Do I weigh to much for a helicopter

Hi all,

Im a wildlife biologist and will be flying in helicopters over the next few months for aerial ungulate surveys.

I weigh 320lbs and am 6’5.

Will I be allowed to fly? We will be using A-stars.

I wouldn’t be offended if I’m turned away, however I just want to have a rough idea of what the standard weight limit would be.

Any and all help would be grateful.
