RTO Testing
An RTO is usually seen as one of the hardest tests an airplane has to undergo for its certification trials. The RTO test is performed under the worst possible conditions; i.e. with fully worn out brakes, the plane loaded to maximum takeoff weight and no use of thrust reversers.
During an RTO test most of the kinetic energy of the airplane is converted to heat by the brakes, which may cause the fusible plugs of the tires to melt, causing them deflate; and small fires may start. This is acceptable to pass the test, as long as the resulting fire does not spread to the airplane body. The airport fire brigade will have to wait for five minutes before they are allowed to cool the brakes.

Famous quotes containing the word testing:
“Today so much rebellion is aimless and demoralizing precisely because children have no values to challenge. Teenage rebellion is a testing process in which young people try out various values in order to make them their own. But during those years of trial, error, embarrassment, a child needs family standards to fall back on, reliable habits of thought and feeling that provide security and protection.”
—Neil Kurshan (20th century)
