A4A Calls Proposed PFC Hike Wasteful, Unnecessary
2014-03-13 05:00:00| Industrial Newsroom - All News for Today
Responding to rationale for Passenger Facility Charge (PFC) hike derived from FAA long-term forecast, Airlines for America's (A4A) Sharon Pinkerton called the move "a revenue grab." U.S. airports have ample resources to fund capital needs. These include investment-grade credit, "ample access" to bond market, $10.6 billion in unrestricted cash and investments (282 days of liquidity), and $4.7 billion in uncommitted funds from federal Airport and Airway Trust Fund.

Comprising 3- and 4-wire active (3 x 200 Vac to 3 x 480 Vac) harmonic filter modular systems, wall-mount Power Balance (PB-W) Series monitors current signal and compensates for unwanted elements of measured current. Scalable solutions, designed to meet IEEE-519, eliminate harmonic oscillations to improve power quality. Features include 21 µsec reactive power compensation, phase compensation current of 60–300 A extendable, harmonic correction to 50th order, and response time of <300 µsec.
