Arrival Procedures

FIG 5−4−27

4. RNP Converging Runway Operations. At

airports where runways converge, but may or may not

intersect, an RNP AR approach can provide a precise

curved missed approach path that conforms to aircraft

separation minimums for simultaneous operations

(See FIG 5−4−28). By flying this curved missed

approach path with high accuracy and containment

provided by RNP, dual runway operations may

continue to be used to lower ceiling and visibility

values than currently available. This type of

operation allows greater capacity at airports where it

can be applied.

FIG 5−4−28

5−4−19. Side−step Maneuver

a. ATC may authorize a standard instrument

approach procedure which serves either one of

parallel runways that are separated by 1,200 feet or

less followed by a straight−in landing on the adjacent

runway.

b. Aircraft that will execute a side−step maneuver

will be cleared for a specified approach procedure

and landing on the adjacent parallel runway.

Example, “cleared ILS runway 7 left approach,

side−step to runway 7 right.” Pilots are expected to

commence the side−step maneuver as soon as

possible after the runway or runway environment is

in sight. Compliance with minimum altitudes

associated with stepdown fixes is expected even after

the side−step maneuver is initiated.

NOTE−

Side−step minima are flown to a Minimum Descent

Altitude (MDA) regardless of the approach authorized.

c. Landing minimums to the adjacent runway will

be based on nonprecision criteria and therefore higher

than the precision minimums to the primary runway,

but will normally be lower than the published circling

minimums.
5−4−20. Approach and Landing Minimums

a. Landing Minimums. The rules applicable to

landing minimums are contained in 14 CFR

Section 91.175. TBL 5−4−1 may be used to convert

RVR to ground or flight visibility. For converting

RVR values that fall between listed values, use the

next higher RVR value; do not interpolate. For

example, when converting 1800 RVR, use 2400 RVR

with the resultant visibility of 

1

/

2

mile.

b. Obstacle Clearance. Final approach obstacle

clearance is provided from the start of the final

segment to the runway or missed approach point,

whichever occurs last. Side−step obstacle protection

is provided by increasing the width of the final

approach obstacle clearance area.
