PCA

I forgot what this abbreviation means exactly, so can anybody help me with this?

But the idea of this system is very simple and will be used both in military and civil aviation very soon (F22 will be the first to use it). All the new airplanes of today are totally controlled by computers or also dubbed fly by wire. Once there’s a malfunction within this computer, the chanches of crashing are much higher than a technical, mechanical problem (PIO pilot oscilation, when the pilot and the computer are not reacting simultaneously). The pilot could eject ofcourse but than he loses his very expensive jet and airliners don’t have that luxury, so this is a completely new system to land this aircraft safely.

In 1989 a B737 which had to make an emergeny landing only used its throttles to land, very difficult for the pilot and not so precise. But one invented a new system controlled by software which made it very easy to land with the throttles only, so the manual control pitch was not necessairy anymore! The system was tested on a Nasa F-15 and proved to be very interresting for the future. All new aircrafts will incoporate this new PCA-system.

Will this also work for one-engined aicrafts like the F-16 or the Gripen. The F-16 is already a very unstable aicraft (manouvrability was more important), but thanks to fly by wire, the computer stabilised the aircraft. Though a malfunction of the system could envolve into a crash. Will the PCA system also work on this aircraft?
