Re: Throttle levers on 4+ engined aircraft

I wouldn't have thought 4 throttles would be a problem, their curved indentation shape natually fitting to 4 fingers of a hand, but I've often wondered about 6 engined (An225?) or even 8 engined (B52?) aircraft. Are their throttles easy to manipulate togther?

Qantas hasn't said it though. I mean the A350 - 1000 will be capable of flying from Newcastle to London nonstop ut it doesn't mean it will happen.

Re: Antonov Design Bureau Operations

Apparently there's some speculation on the Facebook threads that the An-225 destroyed in the hanger fire might have been the half assembled 2nd aircraft that was apparently stored there.
I do hope this is true and that first, airworthy example survives.

Re: Curved runway starter extensions

I think Brooklands airfield in the UK had an offset starter extension. In the 1960's, Vickers manufactured the VC-10 there, and since the runway was < 4000 feet, each new VC-10 was required to use the starter extension to depart to the nearby Wisley airfield (which had a longer runway) for final fit...

The idea behind the Kruger Flap/Slat arrangement,was, in the event of a stall, that the inner part of the wing stall before the outboard part of the wing, thereby keeping roll control.

Re: DC-10 tail mounted engine angle

High mounted engines will tend to make the aircraft go nose down, just as low slung engines want to make the nose rise.
I suspect the nose up/tail down angle of the DC-10's rear engine is to offset this tendency.

Re: HS Trident

Very interesting thread, thanks for bringing this up. As a classic-jet enthusiast, I must say that I really miss this type of threads on A.net during the last years. It appears that there is not so much interest for early jetliners anymore. Same, it's why I chose my a.net username way back when (th...

Re: Altimeters, static pressure, and lift

Cavitation is caused by a phase change, the rate of phase change depends upon local flow conditions (pressure, velocities, turbulence) as well as fluid properties (saturation pressure, densities, and surface tension). It is not a result of one factor. Cavitation is used all around us, like fuel inj...

Re: Boeing 727 Leading Edge Device Question

The slat intermediate position usually has the slot between wing and slat sealed, making the slat effectively a 'leading edge droop' in this position. This is a compromise position that develops extra lift, but at much less drag than with the slot open (e.g. slat fully extended) - which is ideal for...

Re: Holes or gaps in the upper surface of trailing edge flap segments?

Drag is a of major importance during cruise, but when the flaps are extended (and these 'holes' appear) it's of much less a concern, indeed it's very useful for better speed control down the approach.

Re: Which airliners have two jackscrew assemblies to control their horizontal stabilizer?

How do these multiple jacks operate then if one hydraulic system goes down - with a jackscrew being irreversible? Unless they're placed in series (one after another) I guess, rather than in parallel (side by side) as you'd expect I can't see how they'd work. On the MD-11 the two nuts are connected ...

You can't tell the angle of attack from just looking at footage or pictures. i would guess with very high resolution cameras these days sometimes you can if you (can) zoom in enough. best regards Thomas I think Starlionblue's point was that angle of attack is also a function of direction of travel ...

Re: What causes the pause on some aircraft between the time the nose is lifted off and the mains break free?

The DC-8 uses a plain flap design with hinges. Airbus and Boeing usually use Fowler and slotted flap designs. I don't think they're quite plain flaps - but similar to the 707 type fowler flap where the actual rearward extention is fairly low compared to modern types which have a large area-increase...
