During a trip to Alaska, where aviation is often the only way to travel and pressures to make flights are likely greater than in the lower 48, some operators use a numerical score to determine the relative risk of a flight and, depending on the risk "score," the go, no-go decision might have to be made by people at a "higher pay grade" than the pilot. Points are assessed for runway conditions (length, width, surface condition), the pilot's experience (hours flown recently, approaches performed, etc.) and weather conditions. As an example, a flight to an airport with a runway that's 2,000 feet long might score a 3, while one to a runway 1,000 feet long would rate a 4. A flight at night might add 3 points while a day flight would add only a 1. If the ceiling at the destination is forecast to be better than 3,000 and a mile, it would get a 2, but if the weather included a ceiling of 1,000 feet and visibility of half a mile, it would get a 4. Once the scores for all the conditions are added up, the value is compared to a risk assessment scale and the relative risk of the particular flight is determined. It doesn't mean the flight won't be undertaken, just that the pilot is made aware of what the risks are.
