Choose which fitness and external-pressure items appear in your pre-flight check above the route and discovery inputs.
Everything below lives in this browser and gates every proposed flight. It persists between sessions and adjusts as your flying evolves.
Never a NO-GO. When density altitude sits this far above aerodrome elevation you get an amber row telling you to check takeoff and climb performance.
Your personal minimums can be higher than the published takeoff/approach minimums (e.g. require 2 SM even where a ½ SM takeoff is legal).
A flat personal floor - set it at or above the published approach minimums (DA/MDA) you'll actually fly.
Cloud that is low or deep: ceiling under 1,000 ft, visibility under 3 SM, or a deck at least 5,000 ft thick. For pilots who'd rather not be in sustained IMC. IFR flights only.
Whether a night flight stacks a threat on the decision card.
Unchecking a hazard removes it from the auto NO-GO list. Leave checked unless you know why.
