  1. During level flight, if the pilot needs to use an alternate source of static pressure vented inside the aircraft, which of the following could the they expect?
    1. an increase in airspeed and indicated altitude
    2. vertical speed will show a momentary descent
    3. a decrease in airspeed and indicated altitude
    4. an increase in airspeed and decrease in altitude
  2. During the conduct of a circling approach, what is the maximum distance in nm from the runway a CAT B aeroplane can manoeuvre?
    1. 1.66
    2. 2.68
    3. 2.66
    4. 1.68
  3. What is the minimum obstacle clearance when descending below the minimum descent altitude (MDA) in a CAT B aircraft during a daytime circling approach?
    1. 400 feet
    2. 500 feet
    3. you cannot descend below the MDA unless you are commencing descent to land
    4. 300 feet
  4. When manoeuvring your aircraft to align with the runway centreline during a day circling approach, which condition is NOT applicable?
    1. remaining within the circling area
    2. remaining at or above the circling MDA
    3. maintaining visual reference
    4. continuously in sight of ground or water
  5. An MDA for a circling approach is referenced to?
    1. aerodrome elevation
    2. threshold elevation
    3. mean sea level
    4. aerodrome reference point
  6. An IFR aircraft cleared for an instrument approach to a Class D aerodrome with
    active ATC, after becoming visual, has a clearance limit of?

    1. the nominated runway
    2. 500 feet above the runway threshold
    3. 1 nm from the threshold
    4. the circling area
  7. For an IFR flight operating in VMC, ATC authorisation for a VFR climb or descent applies in which airspace?
    1. Class C only
    2. Class D only
    3. Class D and E airspace only
    4. any class of airspace
  8. The pilot of an IFR flight departing an aerodrome with active ATC may request a VFR departure under what conditions?
    1. from any controlled aerodrome with the expectation to receive an IFR clearance enroute
    2. from a Class C aerodrome with the expectation to receive an IFR clearance enroute
    3. only when departing for cruise in Class E airspace
    4. from a Class D aerodrome with the expectation to receive an IFR clearance enroute
  9. An unpressurised IFR flight in Class E airspace, tracking 090 M at 9,000 feet, is experiencing turbulence, and the cloud tops are 100 feet higher than the aircraft. A VFR on‑top clearance is requested. What level must be maintained?
    1. any altitude that keeps the aircraft clear of cloud below 10,000 feet
    2. 9,500 feet
    3. any VFR level that complies with the VMC requirement of 1,000 feet vertically clear of cloud that is accepted by ATC
    4. 10,000 feet
  10. Can an IFR flight request a VFR on-top clearance between layers of cloud?
    1. yes
    2. no
  11. Why are stop bars installed at major airports?
    1. they improve low visibility operations
    2. they require no special equipment in the aircraft
    3. they require the pilot or driver to stop and hold at a lit stop bar
    4. all of the above
  12. Can you enter a runway from a taxiway after ATC has instructed you to line up if the stop bars are still illuminated?
    1. yes, as you have been cleared to enter
    2. no, you cannot enter and must immediately query the instruction with ATC
    3. yes, provided you visually confirm the runway and its approach area are clear
    4. yes, you can cross the stop bar and enter the runway
  13. Can you cross an illuminated stop bar to enter a runway?
    1. no, not under any circumstances
    2. yes, provided you are cleared by ATC to enter the runway
    3. yes, provided ATC have authorised you to cross the stop bar with the phrase, ‘at (holding point), cross the illuminated stop bar, runway (number)’
    4. yes, only if your clearance requires no back tracking on the runway to position for take-off
  14. Stop bars installed at major airports are a series of unidirectional red lights embedded in the pavement and are located where?
    1. At right angles to the taxiway centreline, at the associated runway holding position
    2. at the side of the runway indicating 300 m to the runway end.
    3. the taxiway edge, at the associated CAT II/III holding point, illuminated only during low visibility operations
    4. at right angles to the taxiway centreline, at the associated GLS protection area, illuminated only during low visibility operations
  15. When does the private IFR (PIFR) rating authorise a user to act as pilot in command?
    1. single pilot under the IFR anytime in any aircraft
    2. single pilot under the IFR by day and night in any single-pilot aircraft
    3. single pilot under the IFR by day only in any aircraft
    4. single pilot under the IFR by day in a single-pilot aircraft not greater than 5,700 kg MTOW

  1. A good thought provoking quiz for IFR pilots of all levels. However, the answer format (references not answers) is counterproductive. While an IR student may have ‘the books’ already open on his/ her desk, more experienced pilots may not have the time to refer to the AIPs or consult study notes. ie. boot PC, download latest AIP version, laboriously search references for answers.
    Please in future include the actual answer + reference.
