system. The flight instruments are generic. There are no airframe-specific sensors or systems other than the autopilot.
As noted, this situation only applies to the DA-40-180. It means that we can have your setup. There is a small, but non-zero, chance that someone might take the lightest weight, too. Woot!
While sensors are not airframe-specific, the sensors are often display-specific/proprietary. A solvable issue, I presume, but it is an additional thing to deal with. If nothing else they need to be rewired. A quick list:
2 (or 4) fuel level sensors (note the challenge of the 50-gallon birds)
2 low fuel level switches
1 fuel pressure sensor
1 low fuel pressure switch
1 fuel flow sensor
1 oil pressure sensor
1 low oil pressure switch
1 pitot current sensor
1 alternator current sensor
1 alternator low voltage sensor
It's likely that the existing EGT and CHT thermocouples will work with any system, as well as the RPM pickup on the mag.
The moral is to do all your research so you know how to address all the facets of replacement.
