Yes, a lot safer than trying to land heavy.
In general: no, not on a normal flight. Any fuel "left over" in the tanks will be used for the next flight. Airliners only dump fuel when they are too heavy to make a safe landing - and this situation only occurs when the landing happens much earlier than planned, such as a diversion or an emergency landing. Not all commercial airliners can dump fuel, some have no option but flying around for a while to "burn off" fuel before being light enough to make the above-mentioned early landing.
It is possible to dump fuel from some commercial aircraft. This is only done during emergency procedures to get the aircraft under a safe landing weight. The brown spots are not jet fuel, airline would not dump fuel unless it was a definite emergency. As we all know fuel is expensive and airlines cannot afford to just dump the fuel. The spots are possibly acid rain or tree particulate. If this is something that you must solve, I would look for a more simple answer.
Depends on the amount of fuel. Every plane has a different maximum landing weight. Fuel is very heavy stuff - usually almost half a jet's weight on takeoff. Commercial flights are calculated so that by the time the jet gets to its destination, its weight has been reduced by the burning of this fuel, and it is perfectly safe to land. In an emergency, though, if an incident happens just after takeoff, a plane may have to make a fast return to its departure airport. However, it is still full of the fuel for its planned flight, and therefore over its max landing weight. If the plane is still flyable, the pilot will perform multiple spiralling descending circles, burning as much fuel as possible until it is safe to land. The pilot can also physically open the fuel tanks and dump his fuel out the back.
No, it is not safe to dump grease down the drain as it can cause clogs and damage to the plumbing system.
We would need to know what size or model plane you are asking about. They are located under the fuel cells, if they have them. Not all planes can dump fuel.
no it is not safe to dump MgI2 down the drain because it will eat away the material and other compounds in your drain.
Most larger trucks burn diesel fuel.
yes there are helicopters which can dump fuel. the most basic helicopter allouette ( the french single engine helicopter) has a capability of jettisoning fuel at the rate of 130 lts per hr.
Bon voyage...have a safe flight..
No.
Perform safety checks, fuel checks, and flight plan review as part of the pre-departure checklist to ensure a safe and organized flight.
The weight of jet fuel is calculated primarily for safety and performance reasons. Knowing the weight helps ensure that the aircraft remains within its maximum takeoff weight limits, which is crucial for safe flight operations. Additionally, accurate fuel weight calculations are essential for fuel management, flight planning, and optimizing fuel efficiency during a flight. This information also assists in determining the aircraft's center of gravity, impacting stability and handling characteristics.
