1. Refer to the YTMU RNAV-S Approach. You have joined the approach at TMUSA in a Category B aircraft. Other aircraft on the CTAF have indicated that the wind is blowing from the north but that the visibility is below VMC. What is the lowest altitude you can descend to on this approach?

  1. 2030 AMSL
  2. 2080 AMSL
  3. 2130 AMSL
  4. 2180 AMSL

2. You are operating IFR in class G airspace and not identified. You receive a RAIM warning. You should:

  1. operate in DR mode and notify ATS after one minute
  2. notify ATS immediately and land as soon as possible
  3. navigate visually or by reference to ground based aids until RAIM is restored
  4. advise ATS within 5 minutes of RAIM loss

3. To avoid a thunderstorm, you divert from your track at point A by 20 degrees and travel for 20nm to point B. As an alternative to using GRID LSALT, what area should be considered to calculate your LSALT at position B?

  1. a 10 nm radius around B
  2. a 9 nm radius around B
  3. 5 nm surrounding 15° splays either side of the line from A to B and then a 10 nm radius around B
  4. 5 nm either side of the line from A to B and then a 5 nm radius around B

4. You are planning a flight to Merimbula (YMER) in winter. Using the TAF information:

TAF YMER 072321Z 0800/0900

RMK T 22 24 25 20 Q 1013 1010 1008 1009
Which of the following ETAs is possible without any operational requirements?

  1. 080015
  2. 081000
  3. 080115
  4. 081100

5. You are operating in controlled airspace in IMC near Canberra and receive a RAIM warning. After three minutes, ATC requests your distance from the CB VOR. Your reply should be:

  1. 26 GNSS CB VOR DEAD RECKONING MODE
  2. distance not available, ETA CB 0546 
  3. 26 GNSS CB VOR NEGATIVE RAIM
  4. 26 DME CB

6. Planning a flight from Walgett (YWLG) to Bathurst (YBTH), you are concerned about freezing levels. Which route selection would give you the lowest LSALTs for your trip? 

  1. AGETA H202 MUDGI W 575 BTH
  2. AGETA 822 DU W 540 BTH 
  3. YWLG DCT YBTH
  4. AGETA W 822 ONUMA W717 BTH

7. You file a flight plan as follows: YSDU – DU – YPKS – CWR – YCWR. What is the lowest route segment LSALT for the trip? 

  1. 4000
  2. 4100
  3. 6100
  4. 3900

8. What is a suitable method for checking an IFR altimeter is within limits prior to take-off? 

  1. set TAF QNH and check that altimeter reads within limits
  2. set published field elevation on the primary altimeter
  3. on the runway threshold and with AWIS QNH, check against AD chart data
  4. at the holding point with ATIS QNH, check altimeter readings against ARP elevation

9. The item G in section 10 of a flight plan notification requires what entries at section 18?

  1. NAV/RNP2; PBN/O2S1
  2. NAV/GNSS; PBN/RNP APCH
  3. NAV/RNP2; PBN/RNP APCH
  4. NAV/GNSS; PBN/O2S1

10. On a flight to Canberra (YSCB) in IMC you have been cleared to track direct CB on W137 at 5000 clearance limit 15 nm CB. At 17 nm CB you are instructed to turn right heading 240°. You then suffer a radio failure. What are your initial actions?

  1. squawk 7600, maintain 5000 and hold at 15 nm CB for three minutes
  2. squawk 7600, climb to 5900, maintain heading 240° for two minutes
  3. squawk 7600, maintain 5000 and immediately fly one complete holding pattern
  4. squawk 7600, descend to maintain VMC and track direct to the field. 

11. What is the definition of the circling area and minimum obstacle clearance for a category C aircraft positioned 3 nm abeam the approach threshold?

  1. 1.68 nm / 400 ft 
  2. 2.66 nm / 400 ft
  3. 4.20 nm / 400 ft
  4. 5.28 nm / 400 ft

12. You have a flight planned from YSWG to YSCB at 9000 via W 148. At 40nm CB in IMC you encounter icing. To what level can you descend? 

  1. 5900
  2. 6100
  3. 6500
  4. 6200
