Hi all,

I attempted irex earlier this year and failed..
My books and maps were from 2013 so that probably didnt help.

Anyway i thought i would post my KDR's and maybe someone could give me some pointers in those areas.
I plan to sit it again at the end of the year.
Thanks for the help i have written a sentence on each one if I can shed any more light.

1. Privileges/Limitations of endorsements
2.3.1 Operation and limitations of flight instruments required to conduct a flight under the IFR
[color=purple]I cant remember this question must have read wrong reference[/color]

2. Alt planning lighting requirements
4.2.1 Describe the alternate aerodrome requirements for the following:
(a) weather;
(b) navigation aids or approach procedures;
(c) aerodrome lighting (including personnel in attendance requirements);
(d) availability of weather reports;
(e) divert time.
[color=purple]I think this was a lighting question[/color]

3. Select cruise level lsalt freezing
4.1.1 Plan an IFR flight between aerodromes in Australia in accordance with the requirements specified in AIP and considering the following:
(a) route limitations;
(b) aircraft performance and forecast freezing level;
(c) table of cruising altitudes/levels.

[color=purple]This was a freezing level question, what the go can you plan to fly above freezing level?[/color]

4. know total fuel req
4.2.2 Determine holding fuel requirements for:
(a) weather; and
(b) traffic;
[color=purple]Not sure
[/color]
5. Weather forecast requirements
3.2.1 Requirements for obtaining meteorological information to conduct a flight under the IFR.
[color=purple]Not sure[/color]

6. Operation of PAL
2.3.16 Procedure/s for operating PAL systems.
[color=purple]Read the wrong page on the ERSA [/color]

7. SID radar procedure
2.3.18 Pilot responsibilities for compliance with the following procedures:
(a) SID;
(b) STAR;
(c) Noise abatement;
(d) Missed approach;
(e) Holding pattern and entry.
[color=purple]Not sure[/color]

8. assess ADF indication
5.1.2 For lateral azimuth guidance provided by NDB, describe the following:
(a) the errors caused by coastal refraction;
(b) the effect thunderstorms may cause;
(c) the indications of loss of signal integrity;
(d) the potential for errors when turning;
(e) the indications of station passage.
[color=purple]Not sure[/color]

9. Thunderstorm and hail
3.2.4 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 the following:
(a) airframe icing;
(b) hail;

[color=purple]I always though you were to fly to the upwind side to avoid hail if going close to a thunderstorm however the casa question didn’t have this as an option :S[/color]

(c) micro bursts and wind shear;
(d) turbulence (including CAT).

10. know require track intercepted from ADF BRG
More practice of ADF’s
5.1.3 Given heading and relative NDB azimuth bearings, for the following:
(a) calculate track to and from the NDB;
(b) fix position given relative bearings of 2 stations;
(c) calculate drift relative to planned track;
(d) calculate the relative bearing which will indicate the aircraft is abeam a station;
(e) calculate the relative bearing which will indicate that a desired track to or from an NDB has been intercepted, given the intercept heading;
(f) calculate the heading to steer to intercept desired inbound track before reaching the NDB.
[color=purple]More practice of ADF’s[/color]

11. dest fuel state wx tfc
4.2.1 Describe the alternate aerodrome requirements for the following:
(a) weather;
(b) navigation aids or approach procedures;
(c) aerodrome lighting (including personnel in attendance requirements);
(d) availability of weather reports;
(e) divert time.

[color=purple]Not sure[/color]

12. NDB approach altitude limitations
5.1.1 For ground-based radio navigation aids:
(a) understand the principles of operation, indications and limitations of the ground-based navigation aids; 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.
[color=purple]Not sure[/color]

13. CTA visual approach procedures
4.3.6 The requirements that must be satisfied for descent below LSALT or minimum safety altitude by day and night under the IFR and night VFR.
[color=purple]Not sure
[/color]
14. Circling obstacle clearance
4.3.3 The minimum obstacle clearance provided by the minimum circling altitude for different performance category IFR aircraft as defined in IAL, both day and night.
[color=purple]I think the question confused me and it was a simple cat A or B height question 400’[/color]

Once again thanks for any help!
