Practical 400 Hz use Cases for Aviation Teams
Published by Dranetz Technologies, Inc. Below are three situations aviation teams often face, and how the HDPQ Xplorer 400 helps resolve them. Jetway keeps resetting when an aircraft connects What’s happening: During bridge movement or aircraft power-up, the 400 Hz supply dips. Sometimes it is a brief sag, other times a fast transient that trips protection.Continue reading “Practical 400 Hz use Cases for Aviation Teams”
