Weather
Calculators
Enter field elevation, temperature, and altimeter setting to get pressure altitude and density altitude instantly.
Enter course, true airspeed, and wind to get the wind correction angle, heading, and groundspeed, then time en route and fuel for the leg.
Enter the runway and the wind to get the headwind and crosswind components, the way you would for a checkride.
A working scientific calculator with the TI-30XA function set: trig, logs, powers, roots, and memory, for rehearsing the test-day keystrokes.
Load a generic trainer, drag the weights and fuel, and watch the center of gravity move on the envelope.
