Solihull Council’s planning sub committee unanimously backed the project but the decision is subject to a revised 106 agreement being taken back to the planning sub committee for a full discussion.
The Secretary of State will now decide whether or not to intervene in the decision making process.
The application was to extend the runway by 405 metres and included a new air traffic control tower and the realignment of the A45 through a tunnel for motorists.
Members agreed that any 106 agreement should serve to protect local people from the effects of increased noise, restrict air traffic movements and improve public transport, ecology, air quality, employment and tourism.
Chairman of the Planning Sub Committee Stuart Davis, said: “It is vital that our residents are protected from the impact of noise and an increase in traffic, and that the local environment is not adversely affected.
"We have a duty to our residents, and by taking another look at the 106 agreement, we will be able to come to an agreement that benefits and protects all concerned.
"We feel that the expansion of the runway will have a tremendously positive impact on the local economy, bringing in over 2,100 jobs and around£113m income.”
