Q

What is the process for applying lateral separation?

A
  1. determine navigation (tracking) tolerances of each aircraft
  2. find the Area of Conflict (i.e. where the tolerances overlap)
  3. apply the 1 NM buffer to the Area of Conflict
  4. determine the BLSP (i.e. the point along the width of the AOC + 1NM which is closest to the aircraft track symbol)
  5. determine which method/buffer to use to establish the aircraft outside the BLSP

Q

MATS 10.4.5.1

Establish entry and exit points by one of the following:
1. applying …. to the estimate for a BLSP
2. applying ….
3. applying …. and …. corrections to a BLSP
4. passage over a …. located on the …. of a BLSP from the area of conflict
5. passage over a …. located on the …. of a BLSP from the area of conflict

A

time buffers
area navigation tolerances
slant range, DME equipment error

Q

Explain 5 in 5 out

A

If the first aircraft to exit the AOC does so at least 10 minutes before the second aircraft’s entry estimate, neither aircraft will be within the AOC at the same time, and 5 in/5 out exists.

This takes into account the +/- 5 minute time buffer to each aircraft’s estimate for entry or exit. Lateral separation exists if the estimate for the first aircraft’s exit point is the same or earlier than the estimate for the second aircraft’s entry point. (MATS 10.4.5.2.1)

Q

True or False
Z aircraft cannot be issued distance restrictions
