Today was the first time I flew the RV-12 in COLD weather. Well, 42F here in South Carolina is cold!
A few observations…longer of course to warm up the oil to the 120F mark.
Cylinder heads were top of caution range throughout except during take-off, is this common?
Oil temp lower than I've seen in the hot weather, naturally, but it was about half-way in the green.
Today…fuel pump working fine (and loud) but fuel pressure hovering at the upper caution point…about 2.8psi at 5100rpm and when throttled back it increased to 3.5-4.0 range. I've read here that the higher the fuel flow the lower the pressure…haven't seen this before until recently though. Does the colder weather have any impact?
Engine ran well and started first time on choke.
One other thing..I just loaded the 12SV11.1-Pre-SETS etc upload from the Vans site…looks like they've made settings that came from Dynon on the 11.0 upgrade…like nearest airports color coded for weather conditions…I'll look for other settings. Point I'm making is that some posters said their software settings changed after they uploaded directly from Dynon and Vans had told me that I should wait to upload from their site as they look at the software from the RV-12 aspect. Am I correct here as to how Vans configure the software if you upload it from them?
As always, apologize for newbie questions but trying to learn!! Thanks!
