NEW DELHI: With a severe cyclonic storm just miles away from Maharashtra and Gujarat, the Directorate General of Civil Aviation (DGCA) has issued a list of precautions that airlines must oversee to fly safely in this adverse weather.
The “monsoon circular” has also been issued as airlines have restarted domestic flights only from last Monday after a two-month suspension of schedule operations.
“The low pressure area developing over the Arabian Sea is likely to intensify into a severe cyclonic storm and cross north Maharashtra and south Gujarat coasts in the evening/night of June 3…. In view of the COVID-19 situation, aviation related activities have been very limited… Operators and individuals have a challenge at hand in restarting flying after a prolonged period of non-flying and the associated weather at this time of the year across India,” the circular being issued to operators and pilots to reiterate some existing guidelines on adverse weather operations said.
The regulator has asked airlines to deploy more experienced crew at these times. “Runway surface condition and effect of the same on aircraft performance should be understood and taken into account. Runway condition has a direct impact on aircraft maximum allowable take off weight and decelerating capability. Fuel uplift calculation should be done very judiciously and it should take into account enroute and destination weather and trend forecast. Selection of a suitable destination alternate is also an important aspect during adverse and monsoon conditions,” it said.
Last monsoon had seen a spate of runway incursions during monsoon after which the aviation authorities had cracked down on airline and airport operators.
“The available fuel should be constantly monitored, as enroute weather avoidance and use of anti-ice devises may end up consuming more than the planned fuel for such activity. Prior to descend, diversion station and fuel for diversion should be discussed and clearly understood by the crew members, as this can create uncertainties at a later stage of the approach,” the circular read.
“Selection of appropriate auto brakes or usage of adequate manual brake (where auto brake system is not available) should be done to ensure safe stopping of the aircraft. Landing distance requirement for actual landing weight, environment and runway conditions should be calculated for every landing,” the circular added.
