here is my question... does every plane let out the fuel before landing or just in spacial cases?

Planes never dump fuel except in the most extreme of emergency situations. The only time it's done is if the aircraft is over-gross weight for landing AND must land immediately to preserve life.
Many large aircraft are overweight for landing when they take off. In most emergency situations they will fly around and burn off fuel until they achieve a safe landing weight. The only time dumping fuel is considered is when IMMEDIATE landing is imperative to preserve human life. Few emergency situations warrant that immediacy.

No. Some aircraft are certified with a landing weight that is less than the weight for take-off. That is mainly because the aircraft's landing gear is subjected to more stress on landing than on take-off. So if an aircraft takes off, with full fuel in the tanks & for safety reasons the pilot decides to discontinue the flight, & return to the point of departure. If the aircraft weighs more than the certificated landing weight then the pilot will need to lose the extra pounds before a landing can be safely carried out. One option would be to fly around until he has burned off enough fuel that the aircraft becomes light enough to land. But that isn't always good if time is of the essence, so he also has the option to dump fuel. This is only a good option in extreme emergencies because that fuel has to go somewhere after it leaves the aircraft. There are designated areas where fuel dumping is approved, so pilots of aircraft can't just go dumping fuel over any old place, such as a highly populated city.
Also not every aircraft has the ability to dump fuel from their tanks while in flight. This option is only provided by the manufacturer on aircraft that are designed to carry large amounts of passengers on long haul flights.

Airliners and some military aircraft are the only ones that can jetison fuel. This is an emergency procedure to reduce the landing weight of the aircraft. Many times the take off weight is higher than the landing weight. If an emergency that requires landing soon happens right after take off, the fuel might have to be jetisoned to get the weight down for safe landing. It is very rare that fuel would be jetisoned to lessen the chance of fire on landing, but it does happen. For that matter it is rare that fuel is ever jetisoned.

The only time that an aircraft will dump fuel prior to landing is in an emergency situation. This is to lesson the chance of a fire if the aircraft has to make a crash landing. They don't like to dump fuel - if it is able the aircraft will circle for awhile to burn off the fuel rather then having to dump.
Hope this helps!

Not sure exactly what you are asking but I will try. The fuel on board has weight. Depending upon the aircraft depends upon the weight it is able to land safely at. So depending upon how much fuel is put on board, depends upon what they must burn. If you are asking about fuel jettison.. most aircraft do not have this capability, and must then burn a % in order to be safe to land. I hope this answered your question.

You already have your answer but I just had to comment about the moron who said airplanes only take off with enough fuel to reach their destination. That is completely wrong and absurd... not to mention stupid. There is always enough fuel to make a diversion if necessary. There are extremely limited situations that call for fueling only to have enough to reach the destination, but the FAA requires at least enough fuel for an extra half hour of flight added onto the expected duration (at day) and 45 minutes extra at night.

i ask your self what type of airplane gasoline he offered, if it replaced into aviation gasoline the octane score is around the one hundred ten - a hundred and twenty section, regular motor vehicle gasoline is approximately 80 two-88. As his Vespa is in all risk a '2-stroke' engine, it in basic terms isn't equipped with a catalytic converter because of the fact the oil in the gasoline mixture would wreck it very without put off. the actuality that the cylinder compression is nowhere close to that required for aviation gasoline, most of the capability produced through the gasoline would be wasted, because of the fact the exhaust port on the engine would open on the same time as the main area of the charge continues to be increasing. this would supply very intense exhaust temperatures, the port factor of the piston would soften, with the resultant hearth being very stable for curing constipation. Admittedly, some overall performance boost would be realised for a quick term till the engine grenaded.

I am an aircraft mechanic. Fuel is only dumped in case of an emergency landing to lower the probability of a fire or explosion.

planes dump fuel only in the moment of emergency
