A same day service is currently available only to applicants requesting RVSM, NAT-HLA or PBCS approvals using the CA4040 form. This service is not guaranteed to be accepted and will be subject to workload capacity, technical involvement required and prioritisation as determined by the CAA.

These services are primarily designed to support operators with accelerated turnaround timescales in situations of urgent operational needs due to unforeseen circumstances.
