Business aircraft cabins are generally not quiet. Not with the turbulent boundary-layer rush of air around the fuselage at Mach 0.85 and the whine of a couple of jet engines no great distance from the comfy chairs. Then there are the pumps, hydraulics, fans, gears, actuators, electric motors, worn bearings and air distribution through the metal ductwork, not to mention the occasional hum of the microwave and induction oven, the rattling of glasses and flatware in the galley and that giant sucking sound coming from the lavatory.
The U.S. Court of Appeals has unanimously upheld the FAA’s right to impose the mandatory overwater North Shore Route on helicopter traffic over New York’s Long Island. Writing for the Court, U.S. circuit judge Richard Roberts rejected a legal challenge (petition for review) to the route filed by the Helicopter Association International to overturn the mandate.
As part of a growing suite of noise- and pollution-control measures, France’s Nice Cote D’ Azur Airport will invest in the installation of a new underground power system that will reduce business jets’ dependency on auxiliary power units on the ramp. The system, the first of its kind in Europe, provides hatches under each aircraft engine start-up stand for access to a centralized power and heating/cooling system, greatly reducing the number of APU operation hours, as well as reducing exhaust emissions. The $2.7 million project is expected to begin this summer.
An Environmental Good Conduct Code is now in place at popular Cannes Mandelieu Airport and signed by multiple stakeholders, including the French DGAC, numerous civil aircraft operators, air traffic controllers, airport tenants and various local environmental groups.
The code is voluntary, addresses primarily noise-control issues and calls for the signers to “respect the quality of the environment at and around l’Aéroport Cannes Mandelieu.”
The FAA’s final rule on civil tiltrotor noise limits and conditions for noise compliance measurement becomes effective March 11. It amends regulations governing noise certification standards and establishes new noise limits and procedures to ensure that noise-reduction technology is incorporated in tiltrotors.
NBAA is welcoming International Civil Aviation Organization (ICAO) committee proposals to limit aircraft emissions and reduce noise levels in the near term. The Committee on Aviation Environmental Protection (CAEP) at ICAO wrapped up three years of work last Thursday with recommendations for creating both a metric and standards for carbon-dioxide emissions, as well as for reducing aircraft noise levels by 2020.
The reintroduced Los Angeles Residential Helicopter Noise Relief Act has little chance of being enacted, according to government information website GovTrack.us. S.208 seeks to force the FAA to impose regulations governing helicopter operations in the Los Angeles area. GovTrack.us estimates that the bill has a 4-percent chance of getting out of committee and a 1-percent chance of being enacted.
TAG Aviation has introduced a new measure to manage noise at the UK’s Farnborough Airport. Since January 1, jet aircraft that do not meet the ICAO Chapter/Stage IV standard have been banned from using the airport. This noise standard is ICAO’s most stringent and quietest classification for jet aircraft. To ensure compliance, TAG requires approved noise certificates before permission can be granted to land or take off at the airport. Approximately 300 movements last year would not meet the new standard, it said.
The FAA has issued a notice of proposed rulemaking (NPRM) aimed at reducing noise generated by new helicopters and supplemental type certificate (STC) modifications for new helicopters certified under Part 36 (noise standards) of the federal aviation regulations (FARs).
