Gradual relocation essentially mean having to staff and equip nearly two full airports during the transition period. It is also annoying for the travelers that want to transfer planes and need to relocate to the other airport. They would then need to get transported to or from the new location and through security again unless a small short hop flight is ...

As an aircraft mechanic at a major airline, I think I can answer this pretty well. It wouldn’t be hard at all. All I have to do is wait for an aircraft move. This could be to bring a plane into the hangar or just to move it from one gate to another. I could simply volunteer to taxi the aircraft, which wouldn’t be unusual at all. At my airport, we have to ...

It allows them to do a run-up test of the engines without blowing debris at other parked aircraft, people, or things on the ground. [Credit to Ralph J] The walls have a structure that allows the noise of engine run-ups to be absorbed as well. Engine run-ups, especially multi-engine run ups, can be very loud. You can read more about IAC-Acoustics ground ...

Building an airport is a very expensive endeavor and usually involves government subsidies or is completely done by the local government. In recent decades, most government owned airports in Europe have however been transformed into companies that both own and operate the airport, usually with the government as initial owner of this company. Since this ...

It's likely to be a flare / flash bang for bird control. Schiphol uses these (amongst a wide variety of methods). Bird dispersal equipment There are various resources a bird controller can use to keep birds away from the runways. Standard equipment includes a flare gun with noise blanks, a bird alarm call system and a green laser. The ...

Moving airline by airline doesn't help that much: You still have the same chaos, just on a per-airline basis. The airports you mention are dominated by large carriers that have turned them into hubs (Turkish Airlines and Lufthansa). Even if you move all the other airlines one by one, you still have much of the pain of the big move when you move the largest ...

The main example in the question body is to confine the wing from the main taxiway, which runs across the bottom of the image. It may not seem like it, but a 50 m (164 ft) wide plane like those tankers parked at a 45-degree angle saves ~15 m (approx. one-third of its wingspan). The reference used by the USAF is AFMAN 32-1084 (PDF), from which: 2.1.5.4.1....

Gradually moving between airports is a living nightmare for connecting travelers. Exactly that was done at Montreal Mirabel airport, a fabulous, spacious new replacement airport for Montreal Dorval (Trudeau). Montreal used to be Canada's main international hub. International flights were banned from the old airport, as incentive for airlines to move all ...

A lot depends on whether the reject happened during the high energy or low energy phase of the takeoff. The boundary between the two is the reason for the speed call "xx knots", usually 80 knots or 90 knots, during the takeoff roll. There will be specific procedures to follow following a reject, depending on the airplane and the airline's own procedures. ...

That's a countdown to the Target Off-Block Time (TOBT) showing 67 minutes to go. The minus is like the T minus 5 for a rocket launch. [TOBT is the] time that an Aircraft Operator (AO) or Ground Handler (GH) estimates that an aircraft will be ready, all doors closed, boarding bridge removed, push back vehicle available and ready to start up / push back ...

Likely a flash-bang for runway bird control. Birds on and near the runway are an ongoing major safety problem (witness the "Miracle on the Hudson", an A320 brought down by a flock of geese shutting down both engines). Measures to convince them to go elsewhere are only ever temporary and of limited effectiveness. One of the measures that is commonly used ...

Those are hardened aircraft shelters, and each hangar is flanked by two blast walls (revetment). Those are for combat aircraft (the airport is mixed-use: public/military). Since in that hemisphere the sun is to the south, the shadows tell us they are not sunken structures, i.e. the hangars and walls are higher than the taxiways. The numerous taxiways are ...

Where I work, we have to stay in the tower for 15 minutes after the last departure in case they need to return. To my knowledge, there are no international regulations about this, so the rules may well be different from place to place.

London Heathrow (LHR) is owned by a private company, Heathrow Airport Holdings. I'm sure there are many other examples around the world.

did Kai Tak have a straight-in approach to runway 13 for use by steep-approach-certified aircraft? During the 1990s I regularly flew the Hong Kong IGS approach in 747s. At that time, to the best of my knowledge, there was no straight-in approach to runway 13. only the best of the best pilots were allowed to shoot the bent approach to runway 13, and only ...

