What's the minimum separation gap ?
 

What's the minimum separation gap between two aircrafts one is taking off another one is landing from behind ( on the same runway) In this video looks like they are close to each other or this is normal procedure ?https://www.youtube.com/watch?v=0Ahd9A_0Xxk

"Airplane take off SECONDS before another one lands on the same runway"
 

I suppose entitling your video "ATC doing their job" doesn't have quite the same ring to it. :O

There are a few controllers who frequent this forum, I'm sure one will be along shortly to give you a definitive answer.

In the meantime, if you click on "Show More" on the video page, you will see the statement "According to an air traffic control planes can use the same runway if the departing plane is airborne before the arriving plane touches down", though I suspect the correct answer is more about when an approaching aircraft can be given a landing clearance.

Thank you DaveReidUK. I would wait for a controller response

See my answer in your duplicate post!

As soon as the preceding departure aircraft's wheels leave the runway, the landing aircraft will be cleared to land (in EASA land anyway, the Americans do things differently).

Pistonprop I did not make a duplicate post ! Where I can find your answer ?

So ! I still did not get a clear answer
What's the minimum separation gap / safe distance between two aircrafts ?

There isn't one. It varies from airfield to airfield but you won't clear the departure to line up unless the arrival is a set distance from touchdown, eg 2 miles, then only if the departure advises he is ready for an immediate. There is no written minimum separation distance between arrival and departure. Separation is only lost if arrival and departure are on the runway at the same time or if a go around is mis managed

Minimum safe distance between airborne aircraft varies depending on airspace. 3nm in TMA, 5nm enroute, 10 mins in procedural for example...

Obviously was not Heathrow. The landing aircraft appears to be Ryanair who will avoid a go-around if at all possible.
As far as I can see it's good runway utilisation.

Not that close really, most airports I worked in UK operate that the landing aircraft not allowed to cross the start of runway(tarmac) before departed airborne. There are places that have a procedure of 'land after departing' where by landing aircraft can even be on same runway as long as pilot happy to provide visual separation. Radar separation is not used landing/departing as you work in a visual environment in VCR, this changes in low vis operations and then becomes dependant upon separation needed to clear Localiser/glide path sensitive area's.

Nothing much at all to see here....

Ops normal for single runway operation, thanks to the skill and expertise of UK ATCOs. 20 seconds lost there, probably even time for a quick crosser :E

Thank you all for your answers !

Loadsaroom!

Seriously absolutely no problem and as Talkdownman says should have got the tug across as well.

What a load of cobblers (and that's from a confirmed Ryanair disliker)

Some people have just never seen Heathrow on 23 in a very stiff south-westerly...

True. Mind you I have and it's entertaining timing the departure rolls on 27R against the inbounds. Mind you the EIN 737 captain was enjoying his visual...

Perhaps he was on a Middle Marker bet...

If you can get a fag paper between them they're not close enough!

<<it's entertaining timing the departure rolls on 27R >>

Do you not mean 09R against landers on 05?

Coming back to Gatwick on a fam flight once in a 737, we were a 4 miles on 08 and they still had time to launch 2 before we got landing clearance.
Are they allowed to do that nowadays with the new ANSP?
