WINTER OPERATIONS REFERENCE CARD
01 NOV 2026   •   FLEETWIDE WEATHER REFERENCE
1.  Preflight weather scan
METAR
Operational meaning
SN / +SN
Snow / heavy snow
FZRA / FZDZ
Freezing rain / freezing drizzle
PL / GR / GS
Ice pellets / hail / small hail or snow pellets
BLSN / DRSN
Blowing snow / drifting snow
FG / FZFG
Fog / freezing fog
RVR / runway condition
Use runway-specific observation, braking reports and performance inputs
2.  Holdover reference selection
Use the current FAA 2026–2027 tables, not a fixed value on this card. FAA Table 57 assists in snowfall intensity determination by visibility; Type I tables distinguish predominately aluminum and composite critical surfaces. Type II/III/IV tables depend on particular fluid characteristics.
3.  Restricted conditions
Heavy snow, ice pellets, freezing rain and mixed precipitation require careful review of FAA table limitations. A red or “no HOT” table entry is not authorization to depart after an arbitrary interval. Apply only an authorized pathway or re-treat.
4.  Taxi / takeoff / landing
Check contamination on surfaces, taxiways and runway. Reassess braking and takeoff/landing distances using model-specific performance information. Account for deteriorating conditions, rejected-takeoff exposure, crosswind, alternate availability and diversion.
5.  Reminders
HOT begins with the start of final anti-icing application. Changes in precipitation and temperature matter. Clean-aircraft verification is a separate requirement. Type-specific FCOM/QRH controls engine anti-ice, wing anti-ice, flap positioning and engine run-up.
