Police helicopter crashes onto Glasgow pub

[yellowbird135]

Sid, with regard to your last post....I fully agree..

Here's a 135 question, how many engines are running when you do the Hyd checks?

One, with N2 appr 73-74%, don't do it in the powertrain accelleration phase.....so here"s a follow up question: Is it allowed to do it with both engines idle?