Not just departures. Assume an emergency takes place en route, and that airport with the closed runway is the only one available within a big area. What now? There are two things to distinguish: Operating hours Temporary surface (runway) closure If the airport is already 24/7, the tower will remain staffed. If not, once the airport closes on schedule, ...

ATC can not only ask for a minimum speed, but rather instruct each aircraft to (more or less) exactly fly at a particular speed. This is essential for maintaining separation. As J. Hougaard pointed out in the comments, the speed on the last 4 NM is always up to the pilot to slow down to final approach speed. It is the duty of the pilot to evaluate if it is ...

Why bus The typical reason you use a bus to your low-cost carrier (LCC) or regional jet is the cheaper 'remote stands'. But this doesn't mean the stand is necessarily closer to the runway where the planes take off and land. See: Who decides whether an airline docks at a jetbridge or parks at a remote stand? Can't be too close A big area around the runway ...

To add to ymb1's answer about the -67, the other information on the sign indicates whether the flight will be arriving or departing (in or out), the flight number (2110), departure/destination airport (PSC), and scheduled time (10:00).

I believe there are quite a few misconceptions here: When an aircraft is "pressurised", it means that at higher altitudes, the pressure inside the aircraft is higher than the pressure outside. At lower altitudes, the pressure is exactly the same inside and out. Originally, aircraft weren't pressurised, and at higher altitudes the low pressure is a problem ...

This answer varies wildly depending on the size and type of aircraft involved, but in general: How is the runway cleared? They remove the aircraft, then sweep the runway for smaller debris and then inspect the tarmac to make sure the aircraft didn't gouge into it, and tear up chunks. Is the plane towed away (scraping along the ground)? No. The aircraft ...

You can probably guess - none. Like most industries, aviation relies on an assumption of good faith from the employees. The incessant string of terrorist attacks throughout this century changed some things, but the focus is squarely on protecting commercial flights with passengers aboard. Traditionally, the protection against joyrides was that a civilian ...

It looks like the reason for the Rwy 6 departure was noise abatement. The climb gradient from 6 is not as steep as for 24. The Jeppesen charts state the requirements: And it states that if you are unable to comply with the steeper noise abatement climb gradient for rwy 24 (583 ft climb per nautical mile), you should request 6 (300 ft climb per nautical mile)...

Approaches into Schiphol are usually vectored by ATC during the day (see below for night operations). This means the controllers are giving instructions to pilots depending on the current traffic, which makes it hard to say when exactly planes will overfly Egmond aan Zee. If the Polderbaan (runway 18R/36L) is used for landing from the North (18R), planes ...

Ground crew are typically employed by a handling agency, which is a company dedicated to performing ground handling of aircraft (exactly the things you describe). Some airports have several different handling agencies. Have you ever noticed, when waiting for your luggage to arrive at an airport, that there are several different help desks to choose from, ...

This is at Sea-Tac Airport in Seattle. The -67 indicates that the flight is supposed to depart in 67 minutes, and gives flight info like flight number, destination, and updated departure time. This is used more for the ground staff. Everything works on a timeline. At Horizon air, where this is pictured, the process usually begins at 40 minutes prior to ...

The major Australian airports were all privatized from the late 1990's. Smaller regional airports are still usually council-owned and operated.

Depends why the takeoff was aborted. Maybe it was a minor technical issue that the pilots can fix right away, in which case they may be allowed to just stay on the runway for a few seconds and then start the takeoff again. Or maybe there was a significant issue with the aircraft, which would require the aircraft to return to the gate to get fixed by a ...

I know that KAVX has quite a hump in the middle of the runway which does not allow for departing aircraft to see all the way down the runway, and I'd imagine that the procedures are the same as they would be for Elk City Airport. The Facilities Directory/Chart Supplement for KAVX says: PILOTS CANNOT SEE ACFT ON OPPOSITE ENDS OF RWY DUE TO GRADIENT, MUST ...

I read this as "there is a place to park your plane for a while and tie it down if you are so inclined." I do not expect the airport to provide the chains or ropes. Some will, but small town or village airports are barely maintained and nobody is thinking about how to make life better for transient airplane owners. If you intend to park and ...
