GM1 SERA.8005(b) Operation of air traffic control service

Q: What is the basis for issuing a clearance to a pilot to maintain own separation in airspace Classes D and E below 10,000 ft during climb or descent?

The clearance is based on the fact that in those airspace classes a speed restriction of 250 kt is applied to all flights, allowing pilots of both aircraft to observe other flights in time to avoid collision.

Q: Under what specific conditions may a pilot be cleared to maintain own separation in airspace Classes D and E below 3,050 m?

A pilot may be cleared to maintain own separation in airspace Classes D and E below 3,050 m (10,000 ft) during climb or descent, during day in visual meteorological conditions.

Q: Why is the 250 kt speed restriction relevant to clearances for pilots to maintain own separation in Class D and E airspace below 10,000 ft?

The 250 kt speed restriction is relevant because it allows pilots of both aircraft to observe other flights in time to avoid collision, which is the basis for such clearances.

Q: In which airspace classes and altitude range does the rule allow a pilot to maintain own separation during climb or descent, and what weather and time-of-day conditions must apply?

The rule allows a pilot to maintain own separation in airspace Classes D and E below 3,050 m (10,000 ft) during climb or descent, during day in visual meteorological conditions.

Q: What is the rationale behind permitting own-separation clearances in Class D and E airspace below 10,000 ft, according to the guidance material?

The rationale is that in those airspace classes a speed restriction of 250 kt is applied to all flights, allowing pilots of both aircraft to observe other flights in time to avoid collision.

CLEARANCES TO MAINTAIN OWN SEPARATION

Clearances for a pilot to maintain own separation in respect of a specific portion of the flight in airspace Classes D and E below 3 050 m (10 000 ft) during climb or descent, during day in visual meteorological conditions are based on the fact that in those airspace classes a speed restriction of 250 kt is applied to all flights, allowing pilots of both aircraft to observe other flights in time to avoid collision.
