So 567 / 60 = 9.45 MP min.
5699 / 7.45 * 60 = 45,879
yeah, no wonder things are going wrong
speed = 567 mp/h
distance = 5699 miles
taxi = 10 min
sid = 7 min
alt = 4 min
star = 10-15 min
total min waste = 10 + 7 + 4 + 10 = 31 theoretical minutes
total max waste = 10 + 7 + 4 + 15 = 36 theoretical minutes
567 miles/hour div 60 min/hour = 9.45 miles/minute (theoretical)
5699 miles div 9.45 miles/minute = 603.068783069 minutes div 60 minutes/hour = ~10.05 hours (theoretical)
10.05 hours flight time at perfect conditions + 31 minutes of perfect waste (which will never happen at a busy airport such as schiphol) = 10.5678130512 hours = ~ 10 hours and 35 minutes (theoretical)
