"Aviation authorities shall verify that the review of the aircraft control system related to flight controllability
has been adequately addressed by the manufacturer before the release of the aircraft to operations," the report says.
Accordingly, the current study assessed whether a proactive coping style indirectly predicts lower threat appraisals of organization entry, higher challenge and controllability
appraisals, and better mental health through FOC competence.
However, the level of their controllability
is drastically decreasing.
The minimal effort joysticks offer enhanced controllability
and smoothness of working functions.
With deeper understanding of the controllability
of complex networks [18-26], more scholars have begun to explore the ability to control complex networks through various indicators.
One of the most commonly applied qualitative control problems is null controllability
. The system (1) is said to be null controllable if there exists an admissible control u(t) which steers an arbitrary state [x.sub.0] of the system into 0.
and observability are two fundamental concepts in the mathematical control theory.
These retain the look of the original, and are British-made, but feature added controllability
and energy saving options.
of each system is calculated, which allows us to show that the proposed control technique preserves the locally complete state controllability
of the nonlinear controlled systems.
For the analytical approaches, the modal controllability
index has been developed by the authors in  to find suitable location of TCSC for dampening interarea model of oscillations.
The MP or UMP methods can also be regarded as a state-space method via observability or controllability
