Section 1. General

6-1-1. DISTANCE

Use mileage-based (DME and/or ATD) procedures and minima only when direct pilot/controller VHF or UHF voice communications are maintained.

6-1-2. NONRECEIPT OF POSITION REPORT

When a position report affecting separation is not received, take action to obtain the report no later than 5 minutes after the aircraft was estimated over the fix.

6-1-3. DUPLICATE POSITION REPORTS

Do not require an aircraft to make the same position report to more than one facility.

6-1-4. ADJACENT AIRPORT OPERATION

TERMINAL

1. The ATC facility having control jurisdiction at adjacent airports must separate arriving or departing IFR aircraft on a course that will cross the flight path of an aircraft requiring wake turbulence separation in accordance with the following:
   1. Category B, C, D, E, F, G, H, or I aircraft behind Category A aircraft - 3 minutes.
   2. Category B, C, D, E, F, G, H, or I aircraft behind Category B or D aircraft - 2 minutes.
   3. Category E, F, G, H, or I aircraft behind Category C aircraft - 2 minutes.
   4. Category I aircraft behind Category E aircraft - 2 minutes.
2. EN ROUTE.The ATC facility having control jurisdiction at adjacent airports must separate arriving or departing IFR aircraft on a course that will cross the flight path of an aircraft requiring wake turbulence separation in accordance with the following:
   1. Heavy, large, or small behind super - 3 minutes.
   2. Heavy, large, or small behind heavy - 2 minutes.
   3. Small behind B757 - 2 minutes.
