What is the required indicated airspeed to reach point B on schedule from point A?

To determine the required indicated airspeed to reach point B on schedule from point A, it's crucial to consider factors such as the total distance to be covered and the time allocated for that travel. In a flight planning context, the indicated airspeed must allow the aircraft to cover the distance efficiently while adhering to the scheduled timeframe.

Selecting 137 knots as the answer indicates that this speed effectively balances the flight's operational parameters, including wind conditions, aircraft performance, and fuel efficiency. A speed of 137 knots is likely calculated to accommodate these elements while ensuring timely arrival without exceeding any operational limitations.

Conversely, the other speeds mentioned may not allow for sufficient performance in relation to the required schedule or might lead to complications such as higher fuel consumption or less optimal flight path management. Thus, choosing 137 knots as the required airspeed suggests that it is the most effective option for completing the flight from point A to point B on time.
