under their control if aware the aircraft is at an altitude
believed to place the aircraft in unsafe proximity to
terrain, obstructions or other aircraft.
42.11Visual Approach
42.11.1Pilot
42.11.1.1If a visual approach is not desired, advises
ATC.
42.11.1.2Complies with controller’s instructions for
vectors toward the airport of intended landing or to a
visual position behind a preceding aircraft.

Nineteenth Edition Federal Aviation Administration
42.11.1.3 The pilot must, at all times, have either the
airport or the preceding aircraft in sight. After being
cleared for a visual approach, proceed to the airport
in a normal manner or follow the preceding aircraft.
Remain clear of clouds while conducting a visual
approach.
42.11.1.4 If the pilot accepts a visual approach
clearance to visually follow a preceding aircraft, you
are required to establish a safe landing interval behind
the aircraft you were instructed to follow. You are
responsible for wake turbulence separation.
42.11.1.5 Advise ATC immediately if the pilot is
unable to continue following the preceding aircraft,
cannot remain clear of clouds, needs to climb, or loses
sight of the airport.
42.11.1.6 Be aware that radar service is automatically
terminated, without being advised by ATC, when
the pilot is instructed to change to advisory frequency.
42.11.1.7 Be aware that there may be other traffic in
the traffic pattern and the landing sequence may differ
from the traffic sequence assigned by the approach
control or ARTCC.
42.11.2 Controller
42.11.2.1 Does not clear an aircraft for a visual
approach unless reported weather at the airport is
ceiling at or above 1,000 feet and visibility is 3 miles
or greater. When weather is not available for the
destination airport, informs the pilot and does not
initiate a visual approach to that airport unless there
is reasonable assurance that descent and flight to the
airport can be made visually.
42.11.2.2 Issues visual approach clearance when the
pilot reports sighting either the airport or a preceding
aircraft which is to be followed.
42.11.2.3 Provides separation except when visual
separation is being applied by the pilot.
42.11.2.4 Continues flight following and traffic
information until the aircraft has landed or has been
instructed to change to advisory frequency.
42.11.2.5 Informs the pilot when the preceding
aircraft is a heavy.
42.11.2.6 When weather is available for the
destination airport, does not initiate a vector for a
visual approach unless the reported ceiling at the
airport is 500 feet or more above the MVA and
visibility is 3 miles or more. If vectoring weather
minima are not available but weather at the airport is
ceiling at or above 1,000 feet and visibility of 3 miles
or greater, visual approaches may still be conducted.
42.11.2.7 Informs the pilot conducting the visual
approach of the aircraft class when pertinent traffic is
known to be a heavy aircraft.
42.12 Visual Separation
42.12.1 Pilot
42.12.1.1 Acceptance of instructions to follow
another aircraft or to provide visual separation from
it is an acknowledgment that the pilot will maneuver
the aircraft as necessary to avoid the other aircraft or
to maintain in-trail separation. Pilots are responsible
to maintain visual separation until flight paths
(altitudes and/or courses) diverge.
42.12.1.2 If instructed by ATC to follow another
aircraft or to provide visual separation from it,
promptly notify the controller if you lose sight of that
aircraft, are unable to maintain continued visual
contact with it, or cannot accept the responsibility for
your own separation for any reason.
42.12.1.3 The pilot also accepts responsibility for
wake turbulence separation under these conditions.
42.12.2 Controller Applies Visual Separation
Only:
42.12.2.1 Within the terminal area when a controller
has both aircraft in sight or by instructing a pilot who
sees the other aircraft to maintain visual separation
from it.
42.12.2.2 Pilots are responsible to maintain visual
separation until flight paths (altitudes and/or courses)
diverge.
42.12.2.3 Within en route airspace when aircraft are
on opposite courses and one pilot reports having seen
the other aircraft and that the aircraft have passed
each other.
