Why is air speed measured in knots?
HighSkyFlying points out that In aviation, air routes are defined in terms of waypoints (latitude, longitude), and their distance is expressed in terms of nautical miles. Therefore, the use of knots provides a quick estimation of time and speed requirements for pilots.
Is 25 knots a strong wind?
For example, when the average wind speed is 25 knots, it is normal to experience gusts of 35 knots and lulls of lighter winds….Wind warnings and gusts.

|---|---|---|
| 26 – 33 | 36 – 45 | Strong wind warning issued |
Do planes fly in knots?
A typical commercial passenger jet flies at a speed of about 400 – 500 knots which is around 460 – 575 mph when cruising at about 36,000ft. This is about Mach 0.75 – 0.85 or in other words, about 75-85% of the speed of sound. Generally speaking, the higher the aircraft flies, the faster it can travel.
