Excellent explanation. One question, though. V1 is a speed. But ASDA is a distance. How can a pilot know that he has sufficient ASDA in case of a rejected takeoff? Your videos are super helpful!
Hey so i know aircraft with a higher weight require a higher v1 speed. However a limited shorter runway means lower v1, So would a heavy aircraft have a lower or higher v1 on a short runway? Thankyou.
Firstly, based on the Take-off weight, we would find the value of V2. This will tell how much minimum runway distance we need for the take-off. And if our available runway isn't enough, we'd have to reduce the aircraft weight or increase the thrust of the engines if possible.
@@Dylan-djcali420 No. TODA means Take Off Distance Available. It is what it is. It's not determined. What's determined is TOD which is Take Off Distance. Based on TOW (Take Off Weight), V2 will be determined first. Then, we determine V1 based on TODA. Then, if we see some extra runway available based on the selected V2 and V1 values, we then think of reducing the initial thrust or increasing the TOW.

If you have any question regarding the V1, leave a comment below and I help you out! Happy landings.

Thanks for watching!! We make takeoff performance calculations before each departure
because pilots know the lenght of the runway they use @peteallennh

@muralidharanv9634 so your saying that the v2 value will be used to determine the toda?
