The purpose of this letter is to remind all rotorcraft users of the restrictions associated with the Brewster Pad located on Taxiway Z5. Due to the construction of a new hangar in 2015, north of taxiway “Z5”, both departure and approach is restricted to/from the south. The helipad is also restricted to D65 and smaller rotorcraft which includes those rotorcraft that are 65 feet in length or smaller.
