Technology In The Cockpit

摘要

Regarding your article about fuel totalizers, we should not assume they are always precise without periodically verifying their accuracy. On every other fill-up, I write down what my Shadin indicates as the number of gallons used and compare it to the number of gallons required to fill up the tanks. I have found my totalizer indicates about two percent more fuel in the tanks than actually exist, and therefore will have to have the Shadin adjusted accordingly. On another subject-noise-cancel-rnling headsets-they have become so good that they cancel out most of the significant engine sounds of the aircraft. On takeoff, one of the most significantrn"early warning" indicators of an engine problem is "change of engine sound."
