Rotary-Wing Landing Pads, Surfaced
A paved surface for takeoffs and landings of rotary-wing aircraft. It is physically
smaller than a rotary-wing runway and is normally located at a site that is remote
from an airfield or heliport. From and operational point of view, the helipad includes
the prepared landing surface and shoulders, plus various cleared areas and airspace.
For inventory purposes, only the prepared surface is included.
Helipads designed and constructed for vertical takeoff and landing of helicopters will
be authorized for isolated sites, for support of infrequent operation requirements, for
sites which cannot physically support limitations of land and/or airspace or
economically justify airfield/heliport development, or at airfield/heliports with high
air traffic density which require one or more helipads for establishment of safe
aircraft traffic control patterns. Where several helipads are required to serve adjacent
high density parking areas, they may be connected by airfield pavement for more
rapid landing and takeoff operations. Helipads so connected may be referred to as
"helicopter landing strips", or "lanes", not to be confused with helicopter runways.
Helipad criteria is applicable to these type facilities.
One helipad is allowed at Hospitals.
Basic dimensions are 30 m by 30 m [100 ft by 100 ft].
Stabilized shoulders will be provided around helipads and along any connecting
pavements.
11131
Rotary-Wing Landing Pads, Unsurfaced
An unpaved prepared surface which is, centered within a clear area, and used
exclusively for training, emergency, and other special landing and takeoff operations
of rotary-wing aircraft. From an operational point of view, the helipad includes the
prepared landing surface and shoulders, plus various cleared areas and airspace. For
inventory purposes, only the prepared surface is included.
