Pub Quiz time..

[sbdorset]

Can any Pruners solve a Pub Quiz argument? What is the average hourly fuel burn of an A320.

Not to the nth degree just an average please.

[Gryphon]

OK, I'll take the risk, but only if everybody agree we're in a Pub after several beers and tomorrow we're not flying.

With a cost index slightly below LRC and landing weight 60 tons, trip fuel 37 kgs per minute flight time.
To be corrected half a Kg per minute per ton, above-below 60 tons landing weight.
This is only trip fuel, of course.

OK, too many beers. Time to go! :O

So a bit over two tonnes,then?

[Superpilot]

In cruise, at a healthy weight go for 1,500kg per engine, so 3t per hour.

And in true pub style comparison, about the same as 200 Ford Cortinas (each one 15kg per hour). Dixie was spot on with his maths!

[sbdorset]

Thanks - the Doom Bar will flow later!:ok:

[qwertyuiop]

A new 320 with Sharklets fitted is only just over 2 tonnes per hour.

[pilotmike]

...about the same as 200 Ford Cortinas (each one 15kg per hour)

Those would be very thirsty Ford Cortinas!

15kg (@0.755kg/L - standard density for road petrol) is almost 20L/hour. You'd need to be going at 100mph returning just 23mpg to burn petrol at that rate!

At a more reasonable 70mph returning 30mpg, you'd be burning under 11L/hour, around 8kg/hour. So the A320 is burning fuel at a similar rate to 375 of those Cortinas being driven equally sensibly.

Today's diesel car returning 70mpg at 60mph burns under 4L/hour, or 3.25kg/hour, so 925 of them could be cruising along at 60mph whilst burning no more fuel than just the one A320 in Superpilot's example.

A pint of Doom for me please - regards to Rock!

2400kg. ..

Can I ask the same question for a 747?

[Flap33]

747-400 : About 10-11 Tonnes per hour decreasing to about 8-9 at the end of the flight .

777-200 : About 7 Tonnes per hour decreasing to 5.5-6 at the end of the flight.

777-300 : About 15-20% greater than 777-200

[Superpilot]

pilotmike,

Well that's how my dad drove them, so there! ;)

[Amadis of Gaul]

Ford Cortina...there's a model I haven't heard mention of in a while..I'm surprised you pommies didn't stick a Reliant Scimitar in there for some extra fun.

[dash6]

So for only another 500-700kg you could get a 757?
So what is the point of the A321?

[Superpilot]

"Only another 700kg" costs about about £600 per hour, multiply that by the number of hours in your average sector length.

1,500kg per hour, per engine is for a fully loaded A320 with full fuel, it comes down to 1,100kg per hour, per engine for an almost empty one as others have pointed out.

What's the point of an A321?

There's more to it than just fuel - think fleet commonality (crew, training, parts)

[Amadis of Gaul]

For about another billion kilos you could get an An-225. What's the point of any airplane?

[DooblerChina]

757 3.2T/hour. 220 pax.

[Superpilot]

What kind of fuel weight and gross weight would that be for?

[Thai Pom]

I'm not coming to your Pub if this is all you talk about !!:)
