If the true airspeed is 110 knots and groundspeed is 98 knots, what is the wind speed?

To find the wind speed when given true airspeed and groundspeed, you can use the following relationship:

Wind Speed = True Airspeed - Groundspeed

When you substitute the values provided:

True Airspeed = 110 knots

Groundspeed = 98 knots

Now, performing the calculation:

Wind Speed = 110 knots - 98 knots = 12 knots

This indicates that the wind is affecting your groundspeed, which is the speed over the ground. Since 12 knots is the difference between the true airspeed (which is your aircraft's speed through the air) and the groundspeed (which is the speed over the ground), this shows the actual wind speed.

The calculation points to an understanding of how winds can alter the speed of an aircraft relative to the ground. This also emphasizes the importance of accounting for wind when planning flights, as it can greatly affect flight time and fuel consumption.

In this case, the correct answer reflects the accurate understanding of how to perform the calculation involving true airspeed and groundspeed to determine wind speed.
