Frequent flyers especially may be interested in the air they breathe while cruising at thirty-thousand feet… put it this way, there are all sorts of surprising ingredients, as it were, in the mix. And then this, an explanation of the low humidity environment of many aircraft cabins:
Most airplanes use about 50% recirculated air and about 50% bleed air that comes from the engines. Bleed air isn’t supposed to be dangerous. Outside air is first pulled into the first compartment of the engine, where it’s compressed and then pumped into the aircraft, sometimes through a filter. Then, it’s decompressed and mixed with the recirculated air before being blown out those little eyeball vents above your seat. The air is stagnant, and at about 12-percent humidity, it’s also drier than a desert. However, the air mixture is supposed to be safe.
An in-depth description of a flight from London to Tokyo, aboard a Boeing 747, written by British Airways pilot, Mark Vanhoenacker… that is quite possibly a more enjoyable experience than flying is, or has become.
It’s been dark for hours now. There are three pilots on a flight this long and now it’s time for my break. A colleague takes my place in the right-hand seat of the cockpit. Before I go to the bunk, located at the rear of the cockpit, I stay for a moment by one of the side windows, to gaze out and up. If you look into the night sky from an airplane for more than a few minutes you may well see a shooting star. My eye catches something. I look, smile and say to myself, There’s another one. I don’t even mention them to a colleague; another will be along soon enough.
The seat also features a fixed-back shell with a pan seat recline. This means you won’t feel the passenger behind you bumping or kicking your seat and, if you recline, the forward-sliding pan means you won’t be invading that person’s space.
As a bonus, the format also allows more seats to be fitted in an aircraft, surely making them a win for everyone. So, what are the chances of seeing these seats on flights any time soon?
Might this be a bucket list item? Visit fifty-two places across the globe, over the course of a year, while spending as close to week as is possible in each? Here are the fifty-two places. Now to find a round-the-world air ticket that makes it possible to visit all these places on the one trip…
In NSW, and I dare say in many other places, motorists are not permitted to handle their mobile phones whatsoever while they are driving. They are however able to pass their device to a passenger, but that’s about all. Needless to say taking Instagram photos is clearly out of the question.
Airline pilots appear to be bound by similar regulations, though as this collection of images goes to show, they don’t always seem to adhere to them, unless of course another crew member, someone who is non flight deck personnel, is actually taking the photos.
Perhaps airlines could consider assigning someone the role of flight photographer… many of these pictures, by sheer virtue of the circumstances in which they are taken, are stunning.
Despite incredible growth, airlines have not come close to returning the cost of capital, with profit margins of less than 1% on average over that period. In 2012 they made profits of only $4 for every passenger carried.
The engine information shown: On the top left are two dials; they indicate the N1 setting for the left and right engine. N1 is a measure of engine power – at 100% N1, the engine is producing maximum power (right now the engines are at 22.5% N1). The second row shows the engine’s EGT (exhaust gas temperature, currently 411°C), another measure of engine power and also an important thing to monitor – if the exhaust gas is too hot, you’re in trouble. To the right of the dials is a grid where engine warnings would pop up. On the bottom right are the fuel gauges; it shows the fuel in each of the three tanks and the total fuel onboard (40,200 gallons).
For a time I was living under one of the approach paths to London’s Heathrow airport. Jumbo jets lumbered overhead from early morning until the nightly curfew kicked in during the late evening. Yet we barely noticed them. Concorde, however, was another matter.
Apparently, Concorde “handled very well” and was easier to fly than other aircraft such as the Boeing 747. It is “a pilot’s plane, but also a passenger’s plane”, according to Andrew, and Concorde did turn out to be a favourite, at least for those who could afford it. Passengers may have enjoyed a choice of four different champagnes to wash down a sumptuous three-course meal, but if you think Concorde’s interior was the height of sophistication, think again. Compared to your average Airbus, Concorde was decidedly cramped.
Since I’m buzzing about the place at the moment… when it comes to avoiding delays while flying, especially domestically, taking flights that are scheduled for earlier in the day, rather than later, might be the way to go.
The later you leave, the greater the average delay you will face until around 6PM when things flatten out and 10PM when we see benefits in leaving later. It makes sense that delays increase as the day goes on because, we understand, the primary cause of delays is waiting for the plane to arrive from another city. The first flights out in the morning don’t have this problem.
Based on US research, but I imagine same principle applies elsewhere.
