Question regarding aircraft category groups
I was flying into Manchester England, EGCC. On our Jeppesen briefing pages 10-1P for Manchester, England there was a reference to 2 groups of aircraft that our publication (Jeppesen) referenced but I could not identify.
The reference was under nighttime restrictions 1.2.3
They were Q8 and Q16 group aircraft.
Can anyone help me understand the information? Could you also reference the publication ?
Thank you.
