ATPL(A) · subject 090
The shortest subject on the syllabus, and the one where marks are lost most carelessly: almost everything turns on exact lists — an order of priority, a message sequence, a readability scale.
Written on the EASA Learning Objectives, checked against the primary texts, delivered as an A4 PDF and a screen edition, in English and in French.
