Q

If RVR is below limits what is the lowest you can go for non- precision and precision approaches

A

Non- precision

29
Q

What is the initial approach segment

A

Aircraft had left the en route structure and is entering the instrument approach procedure

30
Q

What is the intermediate approach segment

A

In which the aircrafts speed and configuration is adjusted to prepare the aircraft for the final approach

31
Q

In which segment is the aircrafts speed and configuration adjusted to prepare the aircraft for final approach

A

Intermediate approach segment

32
Q

What is the final approach segment

A

In which alignment and descent for landing are made

33
Q

What is missed approach segment

A

Which must be followed if the approach cannot be continued

34
Q

When does the arrival segment start and finish and what is the MOC

A

Starts on leaving en rote phase or 25nm

MOC 300m

35
Q

When does the initial approach segment start and end and what is the MOC

A

Starts at the IAF
Ends at the IF

MOC 300m

36
Q

When does the intermediate approach segment start and finish
What is the MOC

A

Starts at initial fix

Ends at the final approach fix

MOC reduces from 300m to 150m

37
Q

When does the final approach segment start and end

A

Starts final approach fix

Ends on landing or at the missed approach fix

38
Q

When does a STAR begin and end

A

Normally begins at the end of the en route

End at the initial approach fix

39
Q

What is the max intercept from IAF to IF for precision and non precision approaches

A

Precision = 90°

Non precision = 120°

40
Q

What is the max intercept for a dead reckoning between IAF to IF

A

45° at 10nm

41
Q

What is the optimum distance for a FAF

A

Final approach fix

Optimum 5nm
Maximum 10nm

42
Q

What is a step down fix

A

A point on a approach at which a certain height can’t be descended below

If reach height before it = level off until reach SDF (step down fix)

43
Q

When can a aircraft descent to MDH/ MDA on a non precision approach with no FAF

A

Once established on the final approach track (FAT)

NDB = +/- 5° of final approach track

44
Q

Who is responsible for terrain clearance

A

Pilot in command always

Except

When being radar vectored

45
Q

What is the OCH / OCA set by

A

The state

Non precision reference from aerodrome elevation or threshold if it is more than 7ft below aerodrome elevation

for VM(C) based upon the highest obstacle in the VM(c) area

A

Turn from outbound to inbound track

55
Q

What is a procedure turn

A

Turn from outbound to inbound where track is reciprocated

56
Q

What is the times for a track reversal 450/180° procedure turn

A

CAT A and B = 1 min

CAT C and D and E = 1min 15 seconds

57
Q

What is a base turn track reversal

A

Outbound on one track and inbound on a different track

58
Q

What is a approach turning point

A

Will have a DME range

Takes priority over timings

59
Q

In the missed approach where does the initial phase start and end

A

Starts at the missed approach point

Ends when climb established

No turns allowed

60
Q

In the missed approach where does the intermediate phase start and end

A

Starts at climb established
Ends at 50m obstacle clearance can be maintained and guaranteed

Turns up to 15° allowed

2.5% gradient climb endures 30m obstacle clearance at all times

61
Q

In the missed approach where does the final phase start and end

A

Starts at 50m obstacle clearance can be maintained

Ends aircraft initiates new approach, hold, or returns to en-route

Turns over 15° permitted

MOC 50m

62
Q

Can you fly over the MAPt higher than the altitude on the procedure

A

Yes as long as you pass over it

Ensure min obstacle clearance is not infringed throughout the procedure
