CAM_01 // RE-ENTRY SEQUENCE
NOMINAL
MISSION FAILED
Impact velocity too high. Parachute deployed too late.
Technical Debrief:
Terminal velocity exceeded 15 m/s at surface contact.
Fnet = Fg − Fd remained positive through descent.
Required: Total Area ≥ 95 m² for safe splashdown.

SPLASHDOWN
What's happening? As the capsule falls, air pushes back against it — that's drag.
The bigger the parachute, the more air it catches, and the more it slows down.
Your goal: keep the landing speed under 10 m/s (about the speed of a fast run).

STANDBY
DRIVER CRITICAL
Impact forces exceeded FIA survival cell limits. Red flag — circuit medical car deployed.
Technical Debrief:
Peak deceleration exceeded 40G — above FIA survival threshold.
Nose cone + survival cell energy absorption insufficient.
Crumple zone length too short for approach velocity.
F1 Impact Dynamics
F = k·x (elastic→plastic) | RK4 Crumple Zone Physics
What's happening? The F1 car strikes a tyre wall. The nose cone absorbs the initial energy — a soft crumple zone means a longer stop time, lower G-forces on the driver. A rigid structure causes an instant stop: potentially fatal. Keep peak G below 40G — the driver survival threshold.
