Please define ‘standard rate turn’ (For example: How many degrees per unit of time, deg per minute?)
Answer – A “standard rate turn” is defined as a 2-minute 360deg turn, and is typically quoted as 3 deg/sec turn rate. Airspeed, bank angle, normal load factor, and turn rate are related by maneuver mechanics equations for steady, coordinated flight. Sizing to two times standard rate turn, provides some aerodynamic margin to actually performing a standard rate turn. If rotor(s) are used for primary lift in cruise, it (they) should be operating below incipient stall for this condition. There are several internet references to “standard rate turn”.
