Each pack contains igniters, igniter plugs, and recovery wadding. Letter indicates engine's maximum total impulse (equal to the engine's thrust in Newtons times the length of engine burn in seconds): A=2.5 N-sec, B=5 N-sec, C=10 N-sec. First number indicates engine's average thrust in Newtons. Second number is the delay time in seconds between end of thrust and start of ejection charge. For example, an A6-4 engine has the same thrust and delay time as a B6-4 engine but burns only half as long.
