c) Area Agreements. See HSAC Area Agree-ment Maps for operating procedures for onshore high density traffic locations.
NOTE.
Pilots of helicopters operating VFR above 3,000 feet above the surface should refer to the current Federal Aviation Regulations (14 CFR Part 91), and Section ENR 1.4, Paragraph 1.7, Basic VFR Weather Minimums, of the AIP.
FIG ENR 6.2.2
Closed Helideck Marking
Federal Aviation Administration Twentieth Edition
d) Landing Lights. Aircraft landing lights should be on to enhance aircraft identification:
1) During takeoff and landings;
2) In congested helicopter or fixed wing traffic areas;
3) During reduced visibility; or,
4) Anytime safety could be enhanced.
1.11 Offshore Helidecks/Landing Communica-tions
1.11.1 Background. To enhance safety, and pro-vide appropriate time to prepare for helicopter operations, the following is recommended when anticipating a landing on an offshore helideck.
1.11.2 Recommended Practices
1.11.2.1 Before landing on an offshore helideck, pilots are encouraged to establish communications with the company owning or operating the helideck if frequencies exist for that purpose.
1.11.2.2 When impracticable, or if frequencies do not exist, pilots or operations personnel should attempt to contact the company owning or operating the helideck by telephone. Contact should be made before the pilot departs home base/point of departure to advise of intentions and obtain landing permission if necessary.
NOTE.
It is recommended that communications be established a minimum of 10 minutes prior to planned arrival time. This practice may be a requirement of some offshore owner/operators.
NOTE.
1.
See subparagraph 1.4 for Tanker Operations.
2.
Private use Heliport. Offshore heliports are privately owned/operated facilities and their use is limited to persons having prior authorization to utilize the facility.
1.12 Two (2) Helicopter Operations on Offshore Helidecks
1.12.1 Background. Standardized procedures can enhance the safety of operating a second helicopter on an offshore helideck, enabling pilots to determine/maintain minimum operational parame-ters. Orientation of the parked helicopter on the helideck, wind and other factors may prohibit multi.helicopter operations. More conservative Rotor Diameter (RD) clearances may be required under differing condition, i.e. temperature, wet deck, wind (velocity/direction/gusts), obstacles, approach/ departure angles, etc. Operations are at the pilot’s discretion.
1.12.2 Recommended Practice. Helideck size, structural weight capability, and type of main rotor on the parked and operating helicopter will aid in determining accessibility by a second helicopter. Pilots should determine that multi.helicopter deck operations are permitted by the helideck owner/oper-ator.
1.12.3 Recommended Criteria
1.12.3.1 Minimum one.third rotor diameter clearance (1/3 RD). The landing helicopter main-tains a minimum 1/3 RD clearance between the tips of its turning rotor and the closest part of a parked and secured helicopter (rotors stopped and tied down).
1.12.3.2 Three foot parking distance from deck edge (3’). Helicopters operating on an offshore helideck land or park the helicopter with a skid/wheel assembly no closer than 3 feet from helideck edge.
1.12.3.3 Tiedowns. Main rotors on all helicopters that are shut down be properly secured (tied down) to prevent the rotor blades from turning.
1.12.3.4 Medium (transport) and larger helicopters should not land on any offshore helideck where a light helicopter is parked unless the light helicopter is property secured to the helideck and has main rotor tied down.
1.12.3.5 Helideck owners/operators should ensure that the helideck has a serviceable anti.skid surface.
1.12.4 Weight and limitations markings on helideck. The helideck weight limitations should be displayed by markings visible to the pilot (see State of Louisiana “Offshore Heliport Design Guide” and FAA Advisory Circular AC 150/ 5390.2A, Heliport Design Guide).
NOTE.
Some offshore helideck owners/operators have restrictions on the number of helicopters allowed on a helideck. When helideck size permits, multiple (more than two) helicopter operations are permitted by some operators.
1.13 Helicopter Rapid Refueling Procedures (HRR)
1.13.1 Background. Helicopter Rapid Refueling (HRR), engine(s)/rotors operating, can be conducted safely when utilizing trained personnel and observing safe practices. This recommended practice provides minimum guidance for HRR as outlined in National Fire Protection Association (NFPA) and industry practices. For detailed guidance, please refer to National Fire Protection Association (NFPA) Docu-ment 407, “Standard for Aircraft Fuel Servicing,” 1990 edition, including 1993 HRR Amendment.
