How Fuel Efficient Is An Airplane ?

How much fuel does a 747 need to complete an international flight? How efficient are these aircraft? Join Cristen as she asks how much fuel an international flight actually uses.

How do they measure ?

Aircraft must consume fuel to supply the energy needed to move the vehicles and their passengers. Fuel economy is a measure of how much fuel an aircraft needs in order to operate, and it can be expressed in several ways,

for example by the liters of fuel consumed per passenger per kilometer. Aerodynamic drag, which exerts a force on the aircraft in the opposite direction from the velocity, is a principal determinant of energy consumption in aircraft because they operate at such high speeds.

Airbus Plans Cockpit Toilet to Make Single-Pilot Operations a Reality

In a bold move aimed at cutting costs, Airbus is exploring the possibility of installing a potty-style toilet right behind the Captain’s seat on its A350 long-haul aircraft. According to the reports from paddleyourownkanoo.com

This proposal is part of the ongoing effort to implement Extended Minimum Crew Operations (eMCO), a concept that could revolutionize the aviation industry by reducing the number of pilots required on ultra-long-haul flights.

Currently, on long flights, two pilots stay in the cockpit while the others rest in a separate compartment. However, under eMCO, one pilot could be alone in the cockpit for up to three hours while the other sleeps. The goal is to reduce crew costs and improve airline efficiency, as fewer pilots would be needed for these flights.

But this proposal has raised concerns from pilot unions, who worry about safety and the challenges of single-pilot operations. To address the issue of bathroom breaks, Airbus suggests installing a radio-equipped toilet in the cockpit, allowing the pilot to use it without leaving their seat.

If the pilot needs to use the toilet, the second pilot would have to be woken up, terminating the eMCO process temporarily.

If successful, Airbus plans to begin testing this system on its A350 aircraft as soon as 2027, with single-pilot operations possibly being introduced on freighter Airbus A320s within the next five years.
