The air pressure measuring instrument on the primary runway of the airport has been reportedly damaged due to the thunderstorms which affected the city on Wednesday morning.
This resulted in flight delays as all the calculations had to be done manually, using a portable digital barometer.
A team from AGS Ltd, which has a maintenance contract with the Indian Metrological Department (IMD) arrived from Delhi today for repairing the instrument.
The air barometer is an automated system which gauges the air pressure in the atmosphere and data is relayed periodically to the air traffic controllers and the pilot(s). The reading helps them in taking accurate decisions, especially during departure and landing. The said instruments help in determining whether an alternative runway has to be used or operation stopped for a while due to change in wind direction and pressure.
An airport official said that all measures are being taken to normalise the situation.
