An aircraft wants to fly from Europe to USA via Nat HLA track D, entry point PIKIL, and the track is a PBCS track with reduced lateral separation. Which of the following statements is correct?
  • A
    The aircraft must meet increased RVSM separation, in addition to increased navigation accuracy.
  • B

    The commander must consider that the aircraft will be more affected by wake turbulence of the preceding aircraft, since they fly closer to each other.

  • C

    The aircraft must meet additional requirements on CPDLC and ADS-C, particularly regarding the time of response to any requests.

  • D
    The aircraft must have the required PBN for the route being flown, and have 3 working LRNS for redundancy.

Performance Based Communications and Surveillance (PBCS)
PBCS (Performance-Based Communication and Surveillance) routes are implemented in the North Atlantic High-Level Airspace (NAT HLA) with the goal of improving operational efficiency, safety, and minimizing communication errors. In order to utilize PBCS routes, aircraft must adhere to specific performance criteria related to communication and surveillance. More specifically, compliance with ADS-C (Automatic Dependent Surveillance - Contract) and CPDLC (Controller Pilot Data Link Communications) is mandatory.

Aircrew must report any failure or malfunction of GNSS, ADS-C, or CPDLC equipment to ATC as soon as it becomes apparent.
