Approach Procedures

Question 1

What is meant by OCA for precision approach and non precision approach

Answer 1

Precision = The lowest altitude at which a missed approach must be initiated to ensure compliance with the appropriate obstacle clearance

Obstacle clearance altitude/height

Non Precision = lowest height above aerodrome elevation below which an aircraft cannot descend without infringing obstacle clearance

Question 2

MAPt

Answer 2

Missed Approach point which must be initiated in order to ensure minimum obstacle clearance is not infringed

Electrical glide path

Question 3

Departing the pattern

Answer 3

Pilot should adjust the pattern within the limits of established holding procedures in order to leave holding point at the time specified

Question 4

FAP

Answer 4

Fixed approach point (precision) - on the final approach track where the intermediate approach altitude intercepts the nominal glide path

(Nominal Glide Path)

Question 5

Visual manoeuvre- circling

Answer 5

Describes instrument approach bringing ac in position for landing on a different runway than in instrument arrival

Question 6

Arrival Segment

Answer 6

Transition from en route to procedure via STAR

Question 7

Initial approach segment

Answer 7

Procedure between the initial approach and intermediate fix

Question 8

Intermediate approach segment

Answer 8

Between the intermediate fix and final approach fix/point

Speed and config adjusted to prepare for final

Question 9

Final approach segment

Answer 9

Segment of instrument approach which alignment and descent for landing are accomplished

Question 10

Procedure turn

Answer 10

Turn made away from designated track followed by a turn in opposite direction to permit ac to intercept and proceed along reciprocal of designated track

Question 11

Base turn

Answer 11

Not reciprocal - turn executed by ac during initial approach between the end of the outbound track and beginning of intermediate/final track

Question 12

Glide path interception generally occurs between what heights

Answer 12

1000ft and 3000ft

Question 13

Primary and secondary area

Answer 13

Primary area - 1/2 each side of the track
Secondary area - 1/4 each side of the track

Question 14

Straight approach

Answer 14

30 degrees or less deviation from centreline

Question 15

Procedure turn vs base turn

Answer 15

Procedure turn = reciprocal
Base turn = non reciprocal

Question 16

Aircraft categories based on speed at threshold are for

Answer 16

Aircraft’s manoeuvrability to the procedure for the approach

Question 17

MSA

Answer 17

Minimum sector altitude - lowest alt guaranteed minimum obstacle clearance of 1000ft - 25nm radius

Question 18

Loss of glideslope procedure

Answer 18

Either a non precision approach is used if time permits or go around

Question 19

OCA precision

Answer 19

Lowest altitude above runway for a missed approach

Question 20

Holding Patterns turn direction

Answer 20

Turns to the right

Question 21

MDA

Answer 21

Minimum Descent Altitude

Question 22

What is the radius of MSA

Answer 22

25nm

Question 23

On circling approach what should pilot keep in sight

Answer 23

Runway environment whilst at MDA/H

Question 24

ILS Accuracy providing track guidance

Answer 24

+-2.4 degrees

Question 25

ILS Accuracy Not Providing Track guidance

Answer 25

+-1.4 degrees

Question 26

VOR Accuracy providing track and not providing track

Answer 26

VOR With track = +-5.2 degrees
VOR without track = +-4.5 degrees

Question 27

NDB Accuracy with and without track guidance

Answer 27

NDB With track guidance = +-6.9 degrees
NDB without track guidance +-6.2 degrees

Question 28

What is the optimum glide path angle for an ILS approach with no obstacles

Answer 28

3 degrees
Max = 3.7 degrees/6.5% A/B
Max = 3.5/6.1% - C/D/E

Question 29

IAF to IF angle of interception for:
PA
NPA
DR

Answer 29

Precision Approach = 90 degrees
Non Precision Approach = 120 degrees
Dead Reckoning = 45 degrees

Question 30

What must ATC pass when pilot is unfamiliar with approach charts

Answer 30

The initial approach level
Final approach track

Question 31

How long must be allowed between an aircraft taking off in any direction and a straight in approaching aircraft

Answer 31

5 minutes until before the arriving aircraft is estimated to be over the instrument runway

Question 32

How long must be allowed between an aircraft taking off with a direction different by 45+ degrees from approach of arriving aircraft

Answer 32

3 minutes

Question 33

OCH difference for precision and non precision approach

Answer 33

Precision = The lowest altitude above the elevation of the threshold at which missed approach must be initiated

Non precision = lowest altitude above aerodrome elevation of aerodrome or threshold is more than 7ft below aerodrome elevation

Question 34

Expected Approach Time

Answer 34

The time at which ATC expects that an arriving aircraft following a delay will leave the holding fix to complete its approach for a landing
