Bernoulli’s principle. An interesting subject regarding jet engines.
Please ping me to aviation and aerospace articles. Thank you.

How pitot-static air pressure can be mechanically measured. Then show her the pitot tubes and air data probes.
I can’t help, but wanted to give kudos to your teaching your kids, and making math interesting.
I wish my dad had done that.
I’m still ‘number phobic’ despite eventually getting through Calculus, and D.E., etc.
One more. How is fuel capacity measured. How do pico-farads determine the amount of fuel left?
“... measure the tops and bottom of wings and rotos and figure the ratio or difference between the area of the top of the wing versus the bottom and estimated which wings had more lift than others.”
Keep in mind that lift is about 25% Bernoulli Effect and about 75% displacement depending on the wing cross section.
We know what the speed of light is, but what is the speed of thought?

convert all the measurements from imperial to metric or vise versa.
If plane A leaves New York traveling non-stop to Los Angeles at 430 knots, and plane B takes off from NY traveling non-stop to LA two hours later traveling at 460 knots, how long will it take for plane B to catch up with plane A?
How much of a jet engine’s thrust is needed to overcome drag.
I like that. For a little variety, have her sometimes do a Conservation of Energy trace (don't worry, it just sounds tough, it's easy).
First recall that energy is the ability to do work.
Conservation of Energy: Energy cannot be created or destroyed, just transferred.
So here's an energy trace example. A plane taxing down a runway has kinetic energy (energy of motion). That energy has to come from somewhere, and go somewhere.
Where did the plane's kinetic energy come from? It came from gasoline in the plane's fuel tanks. Where did the gasoline's energy come from? From the ancient plants that formed oil. Where did those plants get that energy? From the sun. Where the sun got its energy is a religious question!
Now suppose the plane stops. Where did the plane's kinetic energy go? It has to go somewhere! The plane's energy was converted into heat by friction. The plane's tires get hot, and eventually the whole universe will get just a tiny bit warmer.
You can do such energy traces with a person walking, the energy stored in a hamburger, the energy stored in a brick at the top of a building, etc. I think it's quite fascinating.
If you have any questions about this, feel free to FRmail me. The first hundred questions will be free!
Can’t come up with a specific equation, but the effect of engine torque on controlling the aircraft — the Corsair had a lot of torque to overcome.
With the P-38, the effect of dual props turning in the same or different directions.
If you look around, you should be able to find some things that are at least interesting from a historical education perspective, but could give some math or physics education.
Check out Aerodynamics for Students. Looks like there's a fair amount of material that is suitable for algebraic understanding. I'm sure you'll have her in to DiffEq real soon!
Lots of other math can be demonstrated with a flight computer, which is essentially a circular slide rule. The ASA A6B paper flight computers are CAD $13.95 and the metal version is $32.95 here.

From tire pressure and flattening try to estimate total weight and center of gravity. Estimate fuel tank capacities and cg locations. Work out trimming needs and fuel management.
