Glendale Airport Commissioner Carl Povilaitis agreed in principal with the committee's action because the airport needs to move forward.
"We made this commitment a long time ago," Povilaitis said. "It's not an easy process. In fact it's a difficult process because we are going into unchartered waters but we owe it to the people to who we've made the commitment."
The airport has a voluntary curfew in place for commercial aircraft between 10 p.m. and 7 a.m. A mandatory curfew would be for the same hours and would apply to all aircraft using the airport.
The airport began the study process to get a nighttime curfew approved by the Federal Aviation Administration in 2000. But assembling the study came to a halt for two reasons.
In May 2004, the FAA sent a letter to the airport stating the curfew would not be approved because it did not agree with the methodology used to show benefits of a curfew would outweigh the costs.
At the same time, the airport embarked on negotiations with the city to work out a development agreement that was adopted by both parties in January.
"There was not a lot of work done [on the study] during that particular time period," Gill said.
The process to complete the study should take about a year as the airport has to update data, revise its cost benefit analysis and look at environmental affects of the curfew, Gill said.
In November, the commission had floated the idea of getting a legislative change to the methods used in the study so as to be more favorable to the airport.
The Burbank City Council, however, indicated to the commission its preference to complete the required study.
