SUMMARY

The discussion focuses on calculating the Sun-O'-Plane angle while accounting for rolling motion in an aircraft. The initial setup involves a signal projected vertically down along the AF axis, with a reference angle known as Sun-O-Plane. As the airplane rolls, the axis shifts from AF to A'F', altering the position of point O to O'. The participants explore geometric relationships, specifically whether the scenario forms an isosceles or right triangle, to derive a correction formula for the new Sun-O'-Plane angle.

PREREQUISITES
  • Understanding of basic trigonometry and geometric principles
  • Familiarity with aircraft motion dynamics and rolling motion
  • Knowledge of angular measurements and reference angles
  • Ability to visualize and interpret geometric diagrams
NEXT STEPS
  • Research the derivation of correction formulas for angular measurements in aviation
  • Study the effects of rolling motion on aircraft navigation and signal projection
  • Explore geometric properties of isosceles and right triangles in practical applications
  • Investigate the use of altitude data in calculating angles in aviation contexts
USEFUL FOR

Aerospace engineers, aviation navigators, and students studying aircraft dynamics who are interested in the mathematical modeling of flight angles and corrections due to rolling motion.

so imagine you have an airplane traveling at an axis projecting a signal vertically down along AF axis and you have some point O on AF axis and a refference angle Sun-O-Plane . the plane gets affected by some rolling motion at a certain known angle... now the axis shifts to A'F' and O become O' I drew a little picture to show my idea. I'm trying to come up wit a correction formula to find out what the new Sun-O'-Plane angle would be .The sun could be at any position. and the information known would be the S-o-P angle along with the planes altitude.

any feed backs guys would be great =)

I'm not sure exactly what you mean.
is the distance PO and PO' the same? Or are we to assume O and O' are on the ground (meaning the height doesn't vary)?
If the first case is correct then your shaded region should be an isosceles triangle.
If the second case is correct then you would have a right triangle.
and in both cases one leg of the triangle is completely vertical.
So, which case is it?

Or am I way off?
 
PO is different from PO' and O and O' lay on ground level which truly makes the shaded triangle right angled. also the height does not varry !
The signal is projected vertically down at first than at an angle when roll motion takes place.

thank you...
