Hello Everybody!

I hope you're all doing well. Here is another super resourceful Quick Reference document from my Grandfather Tom Cassutt's aircraft design archives that he consistently used and referred back to during his lifetime as a pilot, aircraft designer, and builder. I always remembered Tom having these small notebooks that fit in his shirt pocket and he'd always be writing in them and have them with him. I never knew nor asked what they were however I always knew they were extremely important, so now when I go through his archives and see these notebooks of compiled formulas, I realize that's those little notebooks he always had with him.

This specific section of Cassutt's Compilation of Useful Formulas is specific to Plane & Spherical Trigonometry as well as Goniometry. I attached a PDF below. I hope this will be helpful for your own archives and will be something you'll come also use as a resourceful quick reference document.

Anyways, more to come.
Happy Designing!
