Aviation Math Formulas
I remember seeing a site that had a list of various aviation math forumulas but am not able to locate it. Anyone have a link or know of a site like this that you wouldn't mind posting a link for?
Also, anyone know what the formula to compute the following problem is? I can compute it on a E6B but don't remember a formula.
If I have to maintain a climb gradient of 4.5% on takeoff and my ground speed is 119 kts during the climb, what would this compute to in feet per minute?
Things have gotten so automated for me that I am forgetting this stuff and need to get a review.
Thanks in advance to all who reply.

I got 943 fpm using a calculator and basic trig. I solved for x which is climb rate, using tan (4.5 deg)= x /119 kts, then convert to fpm using the result times 6040 ft/ 60 min.
There is a pretty good website for aviation math here. It's hard to do math problems flying, and probably not advised, but this will help.

Whatever the VSI says it is. I have never seen any question like this. I have only seen on departures where it says that you need to be able to climb X-number of feet per nm, and there is a chart that tells you what the minimum climb rate you need in order to achieve that. This just doesn't sound like a real world question, just one of those to see if you know those formulas that don't mean anything once you are flying the aircraft. Kind of like the formula to figure out many miles per minute you are flying at a certain mach speed.

This site has lots of formulas

If I can find the link, I'll post it later.
