designed to alert others to the potential hazard. Since
this is a voluntary program, exercise caution and do
not rely solely on the rotating beacon as an indication
that aircraft engines are in operation.
e. Prior to commencing taxi, it is recommended to
turn on navigation, position, anti-collision, and logo
lights (if equipped). To signal intent to other pilots,
consider turning on the taxi light when the aircraft is
moving or intending to move on the ground, and
turning it off when stopped or yielding to other
ground traffic. Strobe lights should not be illuminated
during taxi if they will adversely affect the vision of
other pilots or ground personnel.
f. At the discretion of the pilot-in-command, all
exterior lights should be illuminated when taxiing on
or across any runway. This increases the conspicu-
ousness of the aircraft to controllers and other pilots
approaching to land, taxiing, or crossing the runway.
Pilots should comply with any equipment operating
limitations and consider the effects of landing and
strobe lights on other aircraft in their vicinity.
g. When entering the departure runway for takeoff
or to "line up and wait," all lights, except for landing
lights, should be illuminated to make the aircraft
conspicuous to ATC and other aircraft on approach.
Landing lights should be turned on when takeoff
clearance is received or when commencing takeoff
roll at an airport without an operating control tower.

4-3-24. Flight Inspection/‘Flight Check'
Aircraft in Terminal Areas
a. Flight check is a call sign used to alert pilots and
air traffic controllers when a FAA aircraft is engaged
in flight inspection/certification of NAVAIDs and
flight procedures. Flight check aircraft fly preplanned

high/low altitude flight patterns such as grids, orbits,
DME arcs, and tracks, including low passes along the
full length of the runway to verify NAVAID
b. Pilots should be especially watchful and avoid
the flight paths of any aircraft using the call sign
"Flight Check." These flights will normally receive
special handling from ATC. Pilot patience and
cooperation in allowing uninterrupted recordings can
significantly help expedite flight inspections, mini-
mize costly, repetitive runs, and reduce the burden on
the U.S. taxpayer.
