Since the first test in spring 1990, aerial distribution of baits has been developed as the main bait distribution variant in the new federal states of Germany. Experiences are given in respect of organisation, management and enforcement of oral immunization campaigns and cooperation between veterinary agencies and flight enterprises. Practical aspects are described to ensure bait density, preparation of maps, creation of technical preconditions and realisation of dropping rhythm. Aerial dropping in comparison with hand distribution of baits was shown to be equivalent at least in respect of bait uptake and seroconversion rate.
