What is the required indicated airspeed to reach point B on schedule, given a distance of 70 NM and a forecast wind of 310/15 knots?

To determine the required indicated airspeed to reach point B on schedule, it's essential to consider both the distance to be traveled and the impact of the wind on that distance. The distance is given as 70 nautical miles, and the forecast wind is from 310 degrees at 15 knots.

First, understand that the wind will affect the ground speed, which is the speed over the ground rather than the speed through the air. To maintain a schedule, you need to consider how the wind will either assist you or slow you down. With a headwind, you would need to fly faster to maintain your intended ground speed.

Assuming a certain indicated airspeed (the speed displayed on the aircraft's airspeed indicator), you need to adjust for the wind to ensure that your ground speed over the distance achieves your timing requirements.

To find the appropriate airspeed:

• Calculate the effect of the forecast wind on ground speed.

• If the wind is coming from 310 degrees at 15 knots, it can be considered a slight headwind if you are flying in a direction toward point B.

Based on standard calculations for flight planning, one would typically estimate the required airspeed by factoring the wind correction. In this situation, calculations show that an indicated
