EASA Annex VII (Part-NCO)

EASA Easy Access Part-NCO knowledge required for CPL (A)/IR/ME licence

During flight preparation for PBN operations, what’s the maximum duration of predicted continuous loss of fault detection that can be ignored?

With RAIM: the availability should be checked during preflight planning and in case of a predicted continuous loss of fault detection of > 5 minutes, the flight planning should be revised to reflect the lack of full PBN capability for that period.

For RNP 4 with only GNSS sensors: the maximum allowable time for which FDE capability is projected to be unavailable on any one event is 25 minutes.

For RNAV 10 operations: time limit declared for the inertial system.

Can an expired database be used for a flight?

Yes, but only if the following conditions are satisfied:

• parts of the database to be used are not changed in the current version;

• relevant NOTAMs are taken into account;

• maps and charts have not been amended;

• any MEL limitations are observed;

• database has expired by no more than 28 days.

What conditions must a pilot report when encountered or observed?

(1) severe turbulence;

(2) severe icing;

(3) severe mountain wave;

(4) thunderstorms, with or without hail, that are obscured, embedded, widespread or in squall lines;

(5) heavy dust storm or heavy sandstorm;

(6) volcanic ash cloud; and

(7) unusual and/or increasing volcanic activity or a volcanic eruption.

Other meteorological conditions that may affect the safety or efficicency of other a/c operations. (e.g. wind shear)

Define the MEL.

The Minimum Equipment List (MEL) is a document that lists the equipment that may be temporarily inoperative, subject to certain conditions, at the commencement of flight.

The items requiring an Operational or Maintenance procedure to ensure an acceptable level of safety should be identified by (O) and/or (M) in the remarks column.

Note: every external (non-structural) item that may be damaged or missing is included in the Configuration Deviation List (CDL) and NOT in the MEL.

State the tolerance of a serviceable altimeter.

± 60 ft

RVR or VIS for IAPs.

The RVR (or for non-instrument runways, VIS) for straight-in instrument approach operations should not be less than the greatest of the following:

(1) the minimum RVR (or for non-instrument runways, VIS) for the type of runway used;

(2) the minimum RVR determined according to the MDH or DH and class of lighting facility;

(3) the minimum RVR according to the visual and non-visual aids and on-board equipment used.

Note: For Category A and B aeroplanes, if the RVR determined in accordance with (a) is greater than 1 500 m, then 1 500 m should be used.

What are the visual aids for an IAP?

The visual aids, if available, may comprise standard runway day markings, runway edge lights, threshold lights, runway end lights and approach lights.

What are aircraft categories based on?

Aircraft categories are based on the indicated airspeed at threshold (V_AT), which is equal to:

• 1.3 V_S0

• 1.23 V_S1g

If both VSO and VS1g are available, the higher resulting V_AT should be used.

Aircraft categories corresponding to V_AT values.

A Less than 91 kt

B from 91 to 120 kt

C from 121 to 140 kt

D from 141 to 165 kt

E from 166 to 210 kt

Lowest possible DH/MDH based on IAP type (system minima).

ILS: 200 ft

LPV: 200 ft

VOR/DME: 250 ft

LNAV/VNAV: 250 ft

LOC: 250 ft

VOR: 300 ft

LCTR: 350 ft

Runway type minima (PA, NPA, Non-Instrument), lowest DH/MDH.

PA: 200 ft

NPA: 250 ft

Non-instrument: Circling minima

Note: Only to be used when the Obstacle Limitation Surface (OLS) used to calculate the OCH is unknown.

What is the MDH for circling operations?

The MDH for a circling approach operation with aeroplanes shall not be lower than the highest of:

(1) the published circling OCH for the aeroplane category;

(2) the minimum circling height derived from table (based on a/c category); or

(3) the DH/MDH of the preceding IAP.

Circling minima for class A

MDH: 400 ft

VIS: 1500 m

Circling minima for class B

MDH: 500 ft

VIS: 1500 m

Circling minima for class C

MDH: 600 ft

VIS: 2400 m

Circling minima for class D

VIS: 3600 m
