Pilot can maintain visual ref to terrain
Or
Ceiling is at or above the approved aprch level
Or

Q

For successive visual aprch

Q

An a/c can descend below MSA when

A

The aerodrome and terrain are visible and will remain so

A/c is being radar vectored

A/c are flying a published procedure

20
Q

Examples of non precession aprch

A 
VOR 
NDB 
Circling radar 
G/s is out 
SRA
21
Q

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

A

The ops manual

22
Q

MDA/MDH + MApt

A

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

23
Q

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

A

Set by the operator

24
Q

OCH/OCA is set by

A

Set by the state

DH/DA MDH/A can never be below this

25
Q

Limits to inst aprch

A

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

26
Q

Straight in non precession aprch

A

FAT converges with the r/y HDG of 30* or less

Established on an NDB

5* either side of the FAT

27
Q

Most accurate fixes

A

Track and bearing = ILS loc

Overhead posn = NDB

28
Q

STAR starts and ends and max intercept

A

Begins at the end of the route and ends at the IAF

Max intercept IAF to IF = 90* precession

Non precession = 120*max

29
Q

5 segments of instrument aprch

A 
Arrival 
Initial aprch 
Intermediate aprch 
Final aprch 
Missed aprch
30
Q

Arrival segment

A

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)

31
Q

Initial aprch segment

A

From IAF to IF

Max intercept angle = 90 for P or 120 for n/p

MOC = 300m

32
Q

Intermediate aprch segment

A

IF to FAF

Change speed/config

MOC = 300m to 150m

33
Q

Distance FAF from threshold

A

Optimum = 5nms

Max = 10NM

34
Q

Final aprch segment

A

FAF to MApt or l/d

R/y alignment and final descent

Min alt/height - DH/A precession MDH/A n/p

35
Q

3 phases of the missed aprch

A

Initial
Intermediate
Final

36
Q

Initial phase of m/a

A

No turns

MApt to climb established

37
Q

Intermediate phase

A

Turns up to 15*

2.5% gradient which ensures 30m MOC at all times

Climb is established to 50m MOC and can be maintained

38
Q

Final phase

A

Turns over 15* permitted

50m MOC and can be maintained to a/c initiating a new aprch/hold or returns to enroute

39
Q

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

A

6m

Wing span = 60m

40
Q

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

A

7m

Wingspan = 65m

41
Q

Calc OBH/A and MDH/A

A

Find nearest obstacle and add

90m without FAF

75m with FAF

42
Q

OCH can not be less than

A

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

43
Q

2 types of procedure turns and times

A

45/180 = cat A,B = 1 min cat C,D,E = 1.15min

80/260 = start of turn defined by fix or maybe timed

44
Q

MApt can be defined from

A

Nav facility
Fix
Specified from the FAF

45
Q

Min vis for a VM(c) aprch

A 
Cat A 1nm
B 1.5
C 2
D 2.5
E 3.5
