LP / HP endorsements were withdrawn a few years ago during an ops manual re-issue (rev 7?)
The requirements regarding flying types a pilot hasn’t previously flown is addressed by a RAAP. The use of the term “type” in the RAAP is different to the aviation industry standard interpretation, which makes the RAAP difficult to follow. (ie industry defines a type by model / variant, whereas RAAus define type by design features. eg: Industry types: Cessna 172, Piper J3, Beech 58, whereas RAAus use features such as high/medium/slow speed, glass cockpit, wing characteristics, fuel system etc)
