What is lateral separation?
Separation between diverging tracks
What is the separation minima for a lateral VOR?
Tracks diverging 15 degrees and one aircraft reporting 15 NM
What is the separation minima for a lateral NDB?
Tracks diverging 30 degrees and one aircraft reporting 15 NM
What is longitudinal separation?
Separation between two aircraft on the same, crossing or reciprocal (opposing) tracks
What is same track?
Angular difference less than 45 degrees or more than 315 degrees
What is reciprocal (opposing) track
Angular difference more than 135 degrees or less than 225 degrees
What is crossing track?
Angular difference from 45 to 135 degrees and 225 to 315 degrees
What are the two types of horizontal and longitudinal separation?
Separation based on time or on distance
What are the 4 time separations for Same Track and Same Level?
15 minutes if no NAVAIDs available, 10 minutes if NAVAIDs permit, 5 minutes if preceeding aircraft is 20KT faster or 3 minutes if preceeding aircraft is 40 KT faster
What are the 3 time separations for Same Track - Climb or Descent?
15 minutes if no NAVAIDs available, 10 minutes if NAVAIDs permit, 5 minutes if level change is commenced within 10 minutes after succeeding aircraft has passed a common point derived by NAVAIDs
What is the time separation for Reciprocal (opposing) Track - Climb or Descent?
10 minutes before and after estimated time of passing
What are the time separations for Crossing Track - Same Level?
15 minutes if no NAVAIDs available, 10 minutes if NAVAIDs permit
What are the distance separations for Same Track - Same Level?
20 NM or 10 NM if preceeding aircraft has a TAS of at least 20 kts faster
What is the distance separation for Same Track - Level Change?
10 NM between aircraft changing level and aircraft maintaining
What are the distance separations for Crossing Track - Same Level?
20 NM or 10 NM if preceeding aircraft has a TAS of at least 20 kts faster
What is the distance separation for Reciprocal (opposing) Track - Climb or Descent?
10 NM
