indicated that a bonus will be awarded for landing at airports or approved
landing sites:

who lands at a designated airfield receives a score bonus for such a landing.
The landing must take place at a field designated by the CD as eligible
for such a bonus.
Eligible fields shall be designated prior to the start of the competition.
