Topics covered in depth
Cold Front Passage
Wind, cloud, temperature and pressure sequence as a Southern Hemisphere cold front crosses an aerodrome.
CASR Part 61 MOS Schedule 3 (MT) 2.6.1 (p.505) — Typical flying weather associated with frontsVerified“Describe typical ‘flying weather’ associated with the following using the factors described in subclause 2.6.2: (a) cold fronts; (b) warm fronts; (c) wave depressions; (d) occluded fronts; (e) tropical cyclones; (f) the equatorial trough.”
CASR Part 61 MOS Schedule 3 (MT) 2.6.2 (p.505) — Fronts — temperature, wind, stability, cloud and precipitation changesVerified“For subclause 2.6.1, ‘flying weather’ embraces the following: (a) temperature (warmer/colder); (b) wind changes (back/veer, stronger/weaker); (c) stability and turbulence; (d) cloud type and approximate amount, precipitation.”
Standing lee waves, ACSL formation and the rotor zone downwind of a ridge in stable air.
CASR Part 61 MOS Schedule 3 (MT) 2.8.1 (p.507) — Meteorological phenomena — favourable conditions, recognition and effect on the aircraftVerified“With respect to the phenomena listed below in subclause 2.8.2, do the following: (a) state the conditions that are favourable to the development of the phenomenon and, where applicable, its dispersal; (b) recognise signs which may indicate the presence of each phenomenon; (c) describe the effect of the phenomenon on flight characteristics; (d) where applicable, state the pilot actions required.”
CASR Part 61 MOS Schedule 3 (MT) 2.8.2 (p.507) — Phenomena list including mountain waves and föhn windsVerified“The following is a list of meteorological phenomena that is for the purposes of subclause 2.8.1: (i) thermals, turbulence; (iii) wind gradient, wind shear and low-level jetstreams; (v) mountain waves and fohn winds; (ix) downdrafts associated with terrain/cloud.”
Common exam mistakes
Lenticular cloud is stationary while the air rushes through it.
The most severe turbulence is in the rotor beneath the crests, not in the smooth cloud.
Lee-side downdraughts can exceed a light aircraft’s maximum rate of climb.
