Max - N/A
When can you commence an IAP without entering the hold?
- In controlled airspace, ATC has cleared the aircraft for the approach;
- In any airspace, for procedures using radio navaids:
1) the reversal procedure entry requirements are satisfied; or
2) the DME arc entry requirements are satisfied; or
3) the en route track to the procedure’s commencement fix or facility is within 30° either side of the first track of the procedure. - For procedures using GNSS:
1) in any airspace, the aircraft is tracking to an initial approach waypoint from within the capture region for that waypoint; or
2) in controlled airspace, the aircraft is being vectored to intercept the initial approach segment or is tracking direct to the intermediate fix.
Note: “direct to” clearances may be requested to the intermediate fix (IF) provided that the resultant track change at the IF does not exceed 45 degrees
Reversal procedures - types and geometry
Draw them up
FIHA ENR 1.5-15 2.8.2
Direct entry limitation for entering a reversal procedure?
Within +/- 30 degrees of the outbound track
Limitations in holding patterns?
Outbound timing commencement
- Outbound timing begins abeam the fix or on attaining the outbound heading, whichever comes later.
- Time/Distance outbound. The outbound leg must be no longer than:
1) up to and including FL140 - 1MIN or the time or distance limit specified on the chart; - Turns. All turns in nil wind should be at a bank angle of 25° or Rate One, whichever requires the lesser bank.
Rated coverage of VORs below 5000ft and 5000-10 000ft?
Below 5000ft - 60nm
5000ft-10000ft - 90nm
Rated coverage or LOC at 2000ft within 10 deg of course line?
25nm
Rated coverage of LOC above and below 5000ft?
Below 5000ft - 30nm
Above 5000ft - 50nm
You receive the QNH from the ATIS, what can you do to the MDA/DA on the plate?
Reduce by 100ft for 15mins
NPID options
- Splay departure
- Circling departure
- Visual climb to conduct missed approach for departure
- Visual departure
When IF, when can you land at an aerodrome without an IAP?
Where there is no IAP, an approach can be made;
- by day
- vis > 8km
- cloud above final route segment + 500ft
NDB errors
Mountain effect - reflection of mountains
Interference - other NDBs nearby on similar frequency
Night effect - interference from sky waves
Thunderstorm interference - cumulonimbus clouds generate a lot of radio energy that can cause the ADF to fluctuate towards it
Quadrantal error - reflections off the aircraft before reaching the receiver based on the angle
Coastal effects - coastal refraction; the different conductivities of land and water cause the signal to bend
What area does RNP2 nav consider?
5nm surrounding and including the departure point, destination, and left/right of the nominal track
IFR Standard Take-off Minima SI(NA)?
- Clear of cloud until achieving the greater of Vy, Vtoss, Vmin IFR
- RVR/Visability;
A. 550m with runway edge light at not more than 60m intervals and either centreline lighting or markings
B. 800m
What emergency training is not permitted IMC?
- UA
- Emergency landing (practice forced landing)
- Flight control malfunctions
- Composite mode
- Partial panel (sole reference to standby AI)
‘Appropriate period of time’ - sector 2 entry
Flown outbound for the appropriate period of time from the holding fix, where timing is specified, up to a maximum of 1min 30sec,
Or if earlier;
The appropriate limiting DME distance
What is the standard holding pattern direction?
Right turns
How much hPa can area QNH be from accurate QNH?
+/- 5 hPa
What is an accurate QNH, and what is it used for?
Obtained from ATS, ATIS, AWIS
Used for assessing altimeter tolerances
What is an actual QNH?
QNH received from ATC, ATIS, AWIS or BoM
Valid for 15mins
What counts as a positive fix IFR?
- Passage of aircraft over an NDB, VOR, TACAN, marker beacon or DME site
- Intersection of 2 or more position lines which intersect at angles not less than 45 degrees; obtained from a combination of NDBs, VORs, TACANs, localisers within their rated coverages
- For only NDBs, must be within 30nm
What can be waived during first 3hrs of TAF3?
- 30min buffers for FM and BCMG periods (holding fuel for deteriorations)
- Alternate/holding fuel required for PROB30 or PROB40 for;
A. Reduction in vis due fog, mist, dust
B. TS or SEV TURB
RNP approach tolerances?
1nm at initial & intermediate
0.3nm in final approach
1nm in missed approach
How far from an aerodrome can you use its QNH?
100nm
SI(NA) Normal, Limited & Poor Conditions
Normal: 1000ft cloud base and 3km vis
Limited: Clear of cloud, in sight of ground or water, 800m vis, speed sufficient to avoid
- weather must allow visual recovery (‘limited conditions’) at the approach minima for a published instrument approach
Poor: Less than limited conditions
Minimum heights overwater?
Not below 50ft by day.
Not below 400ft in IMC (both day & night) or VMC night unaided. Unless:
A) conducting IMC recovery
B) reference to SGSI
Coast-out point VMC?
On the coastline
Coast out point IMC?
- 2nm off the coast by GPS
- 1nm off the coast with specified RADAR (must be painted)
Minimum STODA (Supplementary Take off Distance Available)?
800m
Minimum height at end of runway for NPID?
50ft
RA 1
Can flight plan through the RA, and expect a clearance from ATC
RA 2
Must not plan to fly through, unless on a route specified in ERSA OR under agreement from the controlling authority.
Clearance from ATC is not assured.
RA 3
Do not plan to fly through, and clearance will not be available.
Can you fly through danger area?
Approval for flight within an active danger area outside of controlled airspace is not required.
It is the pilots responsibility to be aware of the dangerous activity and take appropriate precautions.
