B412 HELIPAD DIMENSIONS
Hi B412 Drivers,
Can anyone explain why the B412-FMS-62 requires a Helipad dimension of 25.9m x 22.9m for Ground Level Helipad Operations but only 18.7m x 18.7m for Elevated Helipad Operations.
My small brain is confused by the issue; if the Elevated Helipad procedure affords a higher Take-off/Landing Mass (because you can do the Dropdown profile) and the references are arguably less than for a Ground level helipad, why is the site dimension allowed to be smaller?
I have asked the Bell rep for an answer but would be interested if anyone has faced this issue before.
Thanks DB
