CONSTRAINT #09 activeWeather
Weather Minimums & Alternate Requirements
Mission viability is restricted when destination weather falls below legal minimums, requiring a diversion to an alternate airport.
Decision Question
Does the destination weather forecast preserve a legal window for the intended approach, and is an alternate airport viable?
Trigger Conditions
- • Ceiling/visibility below approach minimums
- • Thunderstorms/Severe weather
- • Crosswinds exceed aircraft limits
Affected Mission Layers
weatherairporttiming
Propagation Paths
- Weather drops → Below minimums → Pilot cannot begin approach → Divert to alternate → Ground transfer broken
Failure Modes
- • Forced diversion
- • Mission delay
- • Ground transfer failure
Unknowns (Requires Confirmation)
- • Real-time weather changes
- • ATC routing delays
Recovery Dependencies
- • Alternate airport planning
- • Ground transfer flexibility
- • Schedule buffer
