EI521 in Bournemouth?

nag

Just saw an EI flight departing Bournemouth which I thought was odd as they don't fly here. So I looked it up and according to RadarVirtuel, the flight is EI521 from CDG to DUB. The DAA website says the flight is delayed by two hours.

My guess is that they had to make the stop to refuel. It took them a little under an hour from the time they landed to the time they departed again.

If you're of that persuasion, you can replay Casper (London) @ 11.00 and again @ 12.00 to see for yourself.

Flight Number : EIN521
Company : Aer Lingus
ICAO Hex Code : 4CA0FE
Reg Code : EI-CPG
Model : Airbus - A321-211

I thought they would have been able to tanker enough fuel to prevent doing this kind of thing. Obviously not (providing that is the reason they stopped of course).

There's no way that was a fuel stop, there must have been some other problem.

Could be fuel related. Supply problems at CDG at the moment

I would also guess it was non fuel related.

Was watching Euronews this morning and it mentionned the chaos in France right now with the refineries being out of production due to strikes.

Of course there could be technical or medical reasons why they would stopoff as well...

Any flight leaving Ireland for Paris would be able to carry enough fuel for both legs. In fact that would be the logical thing to do.

I agree that it should nearly be possible for an airbus to carry return fuel for Paris to Dublin...there are a few reasons why it may not have been possible.


Using a 737 for ease of calculations because that is what I'm most familiar with.

Empty roughly 42.56 tons + full load (189 pax x 90kgs) = close to 60 tons, return fuel 10 tons. So 70 tons taking off.

Burn would be roughly 3 tons...Therefore arriving in Paris with 67 tons.

BUT

Max landing weight is 65.3 tons

Therefore not possible and could easily be the same for an airbus, needing to pick up fuel somewhere else on the way back.

I'm no aviation expert but I thought that the Airlines would only carry enough fuel for the journey and then topup at the destination so as to save fuel by not having to haul the weight of the extra fuel in a full tank around, or is this only something penny pinching Ryanair does?

Slightly OT question, i was watching the 'last flight of concorde' documentary on discovery last night and it said that the day it crashed in paris, the pilot had expected to use 2 tonnes of fuel taxiing to the runway, but due to favourable ATC they only used c. 1 tonne, meaning it was slightly overweight on takeoff.

Now i know it was thirsty, but could it really use almost as much juice taxiing to runway in CDG as a modern 737/321 would flying there from dublin. Jesus.

Sorry if its OT.

OT. But, you have certainly proven your very first statement.

It is quite the opposite in Ryanair, they "tanker" fuel in a lot of cases as it is more economical to, as you call it, haul the fuel around.

Two tonnes would be the 'notional figure' for weight control purposes and yes it would be realistic for CDG average taxi times.

Take off weight as well is not an exact science as average weights are used for passengers so a 1 tonne over weight t/o could be up to 3 or four tonnes out so wouldn't be a critical factor under the described circumstances.

747 taxi allowance can vary from .5 tonne to 1 tonne.

I found out today that the stopover was for a medical emergency. I believe they wanted to land in the London area but were not allowed in and so opted for Bournemouth instead.

At Amsterdam Schipol there is a very long taxi (with Aer Lingus anyway) I wonder how much juice would an A380 or 747 swallow on a taxi there?

It would be a notional figure, not an actual, as traffic etc would influence the taxi time.

There would be an agreed operational taxi burn.Could be more ,could be less.

I've heard somewhere that an ATR-42 going from Dublin to Galway uses less fuel than a 747 uses in typical taxiing

FlutterinBantam

You probably heard right.

Davidth88

This is getting O/T now , but following the discussion rather than the OP

Didn't Virgin look into ways of towing aircraft to their take off points ( they tried to sell it as a ' green ' measure ) but I have never seen it done .

CDG taxi times are always huge , I remember clearly one time where I phoned my wife that I was going to be ' on-time ' because the aircarft left the stand roughly on time ..... then we taxied and sat waiting to cross runways etc and I ended up 1hr late !

I'm sure I read that on a certain Irish airlines website. I loved them.
