Where can planes dump fuel?

Hello.
I have a question can planes dump fuel over the land? Does this fuel land on the Earth?

You can dump fuel wherever. You just need to be over 7000 AGL. (Above Ground Level)

Does fuel evaporate in the air?

You could say that. It has no effect against the terrain or air.

Above 7000AGL ang your plane weight is not below the max landing weight.

In real life we can only dump 6000 feet AGL. Air traffic control will have designated points for dumping fuel.

We talk to them, advice when we start the dump and when we finish. All the fuel will evaporate into the atmosphere. Not the most environmental friendly thing but for sure a big safety thing to dump fuel.

Just to dovetail in the discussion with Aernout’s comment. This was a video of an incident with a Delta 777 at Atlanta. At 6:30 you can see the FL of the aircraft and there’s some radio communications included.

Dumping fuel in the ground toxic ? U think it evaporates

I think a lot of regions have their designated points for fuel dumping over water though. A lot of flight incidents tend to go along those lines and listening to communications is a good indicator.

So the Flight Crew will inform ATC that they have to dump fuel. ATC should then coordinate with the flight crew the following:

a) the route to be flown, which, if possible, should be
clear of cities and towns, preferably over water and
away from areas where thunderstorms have been
reported or are expected;
b) the level to be used, which should be not less than
1 800 m (6 000 ft); and
c) the duration of the fuel dumping.

Other traffic should then be separated from the aircraft
dumping fuel by:

a) at least 10 NM horizontally, but not behind
the aircraft dumping fuel;
b) vertical separation if behind the aircraft dumping fuel
within 15 minutes flying time or a distance of 50 NM by;

  1. at least 1 000 ft if above the aircraft
    dumping fuel; and
  2. at least 3 000 ft if below the aircraft
    dumping fuel.

Adjacent ATC control sectors will be informed of the fuel dumping taking place
and broadcast an appropriate warning message for other traffic to remain clear
of the area concerned.

At our airline we have to maintain radio silence during the fuel dumping operation and ATC will be informed before the fuel dump about the time when radio silence will terminate.

There are specific points in the airport charts or airspace procedures designated for this type of events, and the fuel disipates before reaching land.
