Yemie Mark 1 Posted May 24, 2013 Share Posted May 24, 2013 As the title I wanna know how your guys set takeoff flex, cos when i was in Skiathos I use present tempreture as take off flex and I fund that it is hard to take off at that short use 25 flex.

Adrijan 193 Posted May 24, 2013 Share Posted May 24, 2013 I think you should takeoff with TOGA at Skiathos at all times. Also, what was your weight (pax/fuel/cargo)? If you left it at default, there's a great chance you can't take off. Link to comment Share on other sites More sharing options...

KyleD 1027 Posted May 24, 2013 Share Posted May 24, 2013 Agreed on TOGA and flaps 2 there. Same goes for other tight squeezes like Gibraltar. Link to comment Share on other sites More sharing options...

Yemie Mark 1 Posted May 25, 2013 Author Share Posted May 25, 2013 When I took off at Skiathos I used TOGA and flap 2 ...ya.. That is in skiathos how about normal airport that has full runway like 12000+feet how about this case. Link to comment Share on other sites More sharing options...
Fab10 34 Posted May 25, 2013 Share Posted May 25, 2013 Try TPC (takeoff performance calculator; free) to calculate v-speeds and flex temp according to various factors such as runway length, runway conditions, temp, QNH, altitude, weight, anti-ice etc (to replace values given by AXE as its perf table needs revision). There are a couple more tools available for the Airbus here: http://www.vbird-va.nl/airbus/tools.htm Link to comment Share on other sites More sharing options...
Nthabti 18 Posted May 26, 2013 Share Posted May 26, 2013 There are a couple more tools available for the Airbus here:http://www.vbird-va.nl/airbus/tools.htm Hey Fab, Have tried to use the Excel-based Less Paper Cockpit? It is working for the A320 but not for the A321. I have tried to find a solution within the program and online, but without any luck. Would appreciate help here, as it is a great tool.

Fab10 34 Posted May 26, 2013 Share Posted May 26, 2013 Hi, Actually, I just use TPC, but I'll have a look at the spreadsheets. What issues are you experiencing? Fabio Link to comment Share on other sites More sharing options...
--- 170 Posted May 26, 2013 Share Posted May 26, 2013 I think you should takeoff with TOGA at Skiathos at all times. Why? Even at 64t you can take off with a flex temp of 50°C IRL. Link to comment Share on other sites More sharing options...
Emi 5161 Posted May 26, 2013 Share Posted May 26, 2013 Why? Even at 64t you can take off with a flex temp of 50°C IRL. Are you sure about this on a runway with 1800m only? Link to comment Share on other sites More sharing options...
--- 170 Posted May 26, 2013 Share Posted May 26, 2013 RWY lenght is only 1628m. Just tried with the AAX at 64t, conf 3 and a flex of 52°C... works perfectly (V1 120, VR 124, V2 128) Link to comment Share on other sites More sharing options...
Emi 5161 Posted May 26, 2013 Share Posted May 26, 2013 Allright, thank you very much. So you say it's just as it would be in real life in our Airbus? Link to comment Share on other sites More sharing options...

gandy 25 Posted May 26, 2013 Share Posted May 26, 2013 Umm i close my eye's to it as i have not got that far in learning the systems, takeoff flex.. what takeoff flex I will get there but not yet as im ironing out my flight planning as i want to get that perfect before i take the next step Link to comment Share on other sites More sharing options...

Mmmm but would a real pilot get THAT close to the ragged edge of the flight envelope? Link to comment Share on other sites More sharing options...
--- 170 Posted May 27, 2013 Share Posted May 27, 2013 Of course, regularly, because it's not a ragged edge, but a well defined one plus a few 'built in' safety features like e.g. only 50% of the entered headwind but 150% tailwind are used for the calculation.

Aerosoft Aerosoft Team [Inactive Account] 51558 Posted May 27, 2013 Aerosoft Share Posted May 27, 2013 I know it will lift off, but you keep enough runway to stop before Vr? RWY length is 1628m after all. Link to comment Share on other sites More sharing options...
--- 170 Posted May 27, 2013 Share Posted May 27, 2013 At VR it's too late. Once V1 has been passed the first action to abort the take off must have been initiated already as there's really no room for a late reaction if you are really close to the runway limit. (A lot of people still believe that V1 is a decision speed but it's actually an action speed since long ago). The Skiathos example I posted results in a stop margin of exactly 1m! IRL it would be possible to reduce the flex from 52°C to e.g. 45°C to increase the stop margin. But if you are really heavy, it's hot and the stop margin is 1m without any flex, you have to accept that without the possibility to sqeeze out any further stop margin.
