V-Speeds & Balanced Field Length
V1, VR, V2, VEF — what each take-off speed actually means and why the balanced field length is the runway distance an airliner is gated by.
CG Position & Its Effects
How a forward vs aft centre of gravity changes stall speed, stability, trim drag, and cruise economy — with a slider that shows the trade-offs.
Pressure & Density Altitude — what the engine actually feels
Field elevation isn't what your engine and wing experience. The QNH offset gives you pressure altitude; the temperature offset on top of that gives density altitude — the input to every take-off and climb performance chart.
