how fast do planes hit the runway when landing?????(in vertical speed)?
I normally land 50fpm to a max of 300fpm and i am sure that they are soft.

how fast do they do it in real life???

BYE

Don't know about heavies but the idea on aircraft I've flown is not to hit the ground at all but touch down as lightly as possible. When it's done properly you don't feel the bump. A great feeling when it comes off. I'm sure it's the same for any aircraft.

PS. I don't how that relates to fpm as I've never looked at my instrument panel while landing.

Ah OK. I don't think you can aquaplane on grass.

Shows how out of date I am. Also how good the shock absorbers must be nowadays.

You just slide naturally...

...and you're quite right, I was talking about those silly concrete runways someone invented. Personally a proper aerodrome should have runways, but a nice big omni-directional grass field.

Well the thought is, you should stall onto the runway. Obviously this doesn't work for all airplanes.
Small planes, just get really low, let the speed slide off, it should settle pretty nicely into the runway.
With larger planes, suddenly it might be that you need to make it off on a certain taxiway, stop near your gate, or stop before the end of the runway, and a "firm" landing might become necessary. Normally though, at large airports (for example, when I take a 767 into DFW), it is standard to just glide along, the mains just a few feet off the runway, until the speed is so low the tail will drag if we don't touch down soon, then lightly allow the plane to sink down. Done correctly, no violent bump, and if you have a long enough runway, reverse not needed. Not hard to use more runway floating along killing speed than actually stopping on the tarmac if you have the space. Traffic can create problems though.

If those are flare angles... then wow!

The landing procedure for delta-winged aircraft is completely different from conventional aircraft. The high angle of attack is necessary to keep the speed down. Delta wings are very stable at slow speeds & high angles of attack & will not stall in the usual sense. The Concorde had no flaps & I'm not sure it has airbrakes. The Vulcan has airbrakes (not sure about flaps) but unlike the Concorde normally deploys a braking chute after touching down.

I read an interesting article on flying the Vulcan some years ago. The author said that when landing it was like no other aircraft. You throw the book out of the window & start learning all over again.

Concordes engines came within inches of the ground on landing and takeoff however those who are observant will notice the small wheel on the tail, that was used incase someone thought they were in a fighter aircraft and pulled up a little to hard, thus saving the engines. The higher angle also worked as a speed brake when landing.
