| Apr 15, 2017 at 2:51 | comment | added | radarbob | The aircraft wing is only "aware" of the air flowing over it, and air moves relative to the ground - wind. Meaning, the airplane performs - flies - based on airspeed and we know when we'll get to our destination based on groundspeed. | |

| Apr 13, 2017 at 21:38 | comment | added | Talisker | (Assuming no GPS, as was the case for most of aviation history) You need true airspeed to find how fast you're moving relative to the airmass, then you can use wind weather data to approximate how fast you're moving relative to the ground, to find out how far you've traveled and how long your journey will take. | |
| Apr 13, 2017 at 21:34 | comment | added | Simon | @RonBeyer That's going to mean nothing to the OP. | |
| Apr 13, 2017 at 21:31 | comment | added | Ron Beyer | Because ground speed doesn't directly translate to V speeds, and V speeds don't directly translate to ground speed. | |
| Apr 13, 2017 at 21:24 | comment | added | JScarry | And why do we need True Airspeed too? :) | |
| Apr 13, 2017 at 21:23 | comment | added | Simon | Without groundspeed, how would you know how long it will take to get from A to B? | |
