Coriolis Deflection Estimator implementation

Binding contract

This record describes what an executable surface must bind and validate. It does not claim that a public calculator, package, or production route is deployed.

Computation or source lookup only

Input and validation requirements

The scalar formula can compute a magnitude or signed latitude-dependent scalar, but it cannot uniquely compute a physical deflection direction without an explicit velocity-bearing convention. The instrument must also suppress hemisphere direction labels when velocity is exactly zero and handle extreme finite inputs without overflow.

Required corrections

No binding erratum is attached to this unique-name record. Implementers must still preserve the declared units, domain, and failure behavior.

Inspectable interface fixture

The sample below is evidence for interface and validation tests, not a production implementation.

{
  "inputs": {
    "latitude_deg": 45,
    "velocity_m_per_s": 10,
    "velocity_direction": "northward"
  },
  "expected_outputs": {
    "coriolis_acceleration_m_per_s2": 0.0010312609,
    "deflection_direction": "right of motion (eastward)"
  },
  "working": "2Ω = 2 × 0.000072921159 = 0.000145842318 s^-1. sin(45°) = 0.70710678. a_cor = 0.000145842318 × 10 × 0.70710678 = 0.0010312609 m/s². Latitude is positive, so a northward-moving object is deflected right, toward east."
