As the Tyne is a twin spool engine, ie, the starter motor is driving the HP section and not even connected to the prop, LP section,it would need about 50 miles of rope hooked to a high speed train to spin it up fast enough for a start.
That 10 second rule on the starter, only applies if your GPU is top line, the Tyne needs 2,000 amps continious to achieve 2500 hp rpm for a succesful COOL start, any thing less is courting disaster, at least for the turbines anyway.
I'd love to be there to watch EP's engine run,...from a safe distance...about half a mile would be good, I've had one fire during an engine run on a Vanguard and the company refused to pay the dry cleaning bills for four pairs of trousers,

rather than down
We have some steps to move, the engines need to be bled and topped up with oil then the prayer mats positioned to face Mecca so I'll be in early to participate in most of these evolutions and any additional ones that will undoubtedly crop up so let's hope for some half decent weather. There is no opportunity for an early run so as soon as you see the props start to turn (3 and 4).. cross your fingers, legs arms and anything else that comes to hand
