1. Transfer of heat energy - Conduction - Correct Answer: The transfer of
heat via contact - the hotter object transfer heat energy to the cooler object
2. Transfer of heat energy - Convection - Correct Answer: The distribution
of hot air/water via the process of the hot air/water rising and the cooler air
sinking
3. Transfer of heat energy - Radiation - Correct Answer: The transfer of
heat through electromagnetic radiation in the infra-red frequency range.
4. -Solar Radiation: received from the sun - emitted in short wave radiation
-Terrestrial Radiation: emitted by the warmed Earth back into space - long
wave radiation
5. Greenhouse effect: gasses and clouds in the atmosphere will reflect
terrestrial radiation back to the surface, warming the atmosphere
6. Transfer of heat energy - Advection - Correct Answer: The horizontal
movement of air masses.
,7. Transfer of heat energy - Latent Heat - Correct Answer: Absorption and
release of heat energy through evaporation, freezing and condensing of
water
Sublimation:
Ice -> Vapour
Absorbing Latent Heat:
- Ice -> Water -> Vapour
Deposition:
- Vapour -> Ice
Releasing Latent Heat:
- Vapour -> Water -> Ice
8. What does a Stevenson screen do? - Correct Answer: Measures
temperature using a thermometer at 1m above the ground
9. What is an inversion? - Correct Answer: Layer in which the temperature
increases with height - ELR is negative
10.What is an isotherm? - Correct Answer: A line that connects points of
equal temperature - ELR remains constant with altitude
,11.What is an isobar? - Correct Answer: Line on a weather chart which
connects areas of equal/constant barometric pressure
Can depict wind strength (pressure gradient) and direction
12.What is meant by pressure gradient? - Correct Answer: horizontal rate
of pressure change. Strong pressure gradient = strong winds
13.What is relative humidity? - Correct Answer: The ratio between the
amount of H2O in given volume of gas and the maximum amount it is
capable of holding at that temperature.
14.How does air density affect aircraft performance? And factors affecting air
density? - Correct Answer: Low air density reduces lift, thrust and drag.
Power available is reduced
T/O and landing distances are increased
Crew performance is affected
Factors:
Temperature - increased temperature will reduce air density
Pressure - reduced air pressure will reduce air density
Humidity - increased humidity will reduce air density
15.Height definition - Correct Answer: The vertical distance above some
specific datum (AGL)
, 16.Altitude definition - Correct Answer: The vertical distance above MSL
17.Elevation definition - Correct Answer: Vertical distance above MSL of
some point on the ground
18.QNH - Correct Answer: Altimeter Setting for Altitude Above Sea Level
19.QFE - Correct Answer: Height above airport elevation (or runway
threshold elevation) based on local station pressure
20.Pressure Height (and equation) - Correct Answer: The height in the
International Standard Atmosphere (ISA) using 1013.25hPa
Pressure Height = (1013-QNH) x 30 + elevation (or current altitude)
21.Composition of the Atmosphere - Correct Answer: 78% nitrogen, 21%
oxygen, 1% other gases
22.Layers of the atmosphere - Correct Answer: troposphere (and
tropopause), stratosphere (and stratopause) , mesosphere (and
mesopause), thermosphere, exosphere
23.The troposphere - Correct Answer: The layer where temperature drops
with increasing height.
