Lesson 1-04 Airport Information Flashcards
Describe an active runway
The runway currently being used for takeoff and landing. If more than one is in use they are all active runways
Who dictates the active runway?
The controller decides the active runway
When would we choose from multiple potential active runways?
When there is calm wind
Or a wind that splits the runway
Low ceilings or thunderstorms from a certain direction
If the airport has parallel runways
Define Calm Wind Runway
Preferential runway for use in calm winds because it offers operational advantages like, length, approach, taxi distance or noise abatement.
When would we deviate from the current active runway?
YOu or the aircraft gain an operational advantage
You clearly indicate the wind speed and direction
What do you need to tell the pilot if you are using a runway with a tailwind?
Clearly indicate the wind speed and direction
Only if the tailwind component of the wind (including gusts) is less than 5 knots.
Runway is dry
What must wind speeds be to us the calm wind runway?
Less than 5 knots. If more than 5 knots assign the runway most closely aligned with wind direction
Define Operationally suitable runway
Runway must be long enough for the aircraft to use it.
If runway is too short planes may not want to use it even though the winds may favor it. IT may not be operationally suitable.
Define a crosswind
a wind that is 19 or 90 degrees to the runway that is in use.
Define a tailwind
When the angle of surface wind excedes 90 degrees in relation to the actvie runway.
What are operational advantages for a controller?
Anything that makes controlling easier
What are operational advantages for a pilot
Runway that saves tiem, fuel or is more convenient
Why are longer runways advantageous for arrivals? Departures?
More stopping distance
Less thrust reverse and braking
Less fuel consumption
Less wear and tear on the aircraft.
Length if takeoff must be aborted, less thrust usage for fuel efficiency
How long do runways have to be to have a wind sock on both ends?
3900’ or greater
Define operating surfaces?
Issue takeoffs and landing clearances to a fixed wing aircraft provided the operation takes place on a runway or another approved and designated area.
