Errrr, not always ;)

There was a engine fire on an aircraft at EGCC and the pilot goes V1... ABORT!

But yeahhhhh, nobody knows what where talking about so lets shut up lmao!

Boeing 747 has quite a quick take off speed for its size I would say. Its around 180 mph but it depends on tailwinds, weight, the pilot, run way size and many other factors.

How is it depending on the pilot?

You takeoff into headwind, not with tailwind.. The runway size will be big enough to support a 747 with maximum weight..

Well, the pilot chooses how far he/she taxis onto the runway. The smaller the run way the more throttle you will need. Not a huge factor of course but it would change the speed while on the run way. Some airports have small run ways so they have to really get all the engines going and put it straight onto full throttle. While larger run ways they may choose to build up speed bit by bit until they get up to the take off speed. This wont change the take off speed as such put it will change the speeds while on the run way.

Scrub pilot from my last post tbh :p

im afraid of flying full stop.

Ummm, your just gonna have to trust me on this one.

A pilot NEVER uses full throttle on takeoff, NEVER! - 3/4 throttle.. Aircraft don't usually go full thottle unless there is an emergency, even then it can only be for about 10 minutes.

No matter how big the runway is, the pilot wants to use the minimum possible!

Also, 80% of the time they are cleared for takeoff at the hold - In which case you taxi onto the runway, line up and depart within 15 seconds of recieving the clearance.

The way I've been personally taught is when cleared for take off at the gate, taxi into the centre and roll without stopping at all. If you don't ATC will start shouting "BLEH BLEH ROLL NOW!!"

On landing, the pilot may lay off the brakes for a little while so they can vacate at a later taxiway rather than having to taxi at about 40 knots, however proberbly only when the pilot is familiar with the airport! :)

Anyway, I sound like a complete geek and I'm going to shut up now.

I am sorry to inform that that is wrong.
To/ga handles that and takeoffs are usally no more than 95 n1. you would almost always takeoff in a 747 with to/ga ( take off/ go around) mode which controlls the speeds programed into the fmc. and you would usally taxi from the end of the runway giving you lots of space and most runways are about atleast 6500 ft where a 747 flies.
Also full throttle will break the ruway like tear it apart also usally less than 90n1

Thanks for admitting it ;)

Anymore to challange me and Tom? ;)

Also a 747 has a slower takeoff climb rate .
lol @ above post
