  24 Civil Aviation Order 40.2.1

 *3 Given air temperature in clear air or in cloud, determine approximate height of freezing level, using a temperature lapse rate of 3°C per 1 000 feet in clear air and 1.5°C in cloud.

 *4 Given pilot observations, either in clear air or in cloud, of any 1 or more of the following phenomena — turbulence, precipitation, temperature, cloud type predict the probability and likely duration of:

(a) airframe icing; and

(b) hail; and

(c) micro bursts and wind shear; and

(d) turbulence (including CAT).

 5 Use GPWT wind velocity data to:

(a) predict the probability of CAT; and

(b) identify forecast jetstream.

 *6 Recall the flying conditions likely to be associated with any phenomenon listed in meteorological documents enumerated in AIP MET. Flying conditions are defined as the descriptions given in Manual of Meteorology, Part 2.

 7 List the information provided by the Volmet service as detailed in AIP.

 8 For a radio navigation aid referred to in subparagraph 6.5 (b):

(a) understand the principles of operation, indications and limitations of the navigation aid; and

(b) extract from AIP:

 (i) the rated coverage of the radio navigation aids considering aircraft location, altitude and time of day; and

 (ii) pilot navigation tolerances.

 *9 For NDB bearings:

(a) predict the sense of the error caused by coastal refraction; and

(b) recall the fact that thunderstorms may cause unreliable bearings; and

(c) recall indications of station passage.

 *10 For VOR bearings:

(a) recall the cockpit indications of scalloping; and

(b) recall indications of station passage.

 11 Given heading and relative NDB bearings:

(a) calculate track to and from the NDB; and

(b) fix position given relative bearings of 2 stations; and

(c) calculate drift relative to planned track; and

(d) calculate the relative bearing which will indicate the aircraft is abeam a station; and

(e) calculate the relative bearing which will indicate that a desired track to or from an NDB has been intercepted, given the intercept heading; and

(f) calculate the heading to steer to intercept desired inbound track before reaching the NDB.

 12 State the VOR radial the aircraft is on given appropriate cockpit instrument indications including course needle indications of up to 4 dots from central.

 13 State VOR OBS settings required to provide command indications when flying on given tracks both to and from the VOR.
