British PM David Cameron’s statement about Bloody Sunday

« There is no doubt, there is nothing equivocal, there are no ambiguities. What happened on Bloody Sunday was both unjustified and unjustifiable. It was wrong. » said the Prime Minister of the United Kingdom and Northern Ireland in the House of Commons this afternoon.

Also, he added:

« I know that some people wonder whether, nearly 40 years on from an event, if a prime minister needs to issue an apology.

For someone of my generation, Bloody Sunday and the early 1970s are something we feel we have learnt about rather than lived through. But what happened should never, ever have happened. The families of those who died should not have had to live with the pain and the hurt of that day and with a lifetime of loss.

Some members of our armed forces acted wrongly. The government is ultimately responsible for the conduct of the armed forces and for that, on behalf of the government, indeed, on behalf of our country, I am deeply sorry.  »

Longitudinal control systems control pitch about the lateral axis of the aircraft. Many aircraft use a conventional elevator system for this purpose. However, aircraft that operate in the higher speed ranges usually have a movable horizontal stabilizer. Both types of systems are discussed in the following text.

ELEVATOR CONTROL SYSTEM – A typical conventional elevator control system is operated by the control stick in the cockpit, and is hydraulically powered by the elevator power mechanism. The operation of the elevator control system is initiated when the control stick is moved fore or aft. When the stick is moved, it actuates the control cables that move the elevator control bell crank. The bell crank transmits the movement to the power mechanism through the control linkage. In turn, the power mechanism actuates a push-pull tube, which deflects the elevators up or down. If the hydraulic system fails, the cylinder can be disconnected. In this condition the controls work manually through the linkage of the mechanism to actuate the elevators.

HORIZONTAL STABILIZER CONTROL SYSTEM – Horizontal stabilizer control systems are given a variety of names by the various aircraft manufacturers. Some aircraft systems are defined as a unit horizontal tail (UHT) control systems, while others are labeled the stabilator control system. Regardless of the name, these systems function to control the aircraft pitch about its lateral axis.
