The price of jet fuel as of January 2022 is as follows: $2.46 (US dollars) per Gallon. 1 litre = 0.65 pence (pound sterling)
A 747 can seat 380 to 560 people, depending on how an airline sets it up. A full one is a moneymaker. But an airline that can't fill all the seats has to spread the cost of 63,000 gallons of jet fuel — roughly $200,000 — among fewer passengers.
Jet fuel costs anywhere between $500 to $2,000 per hour on average. The exact cost depends on the type and size of aircraft it's being purchased for and the type of fuel being purchased.
The reason behind ATF price being lower than that of petrol and diesel is the way tax on these fuels are calculated. Just like the conventional vehicle fuels, ATF too attracts both central and state taxes, and it varies from state to state due to different VAT rates.
How far can an airplane go on a full tank of fuel without stopping while travelling at a constant 15,000 feet above sea level? A: This depends on the size of the plane, its efficiency, and how fast it's flying. A modern Boeing 747 can fly about 15,000 km (9,500 miles) when it's flying at 900 kmh (550 mph).
Even so, the typical range on a single tank of fuel for a private jet are typically about 1,500 miles for small aircraft. In most cases, this is enough to carry passengers to major destinations in the continental US without having to refuel.
The reason to dump fuel is simple: to drop weight. Any given aircraft has a Maximum Landing Weight (MLW) at which it can land, and in most cases that weight is lower than its Maximum Takeoff Weight (MTOW).
Planes continue to glide for long distances even after running out of fuel. At some point, though, the fuel would have run out. An aviation expert said most new-generation aeroplanes would continue to glide, even after all the plane's fuel reserves had been exhausted.
For a pilot, there is no such thing as too much fuel, but for the airline accountants, there certainly is. Conversely, there is obviously such a thing as too little fuel.
A typical takeoff speed for a Boeing 747 is around 160 knots (184 mph), depending on the jet's wing flap configuration, the number of passengers aboard, and the weight of their luggage, fuel load, current weather conditions, and other factors.
A passenger jet could glide for up to about 60 miles if it suffers a total engine failure at its cruising altitude.
In the May 2020 report, the Bureau of Labor Statistics reports the range of salaries for airline pilots, copilots, and flight engineers from less than $80,920 a year, to the highest 10 percent earning more than $208,000.
Instead, pilots are paid per flight hour. Meaning a pilot is only paid while their airplane is running. As of May 2021, the median annual earnings for airline pilots was $202,180. But if you're researching this as a possible career there is a lot more to consider than just the national average.
The pilot can sleep for no more than 40 minutes, and must wake up at least half an hour before the descent for landing. They get the first 15 minutes after the nap to fully awaken, during which they can't resume actually flying the plane, unless they need to help deal with an emergency.
Pilots don't earn a flat annual salary like some professions. Instead, they're paid an hourly wage for each flight hour flown, along with per diem. Most airlines guarantee a minimum number of hours per month, so that pilots can count on at least a minimum amount of monthly income.
While landing, speed is largely affected by the aircrafts current weight, commercial airplanes typically land between 130 and 160 mph (112 to 156 knots).
In addition to wing spoilers, airplanes use disc brakes. Airplane disc brakes are similar to the braking system in automobiles. They consist of a pair of calipers that, when engaged, squeeze pads against the rotors of an airplane's landing gear. Disc brakes are designed to remain static at all times.
Technically this is the so-called 'stall speed', where air passes over the wings fast enough to sustain altitude, and for small planes this can be less than 50km/h (31mph).
Most airlines will work the total fuel required, which is presented to the pilots, through their flight planning system. The pilots will then make a decision as to whether they require any 'extra' fuel.
Fuel dumping (or a fuel jettison) is a procedure used by aircraft in certain emergency situations before a return to the airport shortly after takeoff, or before landing short of the intended destination (emergency landing) to reduce the aircraft's weight.
