I had similar probs upon applying through OASC. I weighed 89kgs at 17.5yrs old and i was told that i had to be 82.5 or below to even be considered. Bearing in mind that i was playing professional rugby and am about 6ft tall, it was bloody hard work i can say!!
Being the keen youngster i was, i stopped playing rugby for a month and basically starved myself!!!NOT RECOMMENDED!!!
I got down to the said 82.5kgs and i looked ill. All OASC needed was a chit from my local GP saying that i'd reached the weight and they were happy.
Due to still playing rugby to a reasonable standard, i have constantly struggled with the max nude weights for ejection seats. The tucano was 95kg nude and i was riding the buffet all the way thru linton. God knows what it will be like on the hawk where i can imagine the nude weight is a bit lower!!
If anyone knows the nude weight for the hawk off the top of their heads it would be greatly appreciated!
