Ch 4B - Airports Flashcards
Radio required to operate in a controlled airport environment
Two-way radio; since all aircraft in the vicinity, as well as those on the ground, are subject to instructions issued from the control tower
Control of VFR traffic is
Not exercised at an uncontrolled airport
The number at the end of the runway corresponds to the
Magnetic direction that you are heading when taking off or landing on that runway
Used at most airports to ensure that air traffic flows in an orderly manner
Standard rectangular pattern with 5 named legs
Most common wind direction indicator is
Wind sock; used at both controlled and uncontrolled airports
A tetrahedron is a
Landing direction indicator that may swing around with the small end pointing into the wind, or it may be positioned to show landing direction
The segmented circle
Helps to identify the location of the wind direction indicator and employs landing strip indicators in conjunction with traffic pattern indicators to show traffic pattern turn direction for a given runway
A visual runway normally is marked only with
The runway number and dashed white centerline
IFR runways can have additional markings
Threshold markings (thick parallel lines), touchdown zone (small lines), and aiming point (solid block)
Usually, a runway has a displaced threshold because of
An obstruction off the end of the runway that might prohibit a normal descent and landing on the beginning portion of the pavement; solid white line in front of threshold markings with arrows leading up to it; can still be used for taxi, rollout, takeoffs
A blast pad/stop way area is an area
Where propeller or jet blast can dissipate without creating a hazard to others; cannot be used for taxi/land/takeoff; big yellow chevrons
Taxiways normally have
Yellow centerlines and hold lines whenever they intersect with a runway
6 basic airport signs
Mandatory (red), location (blck w/ yellow), direction (yellow w/arrow&letter), destination (yellow w/arrow&word), information (yellow), and runway distance remaining (black w/white)
Pilot controlled lighting
Key mike on frequency; 7= max intensity, 5=medium, 3=low intensity
Closed runway marked by
Yellow X
LAHSO clearance
Land and hold short operations; no student pilot; visibility > 3 miles and ceiling >1,000 ft
An airport rotating beacon operating during daylight hours normally indicates
The weather is below VFR minimums
Military airport beacon
Two quick white flashes between green flashes
VASI
Visual approach slope indicator; both white=too high, both red=too low, red above white= on glide path
PAPI
Precision approach path indicator; 4 white= too high, 4 red= too low, two white then two red= on glide path
Blue lights
Edge of the taxiway
