FLEX/TOGA on A319 from EGGD
HI all
I frequently fly from EGGD, both as a pilot of a PA-38 based there (G-BPPF) , and as a PAX with Easyjet
Something i always wandered, is wether the T/O in the EZY A319s are done with FLEX Temp selected, or TOGA ?
The runway is not small ( ~7k ft) but was wandering how much % of N1 is needed to get one of those birds away for the typical 2 1/2 hr flight
Geeky, i know..
Thanks

Not sure about EZY, but I fly out of there on A320s for GB and quite often we need TOGA and FLAP 2/3. Mind you we're going on a 4 hour flight to Tenerife. I'm sure a 319 could get out, on a 2 1/2 hr flight with FLEX. But i may be wrong.

Some of the guys from BRS might have a more accurate answer, but Im based at LPL, and the runway there is not exactly long. EZY SOP is to go with FLEX take off whenever possible and therefore I would suspect that in the vast majority of cases this would be the case.
Even with quite a load, the FLEX temp can be used, albeit sometimes quite a low assumed temp.
The "tough book" gives a range of flex temps, but we generally go with the highest available given all the limiting factors.
Unless you flew on a Monday morning when you may have got on a flight where the crew had set TOGA to satisfy maintenance.
Cheers

In 6 months of operating A319's from EGGD I have never used Toga. Flex is always high 50's to high 60's and the loads have been epic all summer.

The EZY MTOW is either 68, 66 or 64 Tonnes depending on the aircraft Reg. With weight, (airways)charges go up hence most a/c are down as 64 Tonners, this whoever would be insufficient for the longer routes like RAK and ATH.
I believe the absolute MTOW for the A319 is 68T

Bear in mind also, that even if you use TOGA, you well still be well under the rated thrust the engine is capable of.
In BA the same V2500 engines are fitted to A319/320/321 aircraft and it is just a pin change to upgrade the thrust you get with TOGA from 22K? on the A319 to 33K? on the A321. So an A319 at 22K TOGA is still massively derated in absolute terms.

CFM engines at EZY not the dreaded alternative.
But the same principle applies.

There are some airlines in the world that doesnt use derate...
Because that is cheaper for them to not do that and the reason is
the leasingcontract on the engines...
The airline that doesnt do this dont pay the engine maintance just
the fuel and tyre price...

Thanks for your answers everyone.
Do these ballpark values (82-86% N1) also apply when the runway is wet ?
I've read somewhere that the SOP for a Airbus is to use TOGA with a wet runway ? ( i have a feeling its not as clear cut as that..)

Hiya again Portugeezer......
I think you are getting confused or mis-directed by your last post, wet runways do not preclude the use of FLEX take-off settings. Contaminated runways do - and thats a different topic entirely.
Cheers.
