jesus that is light for that height isnt it!? i know the lightest you can possibly be is 60kg it said (in the 'Application Form Information and Guidance Booklet') but not sure what height that would be for..
yeah thats the min but in the medical they do your BMI (body mass index) weight divided by height, so for someone whos say 150cm tall and someone whos 190cm tall for instance they both weigh 62kg the BMI will be completely different and i believe you can fail on that if it was too high/too low (if not why check it)
They did my BMI, passed everything did everything for her to then say at the end, you have failed because you have got a few spots on my back and face i could of stabbed her why not tell me at the begining, better no have to do it all again (touch wood).
When you have your medical your height & weight are measured, the Medical Officer then looks on the BMI chart to confirm you fall into the "Green Zone", there's no "calculation of BMI" as such, as the chart simply measures height on one axis against weight on the other, where your two figures meet meet will fall into a red, yellow & green zone. BMI figures are of little consequence as long as you are "in the green".
