Is the purpose of the optional plugged forward closure, so that no ejection charge is used and you use a altimeter for ejection charge purposes? Are the plugged forward closure and the "standard" forward closure that has the rdk delay charges interchangable.....can you use one or another as you see fit? ie choose to use either engine ejection charge with the standard forward closure or use altimeter based ejection charge with optional plugged forward closure.. sorry to be so dense and such a lamerz per HPR... I'm trying to learn.... TIA
