Question 1

What is the minimum radar separation you need between two planes that are 20 miles from the radar antenna?

Answer 1

3nm

Question 2

What is the minimum radar separation you need between two planes that are 30 miles from the radar antenna?

Answer 2

3nm

Question 3

What is the minimum radar separation you need between two planes that are 40 miles from the radar antenna?

Answer 3

5nm

Question 4

List all instances and separation minimums for wake turbulence.

Answer 4

f. Separate aircraft operating directly behind, or
directly behind and less than 1,000 feet below, or
following an aircraft conducting an instrument
approach by:
1. Heavy behind heavy− 4 miles.
2. Large/heavy behind B757− 4 miles.
3. Small behind B757− 5 miles.
4. Small/large behind heavy − 5 miles.

Over the threshold:

1. Small behind large− 4 miles.
2. Small behind B757− 5 miles.
3. Small behind heavy− 6 miles.

Question 5

Aircraft not laterally separated, may be vertically separated by what methods?

Answer 5

Assign altitudes to aircraft, provided valid
Mode C altitude information is monitored and the
applicable separation minima is maintained at all times.
Assign an altitude to an aircraft after the aircraft
previously at that altitude has been issued a climb/descent clearance and is observed (valid
Mode C), or reports leaving the altitude.

Question 6

What are the exceptions to the above vertical separation rule?

Answer 6

-an aircraft on a cruise clearance
-assign an altitude to an aircraft only after the
aircraft previously at that altitude is observed at or
passing through another altitude separated from the
first by the appropriate minima when:
1. Severe turbulence is reported.
2. Aircraft are conducting military aerial
refueling.
3. The aircraft previously at that altitude has
been issued a climb/descent at pilot’s discretion.

Question 7

What is the minimum radar separation you need between a plane and an obstruction that are 30 miles from the radar antenna?

Answer 7

3nm

Question 8

What is the minimum radar separation you need between a plane and an obstruction that are 40 miles from the radar antenna?

Answer 8

5nm

Question 9

What is the minimum radar separation you need between a plane and adjacent airspace that are 30 miles from the radar antenna?

Answer 9

1 1/2nm

Question 10

What is the minimum radar separation you need between a plane and adjacent airspace that are 40 miles from the radar antenna?

Answer 10

2 1/2nm
