I'm a bit confused...
Operations on a runway that is not less than 18 metres wide must be conducted in accordance with the Australian CAA Approved Airplane Flight Manual Supplement #20 for the SAAB SF340A and Supplement #16 for the SAAB 340B.
I thought the whole idea of the "Australian CAA Approved Airplane Flight Manual Supplement" was that the operations to narrow runways was now part of the accepted certification of the 'airplane' and thus a permanent exemption from CAR 235A - am I missing something?
