Most of these flights involved curved, descending flight paths with automatic landings and final approaches as short as 0.44 n. mi. Possible uses to solve noise abatement problems with MLS equipment of varying degrees of complexity are discussed. It is concluded that altitude derived from MLS is superior to other sources near the airport traffic pattern. 收起
