Helicopters are the aircraft
of choice for the majority of aerial
cinematography duties as they offer the most
in versatility. The ability for multidirectional
flight gives the aerial cinematographer control
and finesse over the movement of the camera
much like the director of photography would
do with any ground-based camera dolly.
Choosing a suitable rotorcraft camera ship
is predicated on the demands of the shot
and the camera mounting system to be used.
The ones shown here are the most utilized
with the majority of commercially available
filming systems having been designed and/or
certificated for installation.
Equally important to consider are the many
variables affecting the inflight performance
characteristics of the helicopter, the most
significant being air temperature, pressure & density
altitude, moisture content of the air, gross
weight, external stores (ball mounts in particular
fall under this heading) and wind.
In addition, each helicopter
has its own maximum airspeed limitations
(expressed as
VNE - velocity never to exceed) which will
be further reduced by the installation of
any camera mounting system. There are definite
reasons for these limitations and under no
circumstances should they ever be exceeded.
Number of people on board factors into the
aircraft gross weight which will affect performance,
particularly at altitude or during hover.
Increased weight aside, with certain camera
mounts there quite frankly will not be enough
room left, beyond the pilot and operator,
to accommodate any more passengers other
than maybe the director. Portable Combo 8
units can be used to record video assist
for later playback on the ground.
Discussing all aspects of the shot with
the Aerial Cinematographer, Aerial Coordinator
and Camera Ship Pilot will ensure a safe
and intelligent choice of helicopter for
all camera ship duties on the production. |
