Flight bags shrink with flight time and experience.
When flying away for a holiday bag is slightly fuller but on one day flights I carry:
- headphones
- kneeboard (to jot down take off and landing times)
- pen (to jot down take off and landing times)
- chart (or piece of chart) for area overflown
- approach plate if available
- time ruler (to give estimates to ATC - don't have gps)
- licence and medical
- sunglasses
