I see CHC have modified their line training when it comes to how to land on helidecks...
As a reminder:
Touchdown/Positioning Marking Circle. Described as the Aiming Circle in earlier editions of CAP 437, the TD/PM Circle is the aiming point for a normal touchdown (landing) so located that when the pilot’s seat is over the marking, the whole of the undercarriage will be within the landing area and all parts of the helicopter will be clear of any
obstacles by a safe margin.
Note: It should be noted that only correct positioning over the TD/PM
Circle will ensure proper clearance with respect to physical
obstacles and provision of ground effect and provision of
adequate passenger access/egress
