Having just sat the RSO course - a few thoughts if I was RSOing it:Okay I got a safety question.
I have never been an RSO but seems like with a three engine cluster simmed stable with three motors possibilities as follows:
3 engines light and flies safe as simmed
0 engines light and never leaves the pad but nobody endangered
How about if only 2 engines light or only one lights?
Is this a far pad heads up flight?
The NAR Model Rocket Safety Code states 30 feet for engines larger than D, so a cluster of 3 C6 motors would warrant 30'. I launch low power clusters quite often, and use a 40' cord, which gives me a comfortable 30'. At our large club launches, which can have many spectators, we put the LPR pads at 50', giving us additional safety margin.So, I believe C and below the distance is 15 feet; D makes it 30 feet. Folks correct me if my distances are off.
