Question: What's the difference between Strict and Flexible weather safety parameters?
Strict Weather Safety Parameters — non-negotiable thresholds the routing algorithm will never violate when generating a route.
If any part of a potential route breaches a strict limit, that route is rejected.
For optimised routes, if no viable plan exists without violating a strict limit, the optimisation fails outright, giving you immediate feedback on unnavigable conditions.
For shortest and custom routes, a route is still generated even if it involves unsafe weather, accompanied by clear warnings.
Flexible Weather Safety Parameters — preferred thresholds the algorithm aims to avoid, but can breach under specific circumstances. When deciding whether to breach a flexible limit, the algorithm weighs:
Necessity: is violating the limit essential to reach the destination?
Cost of alternatives: how much extra distance, time, and fuel would avoiding it cost?
Degree of violation: how significantly would the limit be breached?
Duration of violation: for how long would it be breached?
If a route breaches a flexible limit, a warning is triggered and shown on the results cards.
