Lateral Seperation

Question 1

The distance between those portion of the intended route for which a/c are to be laterally separated is

Answer 1

never less than an established distance to account for navigational inaccuracies plus a specified buffer

Question 2

Who set the buffer?

Answer 2

The appropriate authority

Question 3

In different geographical locations as determined by position reports to:

Answer 3

• visual observation
• use of nav aids
• use of RNAV equipment

Question 4

What should happen if the equipment fails?

Answer 4

Provide alternative separation methods or minima

Question 5

Means by which lateral separation may be applied including the following

Answer 5

• reference same or different geographical locations
• use of nav aids
• different nav aids or methods
• RNAV ops where RNP is specified on parallel tracks
• transition into airspace where a greater lateral separations applies

Question 6

What is a geographical separation?

Answer 6

Separation positively indicates by position reports over different geographical locations as determined visually or by reference to a navigational aid

Question 7

Track Separation between a/c using the same nav aid/method. Requiring a/c to fly in specified tracks which are separated by a minimum amount appropriate to nav aids or method employed. There are 4 methods list them.

Answer 7

• VOR
• NDB
• GNSS/GNSS
• VOR/GNSS

Question 8

Define VOR separation

Answer 8

Both aircraft are established on radials diverging by at least 15 degrees and at least one aircraft is at a distance of 15nm or more from the facility

Question 9

Define NDB separation

Answer 9

Both a/c are established on tracks to or from the NDB are diverging by at least 30 degrees and at least one a/c at a distance of 15nm or more from the facility.

Question 10

Lateral separation between a/c using different navigation aids, or when one a/c is using RNAV equipment, shall be established by ensuring that the derived protected airspace’s for the navigation aids or RNP do not overlap.

True or False?

Answer 10

True.
