Subject: DBF Q&A #3
DBF Q&A #3 29Nov99
Q: Is it required that the aircraft empty the payload for the non scoring
runs?
Could we leave the water in for ballast in windy conditions?
A: No, that is the whole point for having the "unloaded" lap
requirement. The airplane must be designed to handle well, including wind
conditions, at both full and empty weights and cg locations. Since the
"ferry" sortie is non-scoring (see the next question) you also want that
sortie to expend as little electrical energy as possible, and as little
time as possible, so you can compete another "payload" flight after it.
Q: In the FAQ you have the following statement:
"If the plane does not pass the downwind pylon that sortie's payload will
not count, but any prior sorties will still be credited toward the overall
score. "
So say you flew this mission "water-empty-empty-water" and the batteries
died right after the plane reached the second pylon of the second water
lap, forcing the pilot to land. Would both the payloads count towards the
final score, or just the first? In other words, does the plane have to
complete an entire 3 lap sortie for the weight carried in the sortie to
count?
A: In this case you would get the score as the weight carried on both
"payload" or "water" sorties. The ferry sortie has no specific score
value, so the only way to increase your score after completing one
"payload" sortie, is to complete both the "ferry" sortie and then another
"payload" sortie.
For the example above, the score would be the same if you completed
"water-empty-empty-water-empty-empty", but did not have enough battery
power left to complete a third "water" or "payload" sortie.
Remember, you must land and load/unload the payload between each "water" or
"empty" sortie, but not between the two consecutive "empty" laps.
