Ladies, the skydiving company can have a 'Cloud Manual' approved by the APF Aus Parachuting Fed... aslong as the aircraft can climb in VMC (or IMC if IFR), it can drop a load but meat bombs CANNOT open in cloud... hence I think 4,000' from memory can be the lowest cloud base. However, I agree, most are loose operators... and YES I am stereotyping. 6 months, northern wet seasons... I survived!! The most unregulated, bull!!!! I was ever involved in, but it got me my next job so I shouldn't complain. Be safe
