A) True – the rocket should be able to be flown again
B) False – if your rocket is damaged, just buy a new one so the kit manufacturers can stay in business
C12) After two flight racks at your club’s launch, the winds are now causing the rockets to arc over the spectator area before recovery system deployment. You should:
A) Continue launching, the RSO check ensured that any rocket will recover safely
B) Suspend launching and adjust launch pad angles to prevent future flights from arcing over the spectator area
C) Have the LCO announce every flight as “heads-up” until the wind changes again
C13) Your high power flying field is on a local hay farm. There is a hay barn located within 1,000 feet of your launch pad area that is normally unoccupied. One launch weekend the barn is busy with workers and equipment baling and storing hay. You should:
A) Launch anyway, the workers have indicated that they like watching the launches
B) Demand that the farmer move the haying operations farther away
C) Suspend launch operations or move the launch pad area at least 1,500 feet away from the barn

A) 100 feet, 50 feet
B) 200 feet, 75 feet
C) 200 feet, 50 feet
C17) The flight from question C16 was a spectacular success, and now you want to fly the rocket on three Aerotech G75M “sparky” motors. What is the required minimum diameter of cleared area around the launch pad?
A) 50 feet
B) 75 feet
C) 100 feet
C18) It is permissible to launch a high power rocket :
A) Into clouds
B) Near airplanes
C) Neither “A” or “B”
C19) You really want to launch your high power rocket, but the club’s only battery for the electrical launch system is dead. One of the spectators has some green fuse from his last pyrotechnics show.

A) True
B) False
