November Disruptions

November Disruptions at a glance

November was a month of Bird Hits where it is very difficult to find that who hits whom.

Either Bird Hits our Aeroplanes or Pilot hit Birds.But one thing is clear that company looses huge amount on this account.

Can we adopt another COLOUR SCHEME for Engine SPINNER as it is evident world wide that when spinner was coloured spirally, incident of BIRD HITS was reduced worldwide.

Another area to be meticulously followed is of water draining from FT for a/c on GND more than 2 to 3 hrs which has a role in minimising the Filter Clog warning .
