Umrechnung Knoten in nm/Minute:

nm/min = kts / 60

ETA - Estimated Time of Arrival

Flugdauer = (Routenlänge in nm / ground speed in kts) + 30 min (für taxi, climb, descend)

z.B. E.g. you have 1000 miles to fly, your 737 does 450 kts gs, you get 2,222 hours to fly. Ad 30 min and you get ~2,7 hours time from gate to gate...
