Do level requirements on a star constitute a clearance to descend to that level?
No
Can a STAR be reinstated once cancelled by ATC?
No
Is clearance for a STAR clearance for the approach?
No
In uncontrolled airspace, when can the instrument approach procedure for the runway not in use be used?
• Reported MET conditions indicate aircraft will comply with standard visual joining procedures
• Other IFR and VFR traffic is accounted for
When cleared for an instrument approach, how low are you cleared to descend to?
The minimum procedure commencement altitude IAW:
STAR, RNAV arrival, Route MSAs (incl. distance steps), 25nm MSA chart, TAA or VORSEC chart
When can you directly join a base turn outbound?
When within 30 degrees either side of the outbound course
When will the critical areas of the ILS be protected? (Cat 1 ILS)
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
Critical and Sensitive Area protection, Cat 2 + 3 ILS
When WX conditions below Cat 1 ILS minima:
Critical areas protected from 4nm
Sensitive areas protected from 2nm

Circling Radii: 2.66nm
Cat C Speeds and Circling Radii
Vat: 121-140
Initial approach: 160-240
Final: 115-160
Circling: 180

What wind does the procedural airspace use when designing an instrument approach?
60kts
When on a 45 degree procedure turn reversal procedure for an approach, how long much each category fly from the outbound track once turned?
A+B: one minute
C+: one minute fifteen seconds
Minimum terrain clearance on a DME arc
1000ft, 2.5nm either side of the arc
When can you intercept the DME arc from the inside?
• on a published arrival procedure
• under radar control
• VFR, or VMC until established on final approach track
When can you descend below MDA/DA?
• 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
What is a visible reference to descend below MDA/DA?
• 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
What is a visual reference to descend below MDA/DA?
• 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
Minimum assumed bank angle, missed approach
15 degrees
Minimum obstacle clearance, missed approach
98 feet at a gradient of 2.5% (150ft/NM)
Calculating Arc Distance
60 Degrees = distance of the arc
6 Degrees = distance of the arc/10
What’s the arrival segment?
The STAR
