h. Flight Visibility Below One Mile
When weather conditions are not officially reported at an airport and the pilot advises the flight
visibility is less than one statute mile, treat a request for SVFR operations at that airport by other
helicopters as follows:
(1) Inform departing aircraft that a clearance cannot be issued.
(2) Inform arriving aircraft operating outside the control zone that a clearance cannot be issued
unless an emergency exists.
(3) Ask an arriving aircraft operating within the control zone if he can depart the control zone
with a flight visibility of at least one statute mile. If the aircraft cannot depart or an emergency exists,
issue a clearance as soon as traffic conditions permit.
i. Special VFR Helicopter Separation or Local Procedures--Letter of Agreement Criteria
When warranted by the volume, complexity, or both of local helicopter operations, LOAs may
be used to specify alternate SVFR helicopter separation minima. Each LOA, however, shall, as a
minimum, specify that SVFR helicopters are to maintain visual reference to the surface and stick to the
following aircraft separation minima:
(1) Between Special Visual Flight Rule Helicopters
Separate by one mile. The separation may be reduced to 200 feet if--
(a) Both helicopters are departing at the same time on courses that diverge by at least 30
(b) You can determine this separation by reference to surface markings, or you instruct one
of the departing helicopters to remain at least 200 feet from each other.
(2) Between a Special Visual Flight Rule Helicopter and an Arriving or Departing Instrument
Flight Rule Aircraft
(a) If the arriving IFR aircraft is less than one mile from the landing airport, separate by one-
(b) If the IFR aircraft is one mile or more from the airport, separate by one mile.
