These minima may be reduced by 100FT whenever an actual aerodrome QNH is set. Jeppesen instrument approach charts have minima for both actual aerodrome QNH and forecast aerodrome QNH. Approved sources of actual QNH are ATC and ATIS except when the aerodrome forecast QNH is provided, AWIS and Bureau of Meteorology accredited meteorological observers. An actual aerodrome QNH obtained from an approved source is valid for a period of 15 minutes from the time of receipt. Note: METAR QNH does not meet this requirement. When the actual aerodrome QNH is not available, ATC will report the Aerodrome Forecast (TAF) QNH on the ATIS. The ATIS will include information in the format “ACTUAL QNH NOT AVAILABLE, AERODROME FORECAST QNH...” Note: Forecast QNH reported by ATC or on the ATIS is not an approved source of actual QNH. Where the forecast area QNH is used, the minima used must be increased by 50FT. Aerodrome Operating Minima AIP ENR 1.5 Para 1.18 – Aerodrome Operating Minima (Jepp TERMINAL – Instrument Approach/Take-off Procedures 2.6) Landing minima are published on Australian approach charts as MDA/H or DA/H. Obstacle Clearance Altitude/Height is not published. Landing minima are the basis for determining AOM. Operators must establish AOM for each aerodrome to be used for operations. After consideration of the factors listed below, operators may determine that their AOM should be higher than the published landing minima: a) The type, performance and handling characteristics of the aeroplane. b) The composition, experience and competence of the flight crew. c) The means used to determine and report meteorological conditions. Author’s Note: the prescriptive 50 feet PEC addition no longer appears in the AIP.

For an aircraft conducting an IAP at an aerodrome: • that has an air traffic control service in operation; and • for which RVR reports are available for IAPs to the relevant runway PIC must not descend below 1,000 feet AAL where the TDZ RVR (for other than low-visibility operations) or controlling zone RVR (for low-visibility operations) is reported by ATC as continually less than the landing minima for the IAP Despite the above, the PIC may continue the IAP if already below 1,000 feet AAL when this information is received. Flying Below Lowest Safe Altitude CASR 91.305 – Minimum heights – IFR flights AIP GEN 3.3 Para 4 – Calculation of Lowest Safe Altitude (Jepp ATC – Climb and Cruise 3.6.4) “T V I V C” Take-off or landing Visual approach or departure Instrument approach or departure ATC clearance VMC by day An aircraft must not be flown under the IFR, lower than the published lowest safe altitude or the lowest safe altitude calculated in accordance with this section, unless permitted by CASR 91.265, 91.267 and 91.305 or another civil aviation legislation provision.

Descent below the straight-in MDA or continuation of the approach below the DA during APVs, may only occur when: • • • visual reference can be maintained; all elements of the meteorological minima are equal to or greater than those published for the aircraft performance category (see AIP ENR 1.5 Para 5.1.1 (Jepp TERMINAL – Instrument Approach/Take-off Procedures 7.1.1)); and the aircraft is continuously in a position from which a descent to a landing on the intended runway can be made at a normal rate of descent using normal flight manoeuvres that will allow touchdown to occur within the touchdown zone of the runway of intended landing. Page 44 of 58 NOT FOR OPERATIONAL USE | © Ben Montgomery-Schinkel 2021 | V7.0 Donate here! | Latest version at weflyplanes.com.au | facebook.com/weflyplanes | Back to top Circling Approaches and Visual Circling AIP ENR 1.5 Para 1.6.6 – Circling Approaches and Visual Circling (Jepp TERMINAL – Instrument Approach/Take-off Procedures 4.16.6) “VMC, Day Obstacle, Night MDA” Visibility along flight not less than specified for circling Maintain visual contact with landing environment Inside circling area By day not below obstacle clearance By night not below MDA until downwind, base or final Author’s note: VMC in the above mnemonic device does not mean visual meteorological conditions. During visual circling, descent below the circling MDA may only occur when the pilot: a) Maintains the aircraft within the circling area; and b) Maintains a visibility, along the intended flight path, not less than the minimum specified on the chart for the procedure; and c) Maintains visual contact with the landing runway environment (i.e., the runway threshold or approach lighting or other markings identifiable with the runway); and either • • By day: While complying with a), b) and c), maintains visual contact with obstacles along the intended flight path and an obstacle clearance not less than the minimum for the aircraft performance category until the aircraft is aligned with the landing runway; or By day and night: While from a position within the circling area on the downwind, base or final leg, complete a continuous descent from MDA to the threshold using rates of descent and manoeuvres normal to the aircraft type. Note 1: The concept is as follows: 1) The pilot maintains visual contact with the landing runway while the aircraft is circled at MDA to a position within the traffic pattern that intercepts a normal downwind, base or final approach. If the MDA is above the downwind height, the pilot maintains MDA and downwind spacing until he/she reaches a position from which descent at normal approach rates to join base can be made (see Figure 1). 2) When daylight exists and obstacles can be seen, the pilot has the option of descending from MDA from any position within the circling area while Page 45 of 58 NOT FOR OPERATIONAL USE | © Ben Montgomery-Schinkel 2021 | V7.0 Donate here! | Latest version at weflyplanes.com.au | facebook.com/weflyplanes | Back to top maintaining an obstacle clearance not less than that required for the aircraft performance category. 3) Once the pilot initiates descent below circling MDA, the obstacle protection offered by visual circling at the MDA ends and he/she is responsible for ensuring the required clearance from obstacles is maintained visually. Note 2: The pilot should maintain the maximum practical obstacle clearance. Author’s Note: altogether, circling approaches should be avoided when safer alternatives exist (such as runway-aligned approaches). Furthermore, descent to minimum obstacle clearance during visual circling should be avoided wherever possible. AIP ENR 1.5 Para 1.6.2 – Restrictions on Visual Circling (Jepp TERMINAL – Instrument Approach/Take-off Procedures 4.16.2) Visual circling is prohibited in ‘no circling’ sectors by day in less than VMC and at night. After initial visual contact, the basic assumption is that the runway environment (i.e. the runway threshold or approach lighting aids or other markings identifiable with the runway) will be kept in sight while at the MDA for circling (Reference: ICAO Doc 8168 [Jepp ATC 200 series]). The visual circling procedure conducted at or above the circling MDA will provide protection from obstacles within the circling area (see Note 1 (3) and Note 3). The information provided by spot heights on IAL charts must be treated with caution. Spot heights on IAL charts do not necessarily indicate the highest terrain, or all obstacles in the circling area. In addition, the charts may not cover all of the circling area. Before commencing an instrument approach, pilots should familiarise themselves with the location and altitude of obstacles in the circling area by studying an appropriate topographic map.

