CAT.POL.H.325(c) GM1 PROCEDURE FOR CONTINUED OPERATIONS TO HELIDECKS
(a) Factors to be considered when taking off from or landing on a helideck
(1) In order to take account of the considerable number of variables associated with
the helideck environment, each take-off and landing may require a slightly different
profile. Factors such as helicopter mass and centre of gravity, wind velocity,
turbulence, deck size, deck elevation and orientation, obstructions, power margins,
platform gas turbine exhaust plumes etc., will influence both the take-off and
landing. In particular, for the landing, additional considerations such as the need for
a clear go-around flight path, visibility and cloud base, etc. will affect the
commander’s decision on the choice of landing profile. Profiles may be modified,
taking account of the relevant factors noted above and the characteristics of
individual helicopter types.
