Flight Procedures - General

Question 1

Name the definition:

A specified altitude or height in the precision approach or approach with vertical guidance at which a missed approach must be initiated if the required visual reference to continue the approach has not been established.

It comes in two forms - height and altitude. Each are referenced above what datums?

Answer 1

Decision Height/Altitude

Height is referenced to threshold elevation

Altitude is referenced above mean sea level.

Question 2

Name the definition:

A fix established in a precision approach at the FAP to eliminate certain obstacles before the FAP, which would otherwise have to be considered for obstacle clearance purposes.

Answer 2

Descent fix

Question 3

Name the definition:

That segment of an instrument approach procedure in which alignment and descent for landing are accomplished.

Answer 3

Final Approach Segment (FAS)

Question 4

A predetermined manoeuvre which keeps an aircraft within a specified airspace while awaiting further clearance.

Answer 4

Holding procedure

Question 5

A fix that marks the beginning of the initial segment and the end of the arrival segment, if applicable. In RNAV applications this fix is normally defined by a fly-by waypoint.

Answer 5

Initial Approach Fix(IAF)

Question 6

That segment of an instrument approach procedure between the initial approach fix and the intermediate fix or, where applicable, the final approach fix or point.

Answer 6

Initial Approach Segment

Question 7

That segment of an instrument approach procedure between either the intermediate fix and the final approach fix or point, or between the end of a reversal, racetrack or dead reckoning track procedure and the final approach fix or point, as appropriate.

Answer 7

Intermediate Approach Segment

Question 8

A fix that marks the end of an initial segment and the beginning of the intermediate segment. In RNAV applications this fix is normally defined by a fly-by waypoint.

Answer 8

Intermediate Fix(IF)

Question 9

A specified altitude or height in a non- precision approach or circling approach below which descent must not be made without the required visual reference.

It comes in two forms - height and altitude. Each are referenced above what datums?

Answer 9

Minimum Descent Altitude/Height

Height is referenced to aerodrome elevation or to threshold elevation if it is more than 2m below the aerodrome elevation.

Altitude is referenced to mean sea level.

Question 10

The altitude for an en-route segment that provides adequate reception of relevant navigation facilities and ATS communications, complies with the airspace structure and provides the required obstacle clearance.

Answer 10

Minimum en-route altitude(MEA).

Question 11

The minimum altitude for a defined segment that provides the required obstacle clearance.

Answer 11

Minimum Obstacle Clearance Altitude(MOCA)

Question 12

The lowest altitude which may be used which will provide a minimum clearance of 300m(1000ft) above all objects located in an area contained within a sector of a circle of 46km(25nm) radius centred on a radio aid to navigation.

Note: This definition differs from the South African version - 1500ft

Answer 12

Minimum Sector Altitude

Question 13

That point in an instrument approach procedure at or before which the prescribed missed approach procedure must be initiated in order to ensure that the minimum obstacle clearance is not infringed.

Answer 13

Missed Approach Point(MAPt)

Question 14

The procedure to be followed if the approach cannot be continued.

Answer 14

Missed Approach Procedure

Question 15

The lowest altitude or the lowest height above the elevation of the relevant runway threshold or the aerodrome elevation as applicable, used in establishing compliance with appropriate obstacle clearance criteria.

Note 1.— Obstacle clearance altitude is referenced to mean sea level and obstacle clearance height is referenced to the threshold elevation or in the case of non-precision approaches to the aerodrome elevation or the threshold elevation if that is more than 2 m (7 ft) below the aerodrome elevation. An obstacle clearance height for a circling approach is referenced to the aerodrome elevation.

Answer 15

OCA/H

Question 16

A manoeuvre in which a turn is made away from a designated track followed by a turn in the opposite direction to permit the aircraft to intercept and proceed along the reciprocal of the designated track.

Answer 16

Procedure Turn

Question 17

A procedure designed to enable the aircraft to reduce altitude during the initial approach segment and/or establish the aircraft inbound when the entry into a reversal procedure is not practical.

Answer 17

Racecourse Procedure

Question 18

The height of the extended glide path or a nominal vertical path at the runway threshold

Answer 18

Reference Datum Height

Question 19

A statement of the navigation performance necessary for operation within a defined airspace.

Answer 19

Required Navigation Performance(RNP)

Question 20

A procedure designed to enable aircraft to reverse direction during the initial approach segment of an instrument approach procedure. The sequence may include procedure turns or base turns.

Answer 20

Reversal Procedure

Question 21

A designated instrument flight rule (IFR) arrival route linking a significant point, normally on an ATS route, with a point from which a published instrument approach procedure can be commenced.

Answer 21

Standard Instrument Arrival(STAR)

Question 22

A designated instrument flight rule (IFR) departure route linking the aerodrome or a specified runway of the aerodrome with a specified significant point, normally on a designated ATS route, at which the en-route phase of a flight commences.

Answer 22

Standard Instrument Departure(SID)

Question 23

Terminal Arrival Altitude(TAA)

The lowest altitude that will provide a minimum clearance of ___ m (______ ft) above all objects located in an arc of a circle defined by a __ km (__ NM) radius centred on the ____ ________ fix (IAF), or where there is no IAF on the intermediate fix (IF), delimited by straight lines joining the extremity of the arc to the IF. The combined TAAs associated with an approach procedure shall account for an area of 360 degrees around the IF.

Answer 23

Terminal Arrival Altitude(TAA)

The lowest altitude that will provide a minimum clearance of 300 m (1 000 ft) above all objects located in an arc of a circle defined by a 46 km (25 NM) radius centred on the initial approach fix (IAF), or where there is no IAF on the intermediate fix (IF), delimited by straight lines joining the extremity of the arc to the IF. The combined TAAs associated with an approach procedure shall account for an area of 360 degrees around the IF.
