Required landing distance available. Does inflight requirement exist?

Commanders Decision

I remember the day that we had 40 kts headwind. Besides the wind there are of course the gusts.

Now there are two issues here:

1. Accurate landing: very difficult
2. Passengers comfort: several idiots tried to land and the result was. Two pax suffered a heart attack and a couple wetted their pants.

I never even tried the approach.

From the post above I can only conclude that to be 100% sure, the only way I will board an aircraft when the wx is marginal is when I am flying myself.

Checkboard:Contingency is there to cater for inaccurate planning. You need it before starting the flight. Factoring is there for inaccurate landing, deviations from planned braking action. As with contingency, you need it BEFORE starting the flare.
