CONSTRAINT #15 activeWeather
Deicing & Winter Operations
Mission timing is compromised when winter weather requires deicing, and the airport's deicing infrastructure or holdover times do not support the departure window.
Decision Question
Does the airport's deicing capacity and fluid holdover time align with the expected taxi and departure queue?
Trigger Conditions
- • Precipitation freezing on aircraft
- • Temperature below freezing
- • Deicing fluid holdover time expired
Affected Mission Layers
weathergroundtiming
Propagation Paths
- Snow/ice → Deicing required → Single truck bottleneck → Holdover time expires → Return for re-spray
Failure Modes
- • Mission delay
- • Forced cancellation
- • Missed ATC slot
Unknowns (Requires Confirmation)
- • Real-time queue length
- • Weather changes during taxi
Recovery Dependencies
- • Central deicing pad vs gate trucking
- • Type I/IV fluid availability
- • Schedule buffer
