Questions
UK CAA — asked and answered
Is UK night the same as EASA night?
No, and this is the divergence that catches people who move between the two. EASA runs night from the end of evening civil twilight; the UK Air Navigation Order prescribes thirty minutes after sunset. On the same sector the two produce different night totals — both correct, under their own rules.
Does the UK still recognise PICUS after leaving EASA?
Yes. UK retained Part-FCL keeps FCL.050 and the AMC1 FCL.050 column layout, including the pilot-function split and PICUS. The substantive divergence is the night definition, not the command model.
