Mnemonics and Main Memory Items | Planning Minima

Question 1

The Planning Minima:

Answer 1

May only select a destination or destination alternate aerodrome if the conditions indicate that during a time of 1 hour before to 1 hour after the ETA, the conditions are at or above the applicable planning minima:

1. for destination aerodrome:

(i) RVR/Vis must be in accordance with that specified in CAR 91/07.5; and
(ii) for a non-precision approach or a circling approach, the ceiling at or above the MDH;

2. for a destination alternate aerodrome:

must in accordance to table 2-10:

Cat II and III: Cat I minima

Cat I: NPA minima and ceiling must be above the MDH

NPA: NPA minima plus 200ft added to MDH and 1000m added to RVR/Vis. Ceiling must be above MDH +. 200ft

Circling: Circling

Question 2

Additional fuel

If an operator’s fuel policy includes planning to an isolated aerodrome for which a destination alternate is not required or does not exist, the amount of fuel at departure shall include:

Answer 2

(e) additional fuel, if required, but not less than
(i) for aeroplanes with reciprocating engines, fuel to fly for 45 minutes plus 15% of the flight time planned to be spent at cruising level, or two hours, whichever is the lesser or
(ii) for aeroplanes with turbine engines, fuel to fly for two hours at normal cruise consumption after arriving overhead the destination aerodrome

(CATS 2011)

3. Aerodromes supporting a minimum of two instrument approach and landing operations to different suitable runways, at least one shall be cat II or III(ceiling and visibility):

Answer 3

1. Applicable aerodrome operating minima plus an increment of 400ft. Applicable aerodrome operating minima plus an increment of 1 500m.

Answer 4

RVR/Visibility for NIL: 500m
RVR/Visibility for Runway edge lighting/or centreline: 250/300m
RVR/Visibility for Runway edge and centreline lighting: 200/250m
RVR/Visibility for Runway edge and centreline lighting and multiple RVR information: 150/200m

NOTE: The higher values apply to Cat D

Question 5

Take-off Minima:

Circling:

(1) The lowest minima to be used by an operator for circling are:

Cat A MDH ? -

Cat B MDH ? -

Cat C MDH ? -

Cat D MDH ? -

Answer 5

Cat A MDH 400ft - 1500m

Cat B MDH 500ft - 1600m

Cat C MDH 600ft - 2400m

Cat D MDH 700ft - 3600m

Question 6

Selecting a destination alternate/planning:

We use aerodrome operating minima (in this case, our planning minima = operating minima unless aerodrome is isolated)

Ceiling is considered

Commence take off:

We use planning minima

Ceiling is considered

On an IFR flight, a commander shall not commence take-off unless the expected weather conditions at the destination and/or required alternate aerodrome(s) are at or above the planning minima, during a period from 1 hour before to 1 hour after the estimated time of arrival at the aerodrome

Airborne to continue to destination:

We use aerodrome operating minima

Ceiling is not considered

Question 7

Explain the precision approach minima for both Aeroversity and ICAO:

Answer 7

Cat I DH not lower than 200ft, visibility 800m and RVR 550. Aeroversity same

Cat II DH not lower than 100ft and RVR 300m. Aeroversity same

Cat IIIa DH lower than 100ft or no DH, RVR not lower than 175m. Aeroversity RVR 200m.

Cat IIIb DH lower than 50ft or no DH, RVR lower than 175m but not lower than 50m. Aeroversity RVR 200 - 75m.
