but A320s are also equipped with power transfer units. They sound a bit different than hydraulic pumps: like there is a dog barking continuously. We put on hydraulic pumps after we shut down one of the engines during taxiing. We do this to save fuel as it is more environmentally f...
For satellite Wi-Fi systems, an antenna is placed within a dome-shaped container on top of the airplane. Over time these antennas have been designed to be more aerodynamic to produce less drag and therefore use less fuel. Older antennas were required to face the direction of the signal and ...
1 Since this expense accounts for approximately 25% of operating costs, airlines have strong incentives to manage their fuel usage. However, carriers do not internalize a crucial externality generated by combustion of jet fuel: the contribution of the resulting greenhouse gas emissions (mainly CO2) ...
Digital technology at the service of the CNC machine In the 1960s and 1970s, the CNC machine took shape, thanks to digital technology that made the automation of production processes much more efficient. In 1957, the first CAM (Computer Aided Manufacturing) software, an NC programming tool cal...
extremely and intently focused on the procedures and operations, and doing the various countdowns. I honestly can’t remember that much about it but I do remember that at a certain point in the process, the Commander turned to me and said, “Hold on a minute and look out the window. ...
This makes it easier to see even if you are sitting on the aisle. New aircraft types like the Boeing 787 Dreamliner and Airbus A350 are built using lighter composite materials, which allow them to burn less fuel. They’re also better for your skin: Used mostly on international flights, ...
The great thing about summer holidays is that it’s warm and you really don’t need to pack much. Make a clothes plan before you go away and stick to it. Use a big fabric backpack (this is what I use) that you’ll be able to use for flights with even the crappest allowances. ...

“It’s there to to hold all of the wiring and pipework, as well as to contain the fan blades,” says McCree, pointing out a bare fan case with a carbon fiber top. The fan case has a “wet” side” and a “dry” side. The wet side is where the fuel and oil go and the ...
