Since the 1960's and 1970's when political hijackings were a problem, airplanes started to only carry the fuel required for the flight. This means a typical fuel load will be something on the order of: taxi fuel at the departure airport fuel to fly and land at the destination at a given altitude and forecast winds if an alternate is needed: fuel to fly to ...

There are several reasons why it is hard to support multiple booms on a single tanker: 1) Booms need an operator who is located in the fuselage. Video systems provide for remote control on newer tankers, but older ones still use direct view or looking straight down the boom at the refueling point in the receiving aircraft. 2) The boom is physically large. ...

Both the KC-135 and KC-10 can burn the fuel it carries on board for refueling (the notable exception was the KC-135Q, which carried separate tanks of JP-7 for the SR-71 Blackbird). Both indeed do have significant fuselage tanks - the KC-10 is notable for being 'dual-mission' capable, meaning it can carry both fuel and cargo, and the KC-10 is also air-...

The stall speed is around 95-100 knots for the older F variant, and something like 90-95 knots for the newer J variants. A KC-130 can refuel between around 100 and 270 knots. The lower end of this is well within the maximum speed of many military helicopters, eg the Pave Hawk, Black Hawk, Chinoook or Sea Stallion. That leaves an "overlap" of around 20-40 ...

Tankering fuel means that an aircraft carries more fuel than required for the flight to the destination, because difference in fuel price at airports makes this operation less expensive than natural refueling at destination. Wikipedia: Tankering fuel When fuel prices differ between airports, it might be worth putting in more fuel where it is cheap,...

The problem isn't the relief of stress from dumping of loads. If it was, you would have the same failures happening because of the act of landing, where the wing goes from being heavily loaded to unloaded in about the same amount of time. And it's once per flight in any case and is something that all airplanes have to cope with. Fatigue is all about the ...

Those two locations you circled out are the under-wing refuelling pods, mounted on pylons (where, I suspect, the A340 outboard engines would be). You can find a picture of them on the A330 MRTT Wikipedia entry, under the Design section. And those propellers on the pods are likely the ram air turbines that power the refuelling pods, according to the ...

When I was flying the KC-135 tankers - A model and Q models - all crew members had parachutes, and all parachute packs had supplemental oxygen bottles that were good for at least 10 minutes - which was enough time to descend to the point where you did not need supplemental oxygen. If you had to bail out, it would be through the crew entry hatch, on the port ...

Sounds like it may have been a Boeing RC-135 (source) No windows and a flat grey color would lend to either a cargo aircraft or a military aircraft with military being likely considering the color choice.

The Dutch defence department website has the answer: motoren: 3 maal CF6-50C2 turbofan Which translates to engines: 3 times CF6-50C2 turbofan

Can Russian-built tankers refuel NATO probe-and-drogue receivers, and vice versa? The Russian system is called UPAZ and its manufacturer Zvezda states The nozzle assemblies are adapted to the refueling pods of foreign aircraft http://777.zvezda-npp.ru/engl/zaprav.html Basically this means a bog-standard Russian Mig/Sukhoi cannot plug into a Western ...

The drogue system was standardized in the 50s and reverse engineered by the USSR in that time so nearly all aircraft that use it are compatible with each other.

Primarily because tankers and transports are being operated in non-combat environments or safely benhind the front lines of a battlefield so ejection seats are not absolutely necessary for crew survival. The redundant capabilities of large multi-engines aircraft are such that there are minimal risks of ending up in situation where escapes systems are ...

So first - let's talk about what has ejection seats: Fighter Aircraft. When are ejection seats used? Fighter jets have a glass/polymer dome above them for visibility. The area directly above their head is all one piece, and can thus be "ejected", providing space for a clean exit. There's not a ton of room, which is why pilots are limited to a certain ...

Firstly, any bail out above 20,000 feet has a low chance of survival without supplemental oxygen and tankers usually fly above that height. Also, bailing out of a plane going 450 MPH is an extremely dangerous activity with a high risk of death. The bigger issue is that providing complex, oxygen bearing systems for the full crew would be expensive. Tankers ...

It basically means they will take on more fuel than necessary because the cost of doing so is cheaper than getting the fuel at the destination airport.

N707MQ actually has a special type of experimental certificate, according to its registration it is a "Market Survey" aircraft as you note. The FAA defines this as Market surveys: to conduct market surveys, sales demonstrations, and customer crew training for U.S. manufacturers of aircraft or engines. This does not really provide us any special way ...

It is mentioned in other answers, but I want to point it out explicitely: it's the tanker's role, and to a lesser degree its origin. Big tankers, such as the KC-135, let's call them fleet tankers, are a flying gas station well away from the front line serving all aircraft in the theater of operations, e.g. in- and outbound fighters, the AWACS if present, ...

sorry chaps but a lot of rubbish. In RAF every crew member or passenger has a seat those that have to move around aircraft generally have a chest parachute which clips on to the harness which is always worn.Victor tankers have a max complement of 6. 2 (pilots) have ejection seats but other four have to open the door and jump. Same goes for the Vulcan bomber. ...
