Landing Of Taking Off?

Sat Aug 21, 2004 6:32 am


Sorry if this too obvious for some of you, but is this 330 landing or taking off?

I say it is taking off. No flaps, spoilers, or engine reverse thrust.

Looks like a take-off to me.

Flap configuration and lack of tire smoke are my biggest clues.

Most airplanes don't even have spoilers.

Its a T/O with out a doubt. you can just tell with the blured back ground which indicates high speed.

also the main gear is just lifting. if it was a landing there would have been smoke.

It is a landing - Hey, someone's gotta oppose a posting in every thread! And I think it is a Boeing, not an Airbus  Big grin

Most planes don't have spoilers.

Most jets with spoilers are restricted from using these as airbrakes when the flaps are deployed beyond the first two settings. Spoilers AND flaps/slats deployed on final approach is a good way to get yourself into trouble at low speeds since you run the risk of stalling the wing.

So yes, landings without spoilers are quite possible. After touchdown, most aircraft with spoilers will deploy these (automatically) to make sure the wings lose lift.

Flap settings make it look like takeoff.

Landing without spoilers is definetly possible, they are just used because when yer in something the size of a jetliner zipping along at those speeds when it comes time to stop the thing it never hurts to be able to pull a little handle and the wings magically loose lift while at the same time causing more drag than ussual.

and...

A little clarification needed, I think. Spoilers are used after touchdown to force more weight onto the gear for braking, not for any other reason. It adds downforce to the airplane the same way a spoiler on a car does. It's not about drag (deploying spoilers alone is not going to do a thing to stop an airplane on the ground) and while it's technically about lift, it sounds misleading to say you'd deploy them "to make sure the wings lose lift" because it's not as if you're trying to prevent some sort of inadvertant takeoff, you're just trying to kill the lift so as much of the airplane's weight as possible reaches the landing gear to assist in braking.

But yeah, this is a takeoff anyway.

Spoilers are used after touchdown to force more weight onto the gear for braking, not for any other reason.

They do this by killing approx 80% of the lift produced by the wings/flaps and more than doubling the drag, however, so what Starlionblue and CanadianNorth said is actually spot on.

because it's not as if you're trying to prevent some sort of inadvertant takeoff

Actually that's exactly one of their purposes. Once you've hit the tarmac, you want the aircraft to stay there.

Cheers,

Jeff
