5-8-5. DEPARTURES AND ARRIVALS ON PARALLEL OR NONINTERSECTING DIVERGING RUNWAYS
TERMINAL. Authorize simultaneous operations between an aircraft departing on a
runway and an aircraft on final approach to another parallel or nonintersecting diverging runway if the departure
course diverges immediately by at least 30 degrees from the missed approach course until separation is applied and
provided one of the following conditions is met:
NOTE: When one or both of the takeoff/landing surfaces is a helipad, consider the helicopter takeoff
course as the runway centerline and the helipad center as the threshold.
When parallel runway thresholds are even, the runway centerlines are at least 2,500 feet apart. (See FIG 5-8-10
and FIG 5-8-11.)
FIG 5-8-10 Parallel Thresholds are EvenFIG 5-8-11 Parallel Thresholds are Even
When parallel runway thresholds are staggered and:
The arriving aircraft is approaching the nearer runway: the centerlines are at least 1,000 feet apart and
the landing thresholds are staggered at least 500 feet for each 100 feet less than 2,500 the centerlines are
separated. (See FIG 5-8-12 and FIG 5-8-13.)
FIG 5-8-12 Parallel Thresholds are StaggeredFIG 5-8-13 Parallel Thresholds are Staggered
NOTE: In the event of a missed approach by an aircraft requiring wake turbulence separation
behind it, apply the procedures in Paragraph 3-9-6, Same Runway Separation and/or Paragraph 3-9-8,
Intersecting Runway/Intersecting Flight Path Operations to ensure that the larger aircraft does not overtake
or cross in front of an aircraft departing from the adjacent parallel runway.
The arriving aircraft is approaching the farther runway: the runway centerlines separation exceeds 2,500
feet by at least 100 feet for each 500 feet the landing thresholds are staggered. (See FIG 5-8-14.)
FIG 5-8-14 Parallel Thresholds are Staggered
When nonintersecting runways diverge by 15 degrees or more and runway edges do not touch. (See FIG 5-8-15.)
FIG 5-8-15 Diverging Nonintersecting Runways
When the aircraft on takeoff is a helicopter, hold the helicopter until visual separation is possible or apply
the separation criteria in subparas a, b, or c.
