you've never flown a plane before. What do you do next?

I'm at Virtual Aviation's million-pound simulator in Cambridge,

with Morag and Matt, and my job is simple.

Land the plane, and show you how to do it too.

You know, just in case.

And don't forget, this is part of Comic Relief's School of YouTube.

Everyone here's given their time for free to make this happen,

and we hope you learn something from it,

but remember we're doing this to raise money for children worldwide

who have limited or no access to educaiton at all.

Details of how you can help are on screen now,

and if you can donate, please do.

All right. Let's land this thing.

GORDON BURNS: "Tom, then, on his approach to London Heathrow Airport.

"Very strong crosswinds to contend with."

TOM: Whoa! Whoa, whoa, whoa, whoa, whoa...

GORDON BURNS: "So, wrestling a bit with the control column.

"Bringing it back to centre only stops the roll continuing,

"he needs to nudge it the other way to get on course.

TOM: I'm way too high. Pull the thrust ba--ack!

GORDON BURNS: "Swaying in the wind, and he reduces the thrust

"to get the nose down.

"But I think it's too much, he's coming in too low."

COMPUTER: Pull up!

TOM: I'm trying!

GORDON BURNS: "There's the warning system, ordering him to pull up,

"and he has got the nose back, but is it enough?

"Is he going to land short of that runway?

"He's almost down, he is short and veering left..."

TOM: That's technically on the runway!

GORDON BURNS: "Not on the runway, he's lucky there's no building there,

"but he's got a problem, he doesn't realise it, I don't think."

TOM: Why are... why are we not stopping?

GORDON BURNS: "But he has accidentally disabled the auto brake,

"so he's not going to stop."

TIM TAYLOR, INSTRUCTOR: "And we've crashed." (LAUGHTER)

GORDON BURNS: "But not a bad effort from Tom.

"Morag next. Can she do better?

"A set of lights next to the runway guide her on height.

"If they appear white, she knows she's too high. Red for too low.

"But she's struggling here with the crosswinds.

"Just needs to keep calm and nudge the 737 back on course, which she has done nicely.

"And she'll be guided by those dials on height and direction."

COMPUTER: Sink rate! (ALARM) Pull up!

GORDON BURNS: "She is correcting, correcting too much,

"she needs to pull up again.

"And now she's overdone that too, so she's very high now.

"With the runway ahead -- there it is, she's supposed to be down on that runway,

"so she's in trouble here, this plane is getting away from her at the moment,

"automatic emergency instructions getting a bit frantic with her now,

"we are on our way down and there's only one way this flight will finish,

"and it's not good.

"Finally, it's Matt at the controls,

"and looking good in these early stages.

"The flight director instrument showing him he is almost bang on the descent path."

MATT: Oh, hello! (LAUGHS)

GORDON BURNS: "And he needs to follow the small purple diamonds with the control column

"and that will keep him on course.

"And he is very much on course at the minute, using the thrust lever skilfully there

"to adjust his height. He's keeping calm.

"Just small inputs on the controls keeping him pretty much on line.

"And he's heading straight for that runway, he seems pleased at that,

"this is a really good approach, easy does it now,

"is he going to miss the runway, surely not, tilting left a bit... and...

"that was probably the wing clipping the runway, but he is down.

"And now on the rudder pedals to steer it back towards the runway.

"And that, Matt, was a very good effort.

"So at the end of the round, at the end of the contest,

"Matt is the clear winner."

MATT: I think I landed that!

TIM TAYLOR, INSTRUCTOR: Yeah, you did! That was the best one out of the lot.

MATT: Yaaaay!

TIM TAYLOR, INSTRUCTOR: You're the only one to have made touchdown on the runway.

(LAUGHTER)

TOM: If you're ever the only one who can land a plane, that is how you do it.

And if you've learned something, then please,

help someone who hasn't got that chance.

£5 could help a Zambian orphan go to school for a month

and get a meal every day there, perhaps the only meal that they'll get

Thank you to Virtual Aviation, thank you to Gordon Burns for the wonderful voiceover,

and thank you to Comic Relief for setting all this up.

That is how you land a plane in an emergency.
