Airport bosses have appealed against a decision not to allow an increase in flights from a Hampshire airfield.
Airport bosses want to see weekend flights doubled
TAG Aviation wants to double the number of weekend take-offs and landings at Farnborough Airport.
A four-day public inquiry has begun, after plans were rejected last year by Rushmoor District Council when thousands of residents objected.
The company had said it hoped to increase employment in the area and would restrict ground noise.
It wants to increase the number of permitted take-offs and landings at the airport at weekends and on bank holidays from 2,500 a year to 5,000 a year.
The Planning Inspectorate is this week reviewing the decision, and has invited public responses to the scheme.
The airport's new £10.2m terminal opened last May.
