how much time has to wait another plane to fly in the same rout as a Boeing 747,or the new Airbus?

Question

hoy many minutes does it have to wait to fly there, but without crashing because of the turbulence generated by the other plane before?

Answer 1

Wing tip turbulence goes out and down. If the same flight path is higher, time would not be an issue, if the flight path is lower, then a few minutes would be needed.

Answer 2

There is a Hangliding & Paragliding site, under the approach to Manchester airport in England.

It can be extremely dangerous to fly as much as several miles behind a 747 - it can take a stable paraglider & wrap it up into the proverbial "bag of laundry" (that's what hanglider piltos call it) & throw it at the ground.

Great flying site.....apart from that.

When Flight AA587 crashed in Queens, that was an A300 rather than the new Airbus. But the complexity of the problem, indicates that controlling turbulence needed improvements.

Answer 3

As it From Air Law for A/C seperation the basic standard in Croosing track case is 15 min.
OR
10 min incase both A/C using NAV AIDS
OR
5 min in case the head A/C is 37 KM/H (20 KT) or more faster
OR
3 min in case the head A/C is 74 KM/H (40 KT) or more faster

for Taking off there is a guide table shows 3 types of aircraft depending on there wights :
Heavy (H) all A/C types of 136,000 kg or more (like Boing 747 & the new AIRBUS 380)

Medium(M) all A/C types less than 136,000 kg but more than 7000 kg

Light(L) all A/C types of 7000 kg or less.

Now : '' seperation minima "

Arriving A/C : (for time approaches)
(M) behind (H) - 2 min
(L) behind (H) or (M) 3 min

Departing A/C :
a minimum of 2 min seperation is applied between (L) or (M) taking off behind (H)

Answer 5

As a pilot, you should wait 3 min for everything to die down. however, you can also fly above the turbulence even if it hasnt been 3 min. you cant fly below the turbulence though because all the downwash sinks to the ground and it is dangerous to fly throught that. but typically, 3 min.

Answer 6

A plane's wake is like a boats. After about a minute or so, all is well. The turbulence disapates quickly.

Answer 7

2-5 minutes depending on the size of the aircraft...
Widebodys creating a larger vortex which can cause a smaller
aircraft great promblems... It is a issue being researched for very busy airports...
