- Know the basic structure of the atmosphere by:
- explaining the composition of the atmosphere;
- explaining the layers of the atmosphere;
- defining the ICAN standard atmosphere.
- Explain what is meant by:
- QNH; QFE; QNE; QFF;
- stability and temperature distribution;
- temperature gradients.
- Explain Buys Ballots law.
- Explain the different ways in which fog is formed as well as day and night visibility.
- Demonstrate and understand the purpose of the following instruments:
- Wet and dry-bulb thermometers.
- Barometer. Show that air has weight and pressure.
- Anemometer. Show that the wind has force and pressure.
- Windvane. Build a simple model of a wind vane.
- Rain gauge. Build a simple model of a rain gauge.
- Describe the measurement of inland and coastal station pressures and:
- Name the properties of ISOBARS.
- Describe the types of pressure distribution.
- Explain the variation in air pressure due to altitude, and point out some resulting problems for engines, for flight path hazards and for the pilot himself.
- Describe the composition of water vapour and explain: saturation; condensation; sublimation; evaporation; relative humidity; dew point and vapour pressure.
- Do the following:
- Define pressure gradient force and geostrophic wind.
- Discuss diurnal variation of the surface wind.
- Understand berg winds; sea breezes; land breezes; and indicate six or more ways how a pilot, about to land, can identify wind direction.
- Have passed the Airmanship Scoutcraft Badge, or complete parts 6 and 7 of its requirements.
- Make a simple forecast from a weather map with special reference to winds, temperature and barometric pressures.
- Understand the main forms of airframe icing and engine icing and explain the types of ice accretion in cloud: rime, clear ice, pack snow and freezing rain.
- Explain the effects of ice accretion on the performance of an aircraft.
- Report, either in writing or orally, on a visit to a meteorological station covering the following:
- instruments and their uses;
- charts used;
- instructions issued to pilots.
