I've just started flying a turbine so still crapping myself on each start!
A good battery is certainly your best friend as a turbine newbie. Looking at the various turbine starts on youtube, there seem to be some variances in the rate at which N1 increases from the second the start button is pressed on different helicopters. The N1 on the turbine I am fortunate to be flying seems to accelerate fairly quickly compared to some on youtube. That has me thinking: What if you pass 15% and you haven't introduced fuel? Is there any damage done to the engine if fuel is introduced at 17, 18 or 19% N1? I lit off one start at 15% and the TOT stayed well within limits but the manual recommends various starts at 13%, 14% or 15% depending on the outside temperature. Thanks.
