One pack per flight, in a fixed order: aircraft, NOTAM, weather, minima, profile, performance, fuel, mass and balance, radio failure and flight plan. Add or remove pages as you need. Prints as a booklet.
Ask about anything in your preparation: “What is the pressure altitude?”, “Is 1.25 × TODR inside TORA?”, “What fuel do I need for 1 h 40 min with a 30 min alternate?”. The instructor sees what you have filled in and reads your documents from Flight Intelligence.
