Question 7

Do level requirements on a star constitute a clearance to descend to that level?

Answer 7

No

Question 8

Can a STAR be reinstated once cancelled by ATC?

Answer 8

No

Question 9

Is clearance for a STAR clearance for the approach?

Answer 9

No

Question 10

In uncontrolled airspace, when can the instrument approach procedure for the runway not in use be used?

Answer 10

• Reported MET conditions indicate aircraft will comply with standard visual joining procedures
• Other IFR and VFR traffic is accounted for

Question 11

When cleared for an instrument approach, how low are you cleared to descend to?

Answer 11

The minimum procedure commencement altitude IAW:

STAR, RNAV arrival, Route MSAs (incl. distance steps), 25nm MSA chart, TAA or VORSEC chart

Question 12

When can you directly join a base turn outbound?

Answer 12

When within 30 degrees either side of the outbound course

Question 13

When will the critical areas of the ILS be protected? (Cat 1 ILS)

Answer 13

WX at or below 1200ft and/or 5km vis, but equal or better than Cat 1 ILS:
From 4nm from touchdown until aircraft has landed

Question 14

Critical and Sensitive Area protection, Cat 2 + 3 ILS

Answer 14

When WX conditions below Cat 1 ILS minima:
Critical areas protected from 4nm
Sensitive areas protected from 2nm

Answer 17

60kts

Question 18

When on a 45 degree procedure turn reversal procedure for an approach, how long much each category fly from the outbound track once turned?

Answer 18

A+B: one minute
C+: one minute fifteen seconds

Question 19

Minimum terrain clearance on a DME arc

Answer 19

1000ft, 2.5nm either side of the arc

Question 20

When can you intercept the DME arc from the inside?

Answer 20

• on a published arrival procedure
• under radar control
• VFR, or VMC until established on final approach track

Question 21

When can you descend below MDA/DA?

Answer 21

• the aircraft is continuously in a position from which a descent to landing can be made on the touchdown zone using normal descent rates and manoeuvres
• the aircraft can be maintained in the circling area (if applicable)
• flight visibility is not less than minima
• a visual reference to the runway is distinctly visible

Question 22

What is a visible reference to descend below MDA/DA?

Answer 22

• approach lighting system
• threshold markings
• threshold lights
• runway-end identification lights
• visual approach slope indicator
• touchdown zone or touchdown markings
• touchdown zone lights
• runway or runway markings
• runway lights

Question 23

What is a visual reference to descend below MDA/DA?

Answer 23

• approach lighting system
• threshold markings
• threshold lights
• runway-end identification lights
• visual approach slope indicator
• touchdown zone or touchdown zone markings
• touchdown zone lights
• runway or runway markings
• runway lights

Question 24

Minimum assumed bank angle, missed approach

Answer 24

15 degrees

Question 25

Minimum obstacle clearance, missed approach

Answer 25

98 feet at a gradient of 2.5% (150ft/NM)

Question 26

Calculating Arc Distance

Answer 26

60 Degrees = distance of the arc
6 Degrees = distance of the arc/10

Question 27
