Runway length help.

I'm pretty sure that full power would be set on the brakes and left there for a while until all were happy!

Is this because engine failures are more likely while they're running up to full power and just after they get there? Sitting in a Saab doing the on-the-spot disco dance at the end of 27 at Kirkwall, watching the windsock on Viagra pointing directly across the runway, I've often wondered why there was such a wait between hitting full oomph and actually getting going.

This has been discussed elsewhere. The usual reason is that engines don't all take the same time to run up to full power. So you wait for them to stabilize to the same power, rpm, etc. before releasing the brakes.

The Mini Busses use optimized performance to increase energy in the event of an EFATO, so they try to use increased V2 which sometimes gives some very high speeds on a long runway.

Not always good when the tyre shreds around V1 and you end up with a hyd leak and massive vibration as happened to one of our chaps years ago

Anyone mentioned declared clearway yet?

Can't be bothered to read all the thread, sorry.
