As private space launches increase and diversify, those activities are causing "significant impacts" on commercial aviation, according to a white paper (PDF) published by ALPA last week. Those impacts include flight delays, flight-plan alterations, increased distance flown, longer flight times, flight cancellations, crew duty cycle changes, gate slot management and added fuel burn. As one example, ALPA said the SpaceX Falcon Heavy launch in February affected 5,000 square NM of airspace, causing 563 flight delays averaging eight minutes each, and an additional 34,841 NM flown due to diversions.
