Incorrect calculation VLS On take off A320

I used a program to calculate speed v2 and in the end I VLS 140, a V2 130. (There is a calculation equation VLS: V2/1.05≥VLS -> V2>VLS.) All data entered correctly: weight 60,000 kg, aircraft A320. So, your value VLS too high.

I’ll add two facts so that there is no doubt that you have a mistake. I asked to calculate the real pilot V2 if weght 60000. He said about 135 kt

And it is worth noting the fact that, VLS just depends on the weight. When calculating v2 - calculator takes into account the inequality: V2>VLS. Therefore, with weight 60000 V2 definitely less than 140.

flaps 1+F?

Flaps 2. No problem, I'll ask him about it)

He has information about VLS with flaps 3 and full (60 000 kg weight). But he asks for a certain amount of money $ for this information (because: “Why should developers make money on the information that was given to them for free”). If you want, you can write to him personally

Sorry, I'll ask someone else then

Ahh, well, I can send you information about VLS personally to your email for free. Send me your address)

Yes, these are the words of my friend:)

Well, in the end he agreed to share information about VLS on Airbus for free. There is information from an article in his airline's document where landing speed is calculated

If relevant:

Takeoff: 135 (1+F), 129 (2)

Landing: 135 (3), 130 (full)