If the check indicates an unexplained discrepancy, the ILS/GLS approach should be discontinued. Pilots must conform to the following flight tolerances: a. To ensure obstacle clearance, both LOC/GLS final approach course and glideslope should be maintained within half scale deflection (or equivalent on expanded scale). b. If, at any time during the approach after the FAP, the LOC/GLS final approach course or glideslope indicates full scale deflection a missed approach should be commenced. DME or GNSS Arrivals - General AIP ENR 1.5 Para 11 – DME or GNSS Arrival Procedures (Jepp TERMINAL – DME/GNSS Arrival Procedures) The DME or GNSS Arrival Procedure is an instrument approach procedure that provides descent guidance along a specified track or sector, to the visual circling area of an aerodrome. Azimuth guidance is required from the specified radio navigation aid. The requirements of subsections 1.6, 1.9 and 1.13 apply. Descent is not permitted until the aircraft is established within the appropriate sector or on the specified inbound track. If manoeuvring within a sector is required, the pilot must ensure that the aircraft is contained within the sector, at or above the appropriate segment minimum safe altitude. Manoeuvring within a sector after passing the final approach fix is prohibited. DME or GNSS Arrivals – Operations in Controlled Airspace AIP ENR 1.5 Para 11 – DME or GNSS Arrival Procedures (Jepp TERMINAL – DME/GNSS Arrival Procedures) The clearance “CLEARED DME (or GNSS) ARRIVAL” constitutes a clearance for final approach and authorises an aircraft to descend to the minimum altitude specified in the appropriate DME or GNSS Arrival procedure. ATC is not permitted to impose any altitude restriction on such a clearance. When cleared for a DME or GNSS Arrival in controlled airspace an aircraft must not orbit, enter a holding pattern, or use holding pattern entry procedures. ATC will not issue a clearance for a DME or GNSS arrival that involves the use of a holding pattern entry procedure. Page 49 of 58 NOT FOR OPERATIONAL USE | © Ben Montgomery-Schinkel 2021 | V7.0 Donate here! | Latest version at weflyplanes.com.au | facebook.com/weflyplanes | Back to top When ATC cannot issue a clearance for an unrestricted DME or GNSS arrival, the phrase “DESCEND TO (level) NOT BELOW DME (or GNSS) STEPS” may be used. Such an instruction authorises descent in accordance with the DME or GNSS steps only to the specified altitude. ATC may clear an aircraft to intercept the final approach segment of another instrument approach procedure. When clearing an aircraft for such a procedure, ATC will use the phrase “DESCEND TO (level) NOT BELOW DME (or GNSS) STEPS” and will issue further instructions prior to the aircraft’s reaching the cleared level. Nothing in these procedures absolves the pilot in command from their responsibilities to maintain the aircraft on the authorised track or within the defined sector. Note 1: Where the track being flown is not aligned with the landing runway, a clearance for a DME or GNSS Arrival includes a clearance to manoeuvre within the circling area to position the aircraft on final for landing. Note 2: Where possible, DME and GNSS arrival procedures are designed to contain the aircraft within controlled airspace and provide 500FT separation from the CTA lower limit. However, there are locations where the procedure commences in Class G airspace, or which can take aircraft into Class G airspace on descent. Pilots should check procedures to ensure that aircraft are contained in CTA where required.

If the aircraft cannot clear obstacles on runway track, the aircraft may turn. In the event that an aircraft is unable, or does not wish, to land from an instrument approach in VMC, the aircraft must carry out the published instrument missed approach procedure for the instrument approach being flown, unless ATC directs otherwise. At Class D aerodromes with parallel runways where contra-rotating circuit operations are in progress, if ATC instructs, or a pilot initiates a go around, the pilot must: a) commence climb to circuit altitude; b) position the aircraft on the active side and parallel to the nominated duty runway, while maintaining separation from other aircraft; and c) follow ATC instructions or re-enter the circuit from upwind Author’s Note: if any doubt exists as to which procedure should be used in the event of a go around or missed approach, clarification should be sought from ATC. An example when confusion could occur would be if given the clearance, “cleared visual approach runway 01, track via the ILS”.
