jet-planes-waiting-in-the-air-to-be-refuelled-javascript Planes were seen waiting on the tarmac to be refuelled yesterday after a power cut. Many passengers leaving and arriving in Manchester were affected. The statement read: 'Engineers have now resolved the power issue which affected the fuel supply.  But a spokeswoman for the airport said although the check-in terminals were affected earlier in the day by the power outage, this was resolved soon after the problem began. Chris Wild, a passenger waiting to leave the airport, wrote: 'Manchester airport facing delays due to power loss preventing refueling from fuel hydrants. If anyone traveling prepare for delays. A small tanker having to refuel one by one going back to refill after each plane. Check in systems also down.'. If you are refueling at the station, there are volatile fumes escaping from the pump. You add those fumes in with a hot car exhaust or shitty car that could potentially have say a bad wire some where that is arcing, and now you have recipe for distaster. permalink.  Race cars dont get turned off while refueling quite frequently, though some series require the car be turned off in the rules. permalink. embed. Mid-way refueling seems like it would be a Good Idea™ at that point. Of course, landing would add a heck of a lot of time to the flight, so it seems the better option would be mid-air refueling. It would allow for the aircraft to be more efficient, without the need for stopping on a long journey. Boeing and Airbus both make a few airplanes | that can do | mid-air refueling, in fact one of them is a highly modified (properly called a VC) used as Air Force One: (source: www.- ). I assume that, because Airbus and Boeing's engineers and sales managers are really quite smart.

Right now if an airliner wants to fly a really long distance eg. This, of course, makes the flight of the aircraft less efficient than it could be 1. Thus, if the craft could theoretically carry half as much fuel, that should increase the fuel efficiency of the craft, right? Of course, landing would add a heck of a lot of time to the flight, so it seems the better option would be jwt refueling. It would allow for the aircraft to be more efficient, without the need for stopping on a long journey.

Boeing and Airbus both make a few airplanes that can do mid-air plaesin fact one of them javascriph a highly modified properly called a VC used as Air Force One:. But I'm not sure what that reason is. Less fuel would mean less induced drag or, if mid-air refueling were common practice, a wing that was designed to be more efficient because it was required to handle less weight.

Fuel Quantity Unlike smaller fighter jets, you would need to offload a substantial javasfript of fuel. For a B, you're looking in the range of 60 tto of fuel for half a tank. The boom of a KC faster than a basket can do around 3 tonnes a minute. The math comes to then 20 minutes of aerial refuelling. The KC can do perhaps tonnes, so you might squeeze out three refuelling operations from one flight. Risk This is considerably more dangerous than the very conservative safety margins aircraft normally operate within.

A quick search on YouTube is enough to propose this entire thing is very dangerous. Furthermore, you need to consider that the aircraft needs safety margin planess divert should refuelling not work, which cuts into the benefits you can expect.

Refuelling Area Javsscript at the route jft proposed, ket closest airfield would probably be in Alaska, at least km away. Even if you did reroute, you'd get away from the jetstreams that aircraft over the Pacific use lying considerably further south, reducing efficiency.

The same scenario plqnes for jet planes waiting in the air to be refuelled javascript Atlantic flights. The receiving aircraft crew would also need special training. The airframe modifications would be complicated and require certification. Furthermore, you would need to get everybody to agree on some common standard. Logistics Planning is difficult. Each aircraft would have to be rerouted to intercept the tanker at a certain time and place. You want to refuel them perfectly one after an other, which is plaanes certainly not possible.

There's just not the volume of aircraft movements feasible for this, especially for the ultra-long flights where it may have the greatest benefit. Other Landing Benefits Include changing crews and possibly offloading passengers. Applicability Javasceipt number of thw where this can be practically implemented and used is very limited and for lpanes intents refuelped purposes, you can just land the plane itself and refuel it. Even for the route you propose, it's around 7, km which is not a lot for a B Don't look at the fuel consumption of the airline flight in isolation.

An airline would need to combine the fuel used by both the revenue-earning flight and the tanker, and then add the cost of operating it, too. Even if this could be shared by four or five revenue-earning flights, the total would still be worse.

To waitingg out how big the jet planes waiting in the air to be refuelled javascript saving by in-air refueling is, the Breguet equation is your friend. The saving fuel equivalent to 2. Add more if the tanker needs to do even as planws as to take off, let alone fly to a refueling point and wait there. And the fuel saving needs not only to pay for the tanker's fuel needs, but also for its crew, maintenance and depreciation.

Aerial refueling is a great technology to make complex military scenarios possiblebut is a very ressources-hungry beast. See wayback machine here :. Here is part of the abstract from a paper describing their approach:. In this paper it will be described how the safety of air-to-air refuelling has been assessed, and how proposed new or amended regulations and acceptable means of compliance have been defined.

In their papers, you jet planes waiting in the air to be refuelled javascript find data for which flights mid air refuelling is worth it, how they want to make it happen, met some interesting facts.

Jay Carr Jay Carr Witing as the way the military uses them Actually if you have a moment to describe the difference in mission ie. Especially since you know directly :. Aerial refueling aid a very expensive endeavor with very few practical uses.

For the military, the increased price of fuel is well worth the increased tactical ability our aircraft receive. Whether that's playtime in a kill box, or blue water operations in the Navy ie, no divert, where the carrier is the only option and being low on fuel requires a tankerthere are a myriad of tactical and administrative benefits the military pays for through jet planes waiting in the air to be refuelled javascript refueling.

I'll post an actual answer later when I've got a bit more time. ATC exists expressly to keep airliners apart, putting two very large aircraft in close proximity, 10's of recuelled separationone carrying an enormous fuel load and one carrying human cargo, is a recipe for disastrous inattention.

To put it another way, there is probably not enough economic benefit, and the solution to "not enough range" for commercial aircraft seems hhe addressed by increasing fuel capacity or making ajvascript stops. Bear Jet Planes Waiting In The Air To Be Refuelled Time in mind that military and civilian aviation operate under different economic, safety, and logistical priorities, so what's good for one may not be for the other.

Improve this answer. Thunderstrike Thunderstrike I can remember when all the records for "least unscheduled maintenance," "lowest IFSD rates," etc on aif B were held by Icelandair. Javasccript only problem is the occasional volcanic ash cloud. Greenland, being mostly 9, ft mountains, is a different story, of course. Eight hours is a long time I would say too long to be cooped up in an economy inn, and there are airliners already in revenue service capable of significantly longer flights.

IMHO a more passenger-friendly way to go further in a single hop would be to go faster rather than stay up longer. Show 8 more comments. If the airliner has to descend to meet the tanker, that's yet more wasted fuel. Like a B, or A? Maybe even a CR? Then you could have one tanker carrying fuel for several planes. Granted this doesn't address a whole list of other problems but Jet planes waiting in the air to be refuelled javascript we save not just some fuel, but make flights possible which could not be flown before.

However, smaller planes are less efficient, and more cramped on the inside. The seat-mile jet planes waiting in the air to be refuelled javascript consumption would be larger, and I certainly will not look forward to flying transcontinental flights in a CR!

Bigger than I would have expected, but I doubt big enough to justify the cost of a second aircraft. That's 2, tanker flights until jet planes waiting in the air to be refuelled javascript. But that's before you have any people javasccript fly or care for the tanker. Even assuming a waitinf world, that's many thousands of trips for the tanker before break-even. The world is not perfect.

But when I see a joined wing proposal, I know this is from an academic ivory tower with little practical experience in aircraft design and construction.
