Airport Base Operations Flashcards
Chevrons
Yellow markings aligned with the runway that show pavement areas that are unusable for landing, takeoff, and taxing.
Blast-Pad, Stop-Way, Overrun Area
Demarcation Bar
Yellow bar that delineates a runway with a displaced threshold from a blast pad, stop-way, or taxiway that precedes the runway.
Displaced Threshold
A threshold located at a point on the runway other than the designated beginning of the runway.
What does a Displaced Threshold reduce?
Reduces the runway length available for landings.
What can a Displaced Threshold be used for?
Takeoff.
Landings from the opposite direction.
Runway Threshold Bar
White bar that delineates the beginning of the runway that is available for landing when the threshold has been relocated or displaced.
What do Runway Threshold Markings identify?
The beginning of runway that is available for landing.
How many Runway Threshold Marking stripes are there?
What do Runway Threshold Markings look like?
Stripes of uniform dimensions.
The number of stripes is related to the width of the runway.
What are the dimensions of Runway Threshold Markings?
150 feet long and 5.75 feet wide
Runway Number and Designation
Determined from the approach direction.
White, whole number of the magnetic azimuth of the centerline of the runway clockwise from magnetic north.
The letter differentiates between left (L), right (R), or center (C) parallel runways, if applicable.
Runway Centerlines
Identifies the center of the runway with white lines and provides alignment guidance during takeoff and landings.
What do Runway Touchdown Zone Markings do?
Identifies the touchdown zone for aircraft.
What do Runway Touchdown Zone Markings look like?
Groups of one, two, and three white rectangular bars symmetrically arranged in pairs about the runway centerline.
How far apart are Runway Touchdown Zone Markings spaced?
Spaced in 500 feet increments.
Aiming Point Markings
Two rectangular white markings consisting of a broad white stripe located on each side of the runway centerline and approximately 1,000 feet from the landing threshold.
Serve as a visual aiming point for landing aircraft.
Runway Edge Lines
Delineates the edges of the runway by providing a white visual contrast between the runway and the terrain or shoulders.
Standard Traffic Pattern
A rectangular pattern consisting of upwind, crosswind, downwind, base, and final legs.
Turns are always to the left unless otherwise noted.
The standard pattern altitude is 1000 feet AGL.
What does PAPI stand for?
Precision Approach Path Indicator.
What is a PAPI?
Light units arranged in a single bar to indicate if an approach is above or below the glide path.
What does VASI stand for?
Visual Approach Slope Indicator.
What is a VASI?
Light units arranged in bars to indicate if an approach is above or below the glide path.
What does REIL stand for?
Runway End Identifier Lights
What are REILs?
A pair of synchronized white flashing lights located on each side of the runway threshold.
Provide rapid and positive identification of the approach end of a runway.
Taxiway Lights
Blue omnidirectional lights that outline the edges of the taxiway.
Runway Edge Lights
White lights used to outline the edges of runways at night or during low visibility conditions. Can be set to low, medium, or high-intensity.
Runway End Lights
Red lights that mark the end of the runway.
Which leg of the traffic pattern are you in immediately after takeoff?
Upwind.
Which leg of the traffic pattern comes after upwind?
Crosswind.
Which leg of the traffic pattern comes after crosswind?
Downwind.
Which leg of the traffic pattern comes after downwind?
Base.
Which leg of the traffic pattern comes after base?
Final.
