ems guy Posted July 11, 2022 Report Share Posted July 11, 2022 how do you find the outside air temperature starting limitation Quote Link to comment Share on other sites More sharing options...
R0T0R Posted July 11, 2022 Report Share Posted July 11, 2022 You’ll have to be a bit more specific. Some aircraft have a “cold weather operations” supplement. Others will have limitations based on the fluids in the aircraft. What aircraft are you operating? Most are -40° though there are some that are only -25°.

DGP Posted July 12, 2022 Report Share Posted July 12, 2022 Thats why everyone preheats the ships. My personal limit is -20...had enough days flying around at -40! Especially while parked in the boonies waiting for hours on the customers... 2 Quote Link to comment Share on other sites More sharing options...
DGP Posted July 13, 2022 Report Share Posted July 13, 2022 If you have ever seen a jetbox running at temps of -40...it looks like a steam locomotive...you would swear that you blew a seal in the turbine!!! 1 Quote Link to comment Share on other sites More sharing options...
R0T0R Posted July 14, 2022 Report Share Posted July 14, 2022 I moved a drill a few years ago and it was -38. Every time I looked outside, I could see white plumes of smoke coming from my exhaust. Even though I know what it’s from and that everything was fine, I couldn’t help but keep an eye on that oil pressure gauge and check the level when I fuelled up.

DGP Posted July 14, 2022 Report Share Posted July 14, 2022 I think I may have told this story before but I was going into a tower site in March in Manitoba and as I was come into a high hover smoke from the engine was so bad that I could hardly see out the windows and then the rear seat passenger on my side open his door and jumped out as he later told me he thought the ship was on fire...I had a seal blow out in the turbine. When I opened the cap on the oil tank...it was almost empty. I also had questions to ask the passenger about where he got the brilliant idea about jumping out of the ship!!!Temps were around -40!!!
