Day Wataru started the test run that lowered the awning of the pane of the airport internal airplane on the 14th for air-conditioning cost and exhaust carbon dioxide (CO2)

 
reductions of the airplane.
The awning is lowered in six airports such as Haneda by the parking arrival at nighttime, and where an in-flight room temperature advance by the sunlight next morning is suppressed is examined.

Because the airplane flies by the degree of front about 50 degrees in the sky according to day Wataru, air-conditioning is unnecessary.
However, the ground should rise because of sunlight an in-flight temperature, start auxiliary power plant (APU) before it takes off at the summer time, and make air-conditioning work.

Proposer’s captain Keiji Kushino (42) is expecting, “The CO2169 kilo can be reduced with one jumbo jet if ten minutes are shortened at the operation time of APU”.
