JPI EDM 900 C or F

[Jim Peace]

My installer is giving me the option of having C or F for temps. 

This is going in a 1964c. My current Garwin system that came with the plane is in F. 

Is there really a choice I have?

Is there a preference of C or F if the data is sent out to a third party for analysis?

thank you in advance

I would think its personal preference but most everyone I've seen has everything set up in degrees F.

Anyone you send it to would be able to convert it at their leisure, but when you are looking at it in the plane, what makes the most sense to you? Are you looking to keep your CHT's under 400F or under 204.4C? Oil temp of 190F or 87.8C?

Pilot's choice.

For the OAT displayed you will be able to flop F/C at your whim. The CHT/EGT/OilT would probably be best as F.

[Jim Peace]

That is what I figured.  F it is.....

Unless your POH limitation are given in both C and F, they shouldn't be giving you a choice. But everyone uses F in the US. (Mooney does provide different markings for export with a different POH)

 

That said, I do work with all units at SavvyAviation because we have clients all over the world. It's a bit of a hassle since all specs originated in the US in F and Gallons (and pounds). But the one exception is OAT where most of us prefer C since it's the temp relative to freezing that we care about. Plus chance of icing is better represented in C. JPI makes it easy to use whatever you want for OAT without effecting EGT/CHT/TIT Etc

For TAS indicators the OAT temp/alt widow is in centigrade. I have a UBG-16 and can switch OAT F to C on the fly for setting the TAS.

For me, I have the Aspens displaying in Celsius and the JPI in Fahrenheit.

Same here.
