RUNWAY IN USE/ACTIVE RUNWAY/DUTY

RUNWAY− Any runway or runways currently being

used for takeoff or landing. When multiple runways

are used, they are all considered active runways. In

the metering sense, a selectable adapted item which

specifies the landing runway configuration or

direction of traffic flow. The adapted optimum flight

plan from each transition fix to the vertex is

determined by the runway configuration for arrival

metering processing purposes.
RUNWAY LIGHTS−

(See AIRPORT LIGHTING.)

RUNWAY MARKINGS−

(See AIRPORT MARKING AIDS.)

RUNWAY OVERRUN− In military aviation exclu-

sively, a stabilized or paved area beyond the end of a

runway, of the same width as the runway plus

shoulders, centered on the extended runway

centerline.
RUNWAY PROFILE DESCENT− An instrument

flight rules (IFR) air traffic control arrival procedure

to a runway published for pilot use in graphic and/or

textual form and may be associated with a STAR.

Runway Profile Descents provide routing and may

depict crossing altitudes, speed restrictions, and

headings to be flown from the en route structure to the

point where the pilot will receive clearance for and

execute an instrument approach procedure. A

Runway Profile Descent may apply to more than one

runway if so stated on the chart.

(Refer to AIM.)

RUNWAY SAFETY AREA− A defined surface

surrounding the runway prepared, or suitable, for

reducing the risk of damage to airplanes in the event

of an undershoot, overshoot, or excursion from the

runway. The dimensions of the RSA vary and can be

determined by using the criteria contained within

AC 150/5300-13,  Airport  Design,  Chapter 3.

Figure 3−1 in AC 150/5300-13 depicts the RSA. The

design standards dictate that the RSA shall be:

a. Cleared, graded, and have no potentially

hazardous ruts, humps, depressions, or other surface

variations;

b. Drained by grading or storm sewers to prevent

water accumulation;

c. Capable, under dry conditions, of supporting

snow removal equipment, aircraft rescue and

firefighting equipment, and the occasional passage of

aircraft without causing structural damage to the

aircraft; and,

d. Free of objects, except for objects that need to

be located in the runway safety area because of their

function. These objects shall be constructed on low

impact resistant supports (frangible mounted struc-

tures) to the lowest practical height with the frangible

point no higher than 3 inches above grade.

(Refer to AC 150/5300-13, Airport Design,

Chapter 3.)

RUNWAY STATUS LIGHTS (RWSL) SYSTEM−

The RWSL is a system of runway and taxiway

lighting to provide pilots increased situational

awareness by illuminating runway entry lights (REL)

when the runway is unsafe for entry or crossing, and

take-off hold lights (THL) when the runway is unsafe

for departure.

RUNWAY TRANSITION−

a. Conventional STARs/SIDs. The portion of a

STAR/SID that serves a particular runway or

runways at an airport.

b. RNAV STARs/SIDs. Defines a path(s) from

the common route to the final point(s) on a STAR. For

a SID, the common route that serves a particular

runway or runways at an airport.

RUNWAY USE PROGRAM− A noise abatement

runway selection plan designed to enhance noise

abatement efforts with regard to airport communities

for arriving and departing aircraft. These plans are

developed into runway use programs and apply to all

turbojet aircraft 12,500 pounds or heavier; turbojet

aircraft less than 12,500 pounds are included only if

the airport proprietor determines that the aircraft

creates a noise problem. Runway use programs are

coordinated with FAA offices, and safety criteria

used in these programs are developed by the Office of

Flight Operations. Runway use programs are

administered by the Air Traffic Service as “Formal”

or “Informal” programs.

a. Formal Runway Use Program− An approved

noise abatement program which is defined and

acknowledged in a Letter of Understanding between

Flight Operations, Air Traffic Service, the airport

proprietor, and the users. Once established, participa-

tion in the program is mandatory for aircraft operators

and pilots as provided for in 14 CFR Section 91.129.

b. Informal Runway Use Program− An approved

noise abatement program which does not require a
