Airport Operations


Of vital importance is the need for pilots to

notify the controller when difficulties are encoun-

tered or at the first indication of becoming

disoriented. Pilots should proceed with extreme

caution when taxiing toward the sun. When vision

difficulties are encountered pilots should

immediately inform the controller.


Advisory Circular 120−57, Surface Movement

Guidance and Control System, commonly known as

SMGCS (pronounced “SMIGS”) requires a low

visibility taxi plan for any airport which has takeoff

or landing operations in less than 1,200 feet runway

visual range (RVR) visibility conditions. These plans,

which affect aircrew and vehicle operators, may

incorporate additional lighting, markings, and

procedures to control airport surface traffic. They

will be addressed at two levels; operations less than

1,200 feet RVR to 600 feet RVR and operations less

than 600 feet RVR.


Specific lighting systems and surface markings may be
found in paragraph 2

−1−11, Taxiway Lights, and

paragraph 2

−3−4, Taxiway Markings.


When low visibility conditions exist, pilots

should focus their entire attention on the safe

operation of the aircraft while it is moving. Checklists

and nonessential communication should be withheld

until the aircraft is stopped and the brakes set.



20. Exiting the Runway After Landing

The following procedures must be followed after

landing and reaching taxi speed.


Exit the runway without delay at the first

available taxiway or on a taxiway as instructed by

ATC. Pilots must not exit the landing runway onto

another runway unless authorized by ATC. At

airports with an operating control tower, pilots should

not stop or reverse course on the runway without first

obtaining ATC approval.


Taxi clear of the runway unless otherwise

directed by ATC. An aircraft is considered clear of the

runway when all parts of the aircraft are past the

runway edge and there are no restrictions to its

continued movement beyond the runway holding

position markings. In the absence of ATC instruc-

tions, the pilot is expected to taxi clear of the landing

runway by taxiing beyond the runway holding

position markings associated with the landing

runway, even if that requires the aircraft to protrude

into or cross another taxiway or ramp area. Once all

parts of the aircraft have crossed the runway holding

position markings, the pilot must hold unless further

instructions have been issued by ATC.


1. The tower will issue the pilot instructions which will
permit the aircraft to enter another taxiway, runway, or
ramp area when required.

2. Guidance contained in subparagraphs a and b above is
considered an integral part of the landing clearance and
satisfies the requirement of 14 CFR Section 91.129.


Immediately change to ground control fre-

quency when advised by the tower and obtain a taxi



1. The tower will issue instructions required to resolve any
potential conflictions with other ground traffic prior to
advising the pilot to contact ground control.

2. Ground control will issue taxi clearance to parking.
That clearance does not authorize the aircraft to “enter”
or “cross” any runways. Pilots not familiar with the taxi
route should request specific taxi instructions from ATC.



21. Practice Instrument Approaches


Various air traffic incidents have indicated the

necessity for adoption of measures to achieve more

organized and controlled operations where practice

instrument approaches are conducted. Practice

instrument approaches are considered to be instru-

ment approaches made by either a VFR aircraft not on

an IFR flight plan or an aircraft on an IFR flight plan.

To achieve this and thereby enhance air safety, it is

Air Traffic’s policy to provide for separation of such

operations at locations where approach control

facilities are located and, as resources permit, at

certain other locations served by ARTCCs or parent

approach control facilities. Pilot requests to practice

instrument approaches may be approved by ATC

subject to traffic and workload conditions. Pilots

should anticipate that in some instances the controller

may find it necessary to deny approval or withdraw

previous approval when traffic conditions warrant. It

must be clearly understood, however, that even

though the controller may be providing separation,

pilots on VFR flight plans are required to comply with

basic VFR weather minimums (14 CFR Sec-

tion 91.155). Application of ATC procedures or any

action taken by the controller to avoid traffic

conflictions does not relieve IFR and VFR pilots of
