Why daylight matters
Flight rules for helicopters differ by day and night, and many sites and landing places operate by day only. London Heliport's normal hours run 07:30 to 19:30 on weekdays and 08:00 to 18:00 at weekends, with no flights between 23:00 and 07:00 except emergencies. Check the sunrise and sunset above against the hours of any site you plan to use.
