Half Moon Bay Airport (HAF) neighbors are extremely sensitive to aircraft noise. A particular annoyance is touch-and-go operations—especially when a single aircraft performs more than five (5) in a row—to those living adjacent to the airport. Airport staff request that pilots limit the number of touch-and-go operations at HAF to five (5) or fewer per flight. Adhere to these traffic pattern hours - Weekdays: Do not perform touch-and-go or full stop taxi-back operations earlier than 8:00 a.m. or later than two (2) hours after sunset. - Weekends & Holidays: Do not perform touch-and-go or full stop taxi-back operations earlier than 9:30 a.m. or later than 6:00 p.m. - Pattern work, especially touch-and-go's, is discouraged at night and on weekend and holiday mornings. - No stop-and-go operations or intersection takeoffs. - Avoid flying over the hospital located just north of the airport. - Avoid flying over homes whenever possible. - Aircraft over 12,500 lbs. prohibited.
