Final answer:
The precise number of degrees a pilot should change the heading by when a parallel offset is assigned and accepted depends on the specific context and is not detailed in the provided information. However, in situations involving wind, pilots must adjust their heading based on vector equations that account for wind speed and the plane's relative airspeed.
Step-by-step explanation:
If a parallel offset is assigned and accepted, the specific number of degrees a pilot should change the heading by can vary depending on the context of the flight path adjustments. However, based on the provided information, it does not precisely state how many degrees should be changed in case of a parallel offset. Instead, the information discusses a scenario where a pilot must compensate for wind by adjusting the plane's direction to reach the intended destination.
Wind Compensation Strategy
The pilot must point her plane somewhat east of north to compensate for the wind velocity. This involves creating a vector equation containing the velocity of the plane with respect to the ground, the velocity of the plane relative to the air mass, and the velocity of the air with respect to the ground. By knowing the velocity of the plane relative to the air mass and the air's velocity with respect to the ground, the pilot can determine the necessary velocity and direction to head the aircraft to compensate for wind effects.
Qualitative Effects of Wind
Wind coming from the north would alter the flight path of the plane. The impact depends on the relative wind speed and the speed of the plane relative to the air mass. A faster wind speed would require more compensation than a slower wind speed, and if the plane's airspeed is higher, it would be less affected by a given wind speed.
Example of Flight Path Adjustment
In the provided scenario, the pilot’s course is altered by wind coming from the north. To arrive at the final position as planned, the pilot must adjust the plane’s heading. The magnitude and direction of this adjustment are determined by graphing the necessary vectors and solving for the plane's ground velocity and direction.
