Ask three pilots at three bases whether tonight's weather is a GO, and you may get three different answers for the same conditions. Sometimes that reflects real local knowledge. Often it reflects habit, experience or how the question was asked. Either way, a weather call that means different things at different bases is hard to manage and harder to defend afterwards.
What the overall call is for
The overall weather call isn't a launch decision. Each flight request still gets its own go/no-go decision. The shift call sets expectations for the whole crew at the start of the shift: what kind of night it's likely to be, what to watch and what would change the picture.
- GO: conditions comfortably within the program's limits for the shift, with no significant hazards in the area.
- CAUTION: within limits, but with something worth watching. That might be a deteriorating trend, an AIRMET or SIGMET nearby, or marginal conditions at likely destinations.
- NO-GO: conditions at or below limits, or hazards that rule out the expected operations, for now.
Write the criteria down
Consistency starts with shared definitions. Tie each call to your program's own minimums, by day and night, local and cross-country, and include what counts as a significant hazard. The definitions belong in your operations manual and your training, not in each pilot's head.
Use the same data everywhere
Calls drift when pilots look at different sources. Give every base the same view: METARs and TAFs for home and nearby airports with flight categories, plus AIRMETs, SIGMETs and Center Weather Advisories for the area, all from official sources. See Reading METARs, TAFs and flight categories.
Look at the pattern, not just the call
Over a month, the mix of GO, CAUTION and NO-GO calls by base tells you a lot. A base that never calls CAUTION when its neighbors do may be under-calling. A base with frequent NO-GO calls in fair weather may have a training or equipment issue worth a conversation. Reviewing exceptions, the CAUTION and NO-GO calls, is a quick way to spot both.
BRIEFED records the overall call on every brief, shows each base's mix of calls over time, and lists every CAUTION and NO-GO call in one place for review.
