SUMMARY

The discussion centers on calculating the correct heading angle for a plane traveling from point A to point B, located 400 km directly south, while facing a wind of 62 km/hr from east to west. The initial calculation suggested an angle of 16.4 degrees, but participants clarified that this angle must be specified in relation to the aviation convention of heading angles, which increase clockwise from zero (due North). The two scenarios presented—one where the plane's nose is pointed south and another where it is adjusted to counteract the wind—yield different heading angles, confirming that the initial assumption of identical angles was incorrect.

PREREQUISITES
  • Understanding of vector resolution in aviation
  • Familiarity with trigonometric functions: sine and tangent
  • Knowledge of heading angles in aviation (0° to 360°)
  • Basic principles of wind effect on flight paths
NEXT STEPS
  • Study vector resolution techniques in aviation navigation
  • Learn how to apply trigonometric functions to calculate flight headings
  • Research the impact of crosswinds on flight paths and navigation
  • Explore aviation conventions for measuring and reporting heading angles
USEFUL FOR

Aerospace engineers, pilots, aviation students, and anyone interested in understanding the effects of wind on aircraft navigation and flight planning.

Homework Statement
This was a two step question on my homework. I got the same answer for both so I think I got it wrong
Relevant Equations
Sin(@) = o/h Tan(@) = o/a
So the question was if a plane is going from point A (origin) to point B 400 km directly south of point A at 220km/hr north and there is a wind going 62 km/hr east to west, what angle should the plane orient to go straight from point A to point B? I got something lik 16.4 degrees. The second part was if the plane flies straight north to south, what angle will the plane be heading? Wouldn't the answer be the same for both?

16.4 degrees measured with respect to what? That is insufficient to specify direction. Same for the second part.

On edit:
Better yet, give the headings using the aviation convention of heading angle increasing clockwise from zero (due North) to 360° as shown in the picture below.

Sorta crappily stated question.

The two aren't the same : the first part implies the nose is not pointed due south (but it still flies due south), the second it is pointed due south (but will miss point B).

Welcome!
Could you post the full text as shown in the original question?
How could the airplane be “going from point A (origin) to point B 400 km directly south of point A at 220km/hr north”?

Its heading was recorded just as it was about to pass over the North Pole? :oldbiggrin:

...or...

The "62"km/hr wind is missing a zero. :woot:
