ADS-33E

The ADS-33E is a rotorcraft handing quality standard. It specifies bandwidth and phase delay. For ACAH the bandwidth is defined by the 45 degree phase margin frequency. For rate response systems the bandwidth is the lesser of the 45 degree phase margin frequency or the 6 dB gain margin bandwidth.
