FIFO miners are frequent flyers, many of them would clock up more hours than management pilots. Four goes at landing would have been noticed, the crew did the right thing in reporting it rather than being called in for an explanation a few days later after the news got back.
The problem lie’s in trying to run according to an ops manual which is more suited to capital city and regional centre operations rather than remote areas with very limited facilities.
Anyone who’s operated in the GAFA knows that the TAFs are all the same for every airport within hundreds of miles. There is a winter one and a summer one, resources go towards the populated areas.
Mining companies are well resourced and having a qualified MET observer on hand for airports with high capacity flights wouldn’t be difficult. In most of the world, an alternate is mandatory and should be seriously considered for remote area ops, rather than relying on a generic forecast being above the alternate minima.
