Hi Guys

I'm flying a 737 - 300.

Anyone any idea how to arm the spoilers. I'm totally lost.

Thanks

George

Normally you press shift & / - if not just go to your throttle quadrant, the lever is hanging around there somewhere

Hey Thanks Pearly

It's only easy if you know how.

there is another way too... all you have to do is press F2 to deploy them and F1 to retract them

That's for the thrust reversers, not the spoilers.

What do the spoilers do again? Embarassed (I know I could look up Wikipedia but a short description from anyone here would be great 😂 )

You want it short? Here you go:

Spoilers on ground reduce drag. Spoilers in the air (speed brakes) reduce speed.

Spoilers reduce lift.

Oh so spoilers in the air are called speedbrakes? Yeah, I can understand how they work, a little flap that pops up on the wing causes the air to catch onto it, and therefore "push" the plane backwards a bit, and therefore reduce speed.

But what I don't get is what Agus said about them reducing drag on the ground. Care to explain?

Thanks a lot!

Yep. Spoilers in the air are called speedbrakes.

I made a mistake in my previous post. Spoilers increase drag. It makes sense now.
If the spoilers decrease drag, the airplane will keep rolling on the runway. The spoilers decrease lift so that the wings can't lift the airplane keeping the airplane on the ground. Spoilers also make the brakes work efficiently.
Increasing the drag will slow the plane down.

Right so basically they do the same in the ground and in the air - slow the plane and make it more difficult for it to climb.

Thanks 🙂
