I want to learn about how can the V1 and VR (Rotaterotate) speeds be calculated for take off. And which factors are affecting this calculation?
Basically it may depends on the aircraft weight, runway lenghtlength, engine capacity and flap rates. But what is the other factors and what isare the V1 and VR formulaformulas. Is it possible to explain, e.g. for example a Boeing 737 which is taking off from a 6,791 ft (2,070 m) runway in good weather conditions?
