Flight Environment Pt.3 Flashcards
Airport lighting to wind indicators
They are standardized so that airports use the same light colors for runways and taxiways
Airport Lighting
They help a pilot identify an airport at night. They are normally operated from dusk until dawn
Airport beacons
Airport beacons are turned on if the ceiling is less than ___________ and/or ground visibility is less than ________________ (VFR minimums)
1,000 feet, 3 statute miles
This may be an omnidirectional capacitor-discharge device, or it may rotate at a constant speed, that produces the visual effect of flashes at regular intervals
Airport beacons
What are the airport beacon light colors for civilian land airports?
flashing white and green
What are the airport beacon light colors for water airport?
flashing white and yellow
What are the airport beacon light colors for heliport?
Flashing white, yellow, and green for heliport
What are the airport beacon light colors for a military airport
two quick white flashes alternating with a green flash
They are primarily intended to provide a means to transition from instrument flight to visual flight for landing.
Approach light systems
They provide the pilot with glidepath information that can be used for day or night approaches
Visual Glideslope indicators
By maintaining the proper glidepath as provided by the system, a pilot should have adequate obstacle clearance and should touch down within a specified portion of the runway
Visual Glideslope Indicators
This is a system of lights arranged to provide visual descent guidance during an approach
Visual Approach Slope Indicator
State the three phrases for visual approach slope indicator
Red over white, you’re alright
White over White, high as a kite
Red over red, you’re dead
This is a tri-color system consists of a single- light unit projecting a three-color visual approach path
Visual Approach Slope Indicator
State the visual approach slope indicator colors
Red: Below the glidepath
Green: on the glidepath
Amber: above the glidepath
They usually consist of a single-light unit projecting a two-color visual approach path into the final approach area of the runway
Pulsating VASIs
What does steady white mean?
on glidepath
What does steady red mean?
slightly below glidepath
What does pulsating red mean?
below the glidepath
What does pulsating white mean?
above glidepath
This uses lights similar to the VASI system, except they are installed in a single row, normally on the left side of the runway
Precision Approach Path Indicator
They are installed at many airfields to provide rapid and positive identification of the approach end of a particular runway
Runway end identifier lights (REIL)
