General Information
One thing to note is that the Nanchang CJ-6 makes extensive use of pneumatics to control the gear and flap extension/retraction, operate the brakes and start the engine. An engine-driven air pump recharges the system, however if air pressure is too low to start the engine then the onboard air tank can be recharged by an external source. If an external source is not available then the engine can be started by hand swinging the propeller.

Famous quotes containing the words general and/or information:
“Private property is held sacred in all good governments, and particularly in our own. Yet shall the fear of invading it prevent a general from marching his army over a cornfield or burning a house which protects the enemy? A thousand other instances might be cited to show that laws must sometimes be silent when necessity speaks.”
—Andrew Jackson (1767–1845)
“So while it is true that children are exposed to more information and a greater variety of experiences than were children of the past, it does not follow that they automatically become more sophisticated. We always know much more than we understand, and with the torrent of information to which young people are exposed, the gap between knowing and understanding, between experience and learning, has become even greater than it was in the past.”
—David Elkind (20th century)
