4 approaches is relatively rare, but I can pretty much guarantee once you decide to reduce the MDA, it means you ain’t got any more fuel to go anywhere else (unless possibly you had an uncontrollable fire onboard which wasn’t the case obviously) , the interesting thing will be how the crew got themselves into this situation, not the lowering of mda decision……I guess we will find out in 3 years once the ATSB have released the final 😂
