By the time the pilot arrives, the airplane has already
undergone a series of checks by ANA's highly trained professional mechanics. In
the first check of the day, the mechanics turn on the power in the airplane and
check that every system is operating correctly. They check that the hydraulic
system works correctly, see that the rudder and ailerons move smoothly, and make
sure that the tires are correctly pressurized.
Preparation during the winter is particularly thorough. Snow on the airplane affects
more than just the weight of the plane -- it has a negative influence on its aerodynamic
performance. While you are waiting to board, mechanics and other ground staff
remove the snow from the aircraft. We have various methods of snow removal available
to us today. Instead of removing it by hand, a chemical de-icing agent is sprayed
on the aircraft to remove the snow. However, snow trapped in tight spots and places
that can't be reached by the spray must be removed by hand, just like in the old
days.
Summer also raises some concerns. After landing on a hot runway, a plane's tires
become extremely hot. If the tires become too hot, the air pressure in the tire
increases and air is released through the pressure release valve. That must be
kept in mind when the aircraft tires are checked. |
