What is the main factor in determining the indicated airspeed for a scheduled arrival?

1. Wind conditions

2. Altitude

3. Time and distance

4. Aircraft weight

The correct answer is: Time and distance

The main factor in determining the indicated airspeed for a scheduled arrival is the combination of time and distance. This relationship is crucial for pilots to manage their approach and landing phases effectively. When planning for an arrival, pilots consider the distance remaining to the destination and the time they have allocated for deceleration and landing. Indicated airspeed is vital for ensuring that the aircraft arrives at a specific point in a timely manner, allowing for adjustments in speed as needed based on the distance yet to travel. Accurate management of airspeed directly affects the approach plan, allowing for the appropriate configuration of the aircraft as it descends toward the runway. While wind conditions, altitude, and aircraft weight play significant roles in flight performance and operational control, they are secondary to the need to maintain an approach profile that aligns with the scheduled time of arrival. Hence, the emphasis on time and distance makes it the primary factor in determining indicated airspeed during the arrival phase.
