RR 250 starting characteristics
All,
I recently took delivery of a new Enstrom 480B with a RR 250-C20W engine. This engine seems to start differently from the other 480's I have flown. On the first start of the day, the engine accelerates normally until about 40% N1; from 40% to 60% N1, the engine accelerates much more slowly than others I have experience with. On the second and later (warm) starts, the engine accelerates rapidly through the 40% to 60% zone, and stabilizes at about 62% N1. Just wondering if this slow acceleration on the first start is an issue, and if so, is there a fix for the problem? (The engine has 25 hours TTSN.)
