Having seen some Cat A flight tests with bended skids by testpilots and since them i believe Cat A is only a paper
to find an alibi for JAA. If we are light enough to fly Cat A elevated heliport, we can fly in the OEI limits mostly. For BK117 OEI limit 140% for 12 sec.
And Cat A seems to run out in some countries because most twins are allways to heavy for Cat A charts on the usual operation weight. The new wizard is therefore "exposure time". For BK117 15sec. Leave the spot as quick as possible and don't stay endless in backward high hover.
Amusing!
