Alto Aviation, a supplier of business jet cabin audio systems, is urging completion and refurbishment centers to rethink speaker grille construction.

“It is one of the most common problems we encounter,” according to the Leominster, Mass.-based company. “Sound waves are made up of the compression and expansion of air [and] if air can’t move through the speaker grille, then the sound can’t get into the cabin.”

Alto recommends speaker coverings that are at least 50-percent open to ensure the best audio performance.

Duncan Aviation is authorized to modify the Universal Avionics UNS-1C flight management system to include an extended-life battery. A Duncan Aviation tech rep told AIN, “The original battery voltage was 3.6 volts and the new one is 3.93 volts. While the voltage increase in this lithium watch-type battery seems small, it makes a big difference. Previously a battery warning meant a day or two at most until you had a databus failure locking up the entire system. The new battery gives you about three months [after a warning],” he said.
