Instrument Procedures And Approaches

Question 1

VFR minima in a CTR

Answer 1

Ground vis not less than 5km
Or
Cloud ceiling not less than 1,500ft

Question 2

Prior to any instrument departure

Answer 2

Must have clearance

Must have necessary plates available - if you don’t - ATC can read the departure plate inc missed aprch and loss of comms procedures

Question 3

Obstacle clearance - instrument procedures

Answer 3

Based on the highest obstacle within 5nm of track

300m

600m for mountainous regions

Question 4

Procedure design gradient

Answer 4

3.3%

Question 5

Guaranteed obstacle clearance at the end of the DER

Answer 5

0

Question 6

Straight dep

Answer 6

Initial dep track is within 15* of the alignment of the r/y

Based upon track guidance acquired within 20km from DER

Track guidance is provided by radio aids

Question 7

Turning dep

Answer 7

Dep track req a turn of more than 15* of the r/y alignment - turning area is constructed

Based upon tack guidance acquired within 10km of the DER

Straight flight is assumed until reaching 120m above DER and a MOC of 90m

Question 8

Omni directional dep

Answer 8

No track guidance req

A/c climb on extended r/y centreline - 120m before turns can be specified
At least 90m obstacle clearance will be provided before turns greater than 15*

Question 9

SIDs start and end at

Answer 9

Start at DER and end at a point joining the ATS system

Question 10

MSA on a plate

Answer 10

Depicted out to 25nm from the facility

Question 11

To fly a SID a/c have to equip with

Answer 11

2 VORs
1 ADF
1 DME

Question 12

An IFR flight can be cleared for a visual aprch if

Answer 12

Pilot can maintain visual ref to terrain
Or
Ceiling is at or above the approved aprch level
Or
Pilot reports at any time during the inst aprch that the met conditions make a visual aprch can be accomplished

Question 13

Visual aprch separation shall be provided by

Answer 13

By ATC between cleared a/c and other arriving and departing a/c

Question 14

For successive visual aprch

Answer 14

ATC will maintain separation until the pilot reports that he/she has the traffic in front in sight

Then the pilot will be instructed to maintain own separation from proceeding a/c

Question 15

Instrument aprch design is dictated by

Answer 15

Terrain surrounding the aerodrome
Type of nav aids
Airspace restrictions
Type of ops

Question 16

Most significant factor for instrument aprch

Answer 16

Speed (VAT)

Question 17

Cat A and B a/c aprch speeds

Answer 17

Cat A - Vat = <91
Initial aprch speed range = 90/150
Final aprch speed range = 70/100
Max speed for VM(f) = 100

Cat B - Vat = 91/120
Initial aprch speed range = 120/180
Final aprch speed range = 85/130
Max speed for VM(f) = 135

Question 18

Max speed for track reversal/racetrack procedures

Answer 18

Cat A = 110

Cat B = 140

Question 19

An a/c can descend below MSA when

Answer 19

The aerodrome and terrain are visible and will remain so

A/c is being radar vectored

A/c are flying a published procedure

Question 20

Examples of non precession aprch

Answer 20

VOR 
NDB 
Circling radar 
G/s is out 
SRA

Question 21

Guidance on how to calc DH/DA can be located in

Answer 21

The ops manual

Question 22

MDA/MDH + MApt

Answer 22

A/c at MDH/MDA but before MApt can fly level to MApt - if still not getting visual ref commence missed aprch

Can initiate missed aprch before MDH/MDA but must pass over MApt

Question 23

D/H D/A MDH/MDA are set by

Answer 23

Set by the operator

Question 24

OCH/OCA is set by

Answer 24

Set by the state

DH/DA MDH/A can never be below this

Question 25

Limits to inst aprch

Answer 25

Non precession- RVR no lower than 300m Precession- not past the outer marker If RVR falls below the limits after passing the above then the aprch may be cont down to DH/A for precession MDH/A for non

Question 26

Straight in non precession aprch

Answer 26

FAT converges with the r/y HDG of 30* or less Established on an NDB 5* either side of the FAT

Question 27

Most accurate fixes

Answer 27

Track and bearing = ILS loc Overhead posn = NDB

Question 28

STAR starts and ends and max intercept

Answer 28

Begins at the end of the route and ends at the IAF Max intercept IAF to IF = 90* precession Non precession = 120*max

Question 29

5 segments of instrument aprch

Answer 29

``` Arrival Initial aprch Intermediate aprch Final aprch Missed aprch ```

Question 30

Arrival segment

Answer 30

Starts on leaving the enroute phase or 25nms Ends at the IAF May be specified as a star MOC 300m Min level/alt dictated by MSA (within 25nms)

Question 31

Initial aprch segment

Answer 31

From IAF to IF Max intercept angle = 90 for P or 120 for n/p MOC = 300m

Question 32

Intermediate aprch segment

Answer 32

IF to FAF Change speed/config MOC = 300m to 150m

Question 33

Distance FAF from threshold

Answer 33

Optimum = 5nms Max = 10NM

Question 34

Final aprch segment

Answer 34

FAF to MApt or l/d R/y alignment and final descent Min alt/height - DH/A precession MDH/A n/p

Question 35

3 phases of the missed aprch

Answer 35

Initial Intermediate Final

Question 36

Initial phase of m/a

Answer 36

No turns MApt to climb established

Question 37

Intermediate phase

Answer 37

Turns up to 15* 2.5% gradient which ensures 30m MOC at all times Climb is established to 50m MOC and can be maintained

Question 38

Final phase

Answer 38

Turns over 15* permitted 50m MOC and can be maintained to a/c initiating a new aprch/hold or returns to enroute

Question 39

Vertical distance from the wheels and the GS aerial for cat A and B

Answer 39

6m Wing span = 60m

Question 40

Vertical distance from the wheels and the GS aerial for cat C and D

Answer 40

7m Wingspan = 65m

Question 41

Calc OBH/A and MDH/A

Answer 41

Find nearest obstacle and add 90m without FAF 75m with FAF

Question 42

OCH can not be less than

Answer 42

CAT A = 120m - goes up by 30m for each cat Min obstacle clearance CAT A and B = 90m CAT C and D = 120m CAT E = 150m

Question 43

2 types of procedure turns and times

Answer 43

45/180 = cat A,B = 1 min cat C,D,E = 1.15min 80/260 = start of turn defined by fix or maybe timed

Question 44

MApt can be defined from

Answer 44

Nav facility Fix Specified from the FAF

Question 45

Min vis for a VM(c) aprch

Answer 45
