What does a groundspeed of 98 knots indicate compared to a true airspeed of 110 knots?

What does a groundspeed of 98 knots indicate compared to a true airspeed of 110 knots?

• A. The aircraft is losing speed
• B. The aircraft is being pushed by headwind
• C. The aircraft is encountering tailwind
• D. The aircraft is descending

Answer: (B)

A groundspeed of 98 knots indicates the speed of the aircraft over the ground, while true airspeed (TAS) of 110 knots is the speed of the aircraft relative to the surrounding air. The difference between these two speeds suggests the presence of wind affecting the aircraft. When the true airspeed is greater than the groundspeed, it indicates that the aircraft is facing a headwind. This is because the wind is blowing against the direction of the aircraft's movement, reducing the effective speed over the ground. In this case, since the true airspeed (110 knots) is higher than the groundspeed (98 knots), the aircraft is indeed being pushed by a headwind. Thus, the correct understanding is that the discrepancy between the true airspeed and the groundspeed corresponds to the effect of a headwind slowing the aircraft's progress over the ground relative to its speed through the air.
