A319 need some numbers

Featured Replies

Hi friends.So as most people did during last days i grabbed my stock of that awesome A319 and now what i'm looking for is:1) V1 - VR (medium values)2) climb/descent rate3) flaps settings for takeoff/touchdownI know i could find what i need spotting around but it's so hot here......just lazy :-hahThanksLuigi ;-)

Hi,Well, its all really dependent on wieght really, but I can give you some "ballpark" figures, I do not say these figures are "real-life", but they work for me1) VR - 129 V2 - 1472) This can vary wildly, depending on a lot of variables, but I hold V2 + 20 until 1500 AGL, about 18 DEG pitch, then at 1500AGL drop the nose to 8 DEG pitch, accelerate to 250KIAS below FL100 and hold a pitch to give me 250KIAS then above FL100 drop nose to accelerate to 280KIAS, and hold this up till cruise ALT.Descent is a little more difficult, as the FMC calcs all the descent rates for me ;)3) Flaps, take-off, depending on runway length, 1 or 3Landing, either 3 or full, Vref around 130Hope that helpsCheersDan.

Nice little tool.BTW if you are using the PSS panel, the FMC will give you all the speed data you need ;)CheersDan.

Thank you all for clarifying, and for the useful linkcheersLuigi ;-)

Wolfgang,Thanks for the info. I can tell by the "read me" that my 1st mistake was trying to pull extra fuel in a trailer during T/O.RegardsJackD

In real world, I have also experienced that pilots frequently use fair amounts of airbrakes ("spoilers") on descent, especially when they are positioned into an approach chain. So, kick them in when your speed increases while going "down" - that's what they're there for!Torsten

Dan,First let me state, that I have the PSS Pro and also the PSS A330/340 series and that I am a big fan of these products.However the way the PSS MCDU calculates take off speeds is not very accurate. It does it in a too conservative way and takes only the aircraft weight into account, but not the runway length (very important for V1), not the barometric pressure, not the outside air temperature, no runway conditions etc. Roland Wukovits, the A340 pilot, who designed the freeware "Take Off Performance Calculator" stated in a review of the PSS A330/340, which he wrote for the austrian/german flightsim magazine "FlightXpress", that this inexact take off speed calculation of the PSS MCDUs made him to design his little utility.He states thet the real world's Airbaus take off speeds are much lower than the PSS ones.I remember a few days ago my PSS A332 MCDU calculated the following speedsV1=139, VR=145, V2=153whereas Roland's utility gave meV1=115, VR=129, V2=135for exactly the same situation. This can make a huge difference, especially when taking off from a short runway (overshooting).Wolfgang

Hi,Yeah, since I have been using the little calc utility, I to have noticed that the PSS FMC ones are totally different too.Its a great,great utility, and I implore anyone who uses the PSS panels to get this great little util.CheersDan.

I agree, that is indeed an awesome tool! The only unfortunate detail about it is that it doesn't take runway elevation into account... Best,/Bj
