In sport skydiving, static line jumps are generally only used for initial-stage training purposes and this practice is in steep decline and has been removed from training practices in most countries .I haven’t seen someone do a static line jump in over 7yrs – I’ve been jumping over the past decade and have over a 1000 jumps.
My viewpoint is that anyone even asking about doing a static line jump would be a novice or new jumper and shouldn’t add the complexity of adding something extra like jumping out of a helicopter.
I’ve got many balloon and helicopter jumps and also don’t see what fun doing a static line jump would be – akin to pilot queries, you can usually judge someone’s skill/understanding by the queries they ask.
