Any stroll by an airport reveals a bunch of operations that appear to make no sense. You’ll see passengers lining up for quarter-hour for safety after which needing to hurry on the finish to get their stuff into bins. Why not stretch out the world the place individuals fill these bins, eradicating that bottleneck? Or, you’ll see a bunch of pricy shops promoting purses and designer footwear, and roughly zero prospects are in there, as a result of nobody buys that stuff on the airport. Why not demolish all these and exchange them with non-public bedrooms to cater to younger lovers?
Different operations at airports have plenty of thought behind them. However these strategic ones is likely to be the silliest of all.
Shifting Numbers Round, As a result of the Earth Retains Shifting
Airports assign numbers to their runways, and so they choose these numbers utilizing a particular system. The runway’s quantity describes its route.
Let’s say, for instance, {that a} runway factors a tiny bit south of southeast, in order that it factors 140 levels from north. This runway might be known as Runway 14. Really, it is going to have two names as a result of if it factors 140 levels from north going a technique, it factors 320 levels from north going the opposite approach. The runway is subsequently named 14/32.
There’s only one drawback, although: North strikes.
The magnetic north pole can transfer 40 miles in a 12 months, and over time, meaning a runway that factors 140 levels won’t level that approach any longer. In 2019, the FAA ordered Wichita Eisenhower Nationwide Airport to rename its 14/32 runway to fifteen/33. The price of repainting this and their different runways? A whole lot of hundreds of {dollars}.
Hey, whenever you’re purchasing for new paint to fairly up your runway, you don’t need to skimp and purchase a budget stuff.
Scaring Birds with Tina Turner Songs
The best risk to an airport comes not from human terrorists however from avian terrorists. A busy airport would possibly see lots of of hen strikes a 12 months — “hen strikes,” in fact, being the official time period for when a hen strikes a airplane. Some hen strikes don’t have any consequence (for the airplane, even when it kills the hen). Different instances, a hen flies into an engine and the airplane comes crashing down.
The strongest protection towards birds? Killing them — with weapons. Airports have snipers dedicated to killing any geese that they spot flying in a suspicious method. Different airports make use of one thing known as acoustic deterrence. They play sounds that hold birds away. This works, not essentially by scaring birds away with noise however by disrupting their very own calls, holding them from convening. Right here’s a video of the system in motion:
You may need seen that that’s really a video of “The Finest” by Tina Turner. That’s as a result of one Gloucester airport found that their standard hen misery recordings weren’t working. The van broadcasting this music occurred to have a Tina Turner file helpful, so that they tried broadcasting that as a substitute. It labored, and the world was saved from birds — for now.
Blasting Runways to Cease Planes from Slipping Off
Each time a airplane lands, it leaves the runway in barely worse form for the airplane that follows. This isn’t as a result of the airplane erodes the tarmac. It’s as a result of the airplane deposits one thing. A bit little bit of rubber transfers from the airplane’s wheels to the bottom under every time.
So, a pair instances a 12 months, the airport has to scrape the runway with high-pressure water, to take away all that rubber residue. Considered one of these upkeep classes would possibly take away 100,000 sq. ft of rubber from a single runway.
With out this upkeep, airplanes danger slipping. The hazard is a bit more sophisticated than sliding on the rubber itself. As a substitute, the issue is {that a} runway coated in rubber received’t be capable to drain correctly. It would keep moist once we’d in any other case count on it to be dry, and the touchdown airplane received’t have sufficient traction.
Possibly this may lead the airplane to crash proper into the terminal. That might doubtless break individuals’s complete day.
Putting the Entire Factor on Balls
What occurs if a large earthquake strikes an airport? Arguably, an airplane could be the most secure place so that you can be in such circumstances. You’ll be able to take off, seconds earlier than the bottom beneath you crumbles. This was portrayed within the catastrophe movie 2012, launched in 2009, in addition to the catastrophe movie 2009, launched in 2012.
However that gives little consolation to the individuals contained in the airport’s buildings, who will nonetheless be dealing with doom. One resolution? Putting a whole terminal on a bunch of ball bearings, so just a little slipping and sliding within the bedrock under received’t rip the constructing aside in any respect.
The extra technical title for these bearings is friction pendulum seismic isolators. When San Francisco constructed their worldwide terminal a pair a long time in the past, they plopped it on 267 of those gizmos. If an 8.0 earthquake hits the town, the terminal might be positive. If a ten.0 earthquake hits, it received’t, however nothing else might be positive both, so let’s not hassle planning for that.
Burning Rubbish, for Cash
Let’s say you don’t end your salad on a airplane. The place do these leaves of lettuce go? In the event you’re touring internationally, don’t count on the airline to ship them to a landfill or a compost pile. You’re not supposed to hold any sort of plant or animal matter whenever you cross the border, as a result of that lifeless leaf would possibly simply set off the following invasive plague.
All trash from the airplane have to be incinerated. And that doesn’t imply the airline can simply pile a bunch of luggage of trash on a truck to go to some incinerator in the course of the town. That’s in all probability precisely what the psycho who dropped anthrax-cholera gum wrappers within the airplane needs the airline to do. No — for max security, all trash from this worldwide flight have to be burned within the airport itself. So, you possibly can count on the airport to have a large incinerator on the property, the place they will eliminate such rubbish (and eliminate passengers who argue with TSA brokers).
The airport fees the airline for this service. One airport in Wisconsin, for instance, will cost $125 for each small bag of rubbish it burns and double that for a big bag. Sadly, now that we’ve made this enterprise public, airways have one other expense they will complain about once they elevate fares. Once you ask for a charge breakdown in your subsequent ticket, count on a line merchandise labeled “incineration charge.”
