ICAO 8168: PANS-OPS Flashcards
Minimum obstacle clearance is divided in to … parts called … and …
2
primary volume (close to track where full obstacle clearance is guaranteed)
secondary volume (outside the primary where decreasing obstacle clearance is provided)
Width of obstacle clearance volume increases with what distance?
Increases with increasing distance from runway
Fix tolerance for terminal area radar (TAR) within …NM is +/- …km (…NM)
20NM
1.5 KM (0.8 NM)
Fix tolerance for en-route surveillance radar (RSR) within 40NM is +/- …km (…NM)
+/- 3.1km (1.7NM)
DME fix tolerance is …NM + …% of distance from antenna
- 25NM
- 25%

Max angle of interception of initial approach segment for;
a) a precision approach
b) a non-precisionn approach
a = 90 degrees
b = 120 degrees
What is a procedure turn?
What are the two types?
a manoeuvre in which a turn is made away from a designated track followed by a turn in the opposite direction to permit the aircraft to intercept and proceed along the reciprocal of the designated track
Two types are the 45/180 and 80/260 procedure turns
What is a base turn?
consists of a specified outbound track and timing or DME distance from the facility, followed by a turn to intercept the inbound track where the tracks are not reciprocal
Obstacle clearance reduces to … during the intermediate approach segment
500ft
For a straight in approach, the angle formed by the final approach track and the runway centreline must not exceed? (two categories)
30 degrees for procedures restriceted to CAT A and B only
15 degrees for other categories
The final approach fix should not be more than … from the landing surface

On an ILS or MLS approach, the final approach segment begins at the … and ends at the …
final approach point (not fix)
