ATSC 113 Flying Test Questions
and Answers All Correct
What happens if a pilot decides it is not safe to land? - Answer- pilot flies a "go around"
or an "aborted landing"
What is wind shear - Answer- change of wind speed/direction that comes with changes
in altitude
When does wind shear typically happen - Answer- it can occur at any altitude but it is
almost always present near the ground
Do aircrafts take off/land into or away from the wind - Answer- into the wind because it
reduces runway length required (take off quicker and slow down landing quicker)
what is the number on airport runway signify - Answer- the degrees from NORTH
clockwise rounded to nearest 10 degrees
* pilots try to land on a runway that is closest to the wind direction number
What does arrow for window direction signify - Answer- where the wind is COMING
FROM
What causes turbulence - Answer- - wind shear
- small eddies caused by air flow around small obstacles
- medium sized eddies associated with warm rising air
- large sized eddies associated with thunderstorms
What is ATMOSPHERIC STABILITY - Answer- whether air will stay TURBULENT
(unstable) or become/stay NON-TURBULENT (stable)
non turbulent AKA - Answer- LAMINAR
what does STATIC STABILITY depend on - Answer- temperature layering in the
atmosphere, NOT the wind
how does STATIC STABILITY work? - Answer- cool air is denser than warmer air.. so if
it is above warmer air then it wants to sink downwards and can create turbulent stability
(think warm air rises!)
, what happens as air moves up or down - Answer- pressure increases closer to the
ground
so as dense air moves down or warm air moves up then it experiences a pressure
change.. causing it to become more dense or less dense, precisely what it was trying to
avoid!
what are blobs of air called - Answer- AIR PARCELS
temperature change for vertically moving air parcels rate? - Answer- ADIABATIC
LAPSE RATE (9.8 degrees C/km)
where does statically stable conditions usually form? - Answer- near ground as ground
cools air
conversely if sun heats up ground then it will form statically unstable conditions
index for thunderstorms - Answer- CAPE (CONVECTIVE AVAILABLE POTENTIAL
ENERGY) - accumulated buoyant energy of a rising blob of warm air relative to cooler
surrounding air that it will be passing through
K INDEX (older) - look s a temperature, humidifiy, etc.
what is a SOUNDING - Answer- weather conditions at many differnt heights
* modern aircrafts have automated systems to make these measurements and relay
them via radio/staillite
* national weather services often launch weather balloons called RAWINSONDES
which sense temp/humiditiy/pressure and radio it back
what is a front - Answer- the boundary between warm/cool air
cold air advancing is a COLD FRONT
cold air retreating is a WARM FRONT
boundary between cold/warm air not moving a STATIONARY FRONT
cold front catching up with and merging to a warm front is a OCCLUDED FRONT
the boundary of air that is humid to air that is dry of roughly the same temperature is a
DRY LINE (dry air is denser the humid air)
they typically have clouds/precipitation/strong winds/turbulence
