I have the latest versions of the B377 (v2) and Cots (1.1) installed. The problem I am having is that sometimes I can start the engines and sometimes I can't. The temperature has been in the -5 to 5 degree C range most of the time when I'm trying to start a flight. I've read other posts about cold weather ops, but I wouldn't think that these temps are low enough to fall in that category.
I follow the checklist/procedures from the manual as close to the letter as I can. I've also tried variations (e.g., various cowl flap settings, mixture full rich, throttles more than an inch, etc), but I don't see any difference. When an engine fails to start, I've never been able to get them started regardless of what I try. When I check the maintenance report, the engine condition is reported as excellent. After attempting to start them for awhile the condition will drop to Good. I also will delete the files in My Documents\A2A and service the engines on almost every flight attempt, but the results are the same. Sometimes they start and sometimes they don't. Sometimes I'll get 1 or 2 engines started but the others won't.
I really like this aircraft sim and have had a couple of successful flights. However, most of the time I end up shutting FSX down feeling discouraged because I had my flight planning done, pre-start checklists done, passengers loaded, fuel loaded, clearances, push-back .. only to spend a long time trying unsuccessfully to fire up the engines. It's very frustrating when you spend over half an hour preparing for a flight only to have it end this way over and over.
Anyway, I sure hope there's just something I'm overlooking here. I've tried all I can think of based on the manual and on reading other posts. As much as I dislike having to do so, I must ask for help.
Thanks in advance!
