Dual control theory is a branch of control theory that deals with the control of systems whose characteristics are initially unknown. [1] [2] It is called dual because in controlling such a system the controller's objectives are twofold: (1) Action: To control the system as well as possible based on current system knowledge
Dual control is an arrangement in which aircraft control is accessible by both the aircraft pilot and co-pilot/radar intercept officer. [1] This is mostly found on ...

In many helicopters, the throttle control is a single or dual motorcycle-style twist grip mounted on the collective control (rotation is opposite of a motorcycle throttle), while some multi-engine helicopters have power levers. In many piston engine-powered helicopters, the pilot manipulates the throttle to maintain rotor speed.
The simplest form of dual key security is a lock that requires two keys to open, with each key held by a different person. The lock can only be opened if both parties agree to do so at the same time. In 1963, Canada accepted having American W-40 nuclear warheads under dual key control on Canadian soil, to be used on the Canadian BOMARC missiles.
Controllability is an important property of a control system and plays a crucial role in many control problems, such as stabilization of unstable systems by feedback, or optimal control. Controllability and observability are dual aspects of the same problem.
Every year, celebrities try to capitalize on the holiday season by releasing festive music. Singers like Mariah Carey, Ariana Grande, and Michael Bublé managed to perfect the cheesy art form ...
The Airbus A320 family was the first airliner to feature a full glass cockpit and digital fly-by-wire flight control system. The only analogue instruments were the radio magnetic indicator, brake pressure indicator, standby altimeter and artificial horizon, the latter two being replaced by a digital integrated standby instrument system in later production models.
