Yes, I noticed that as well, but assumed that since Sleepybhudda seemed to be only showing typical extracts from the OPS requirements, the same sort of wording probably occurs for OPS 1.665 (b), related to piston engined aircraft. If my assumption is wrong, and these TAWS, WX radar and Emergency lighting requirements are NOT required, then so much the better for procurement of new aircraft at reasonable cost.
But having said that, these items all seem sensible additions, irrespective of whether the aircraft is turbine OR piston powered!
