Facility if the complete hydraulic 15 00:00:25,350 --> 00:00:27,800 Facility if the complete hydraulic system on an aircraft fails the PCA 16 00:00:27,800 --> 00:00:27,810 system on an aircraft fails the PCA 17 00:00:27,810 --> 00:00:30,410 system on an aircraft fails the PCA software takes over providing enough 18 00:00:30,410 --> 00:00:30,420 software takes over providing enough 19 00:00:30,420

00:00:46,220 --> 00:00:46,230 software works the propulsion controlled 31 00:00:46,230 --> 00:00:49,670 software works the propulsion controlled aircraft or PCA system uses a mixture of 32 00:00:49,670 --> 00:00:49,680 aircraft or PCA system uses a mixture of 33 00:00:49,680 --> 00:00:52,340 aircraft or PCA system uses a mixture of common sensor signals and the pilots 34 00:00:52,340 --> 00:00:52,350 common sensor signals and the pilots 35 00:00:52,350 --> 00:00:54,319 common sensor signals and the pilots pitch and roll commands to adjust the 36 00:00:54,319 --> 00:00:54,329 pitch and roll commands to adjust the 37 00:00:54,329 --> 00:00:58,180 pitch and roll commands to adjust the throttles and keep the plane on course 38 00:00:58,180 --> 00:00:58,190 throttles and keep the plane on course 39 00:00:58,190 --> 00:01:01,340 throttles and keep the plane on course the software generates collective or 40 00:01:01,340 --> 00:01:01,350 the software generates collective or 41 00:01:01,350 --> 00:01:03,640 the software generates collective or equal throttle commands for the engines 42 00:01:03,640 --> 00:01:03,650 equal throttle commands for the engines 43 00:01:03,650 -->

without this PCA system throttle only control is virtually impossible on an 46 00:01:09,230 --> 00:01:09,240 control is virtually impossible on an 47 00:01:09,240 --> 00:01:12,230 control is virtually impossible on an aircraft here the pilot is trying to 48 00:01:12,230 --> 00:01:12,240 aircraft here the pilot is trying to 49 00:01:12,240 --> 00:01:14,359 aircraft here the pilot is trying to maintain a steady approach by manually 50 00:01:14,359 --> 00:01:14,369 maintain a steady approach by manually 51 00:01:14,369 --> 00:01:16,910 maintain a steady approach by manually controlling the throttles now with the 52 00:01:16,910 --> 00:01:16,920 controlling the throttles now with the 53 00:01:16,920 --> 00:01:19,850 controlling the throttles now with the PCA system on the aircraft is steadied 54 00:01:19,850 --> 00:01:19,860 PCA system on the aircraft is steadied 55 00:01:19,860 --> 00:01:21,770 PCA system on the aircraft is steadied and is actually taken to a safe 56 00:01:21,770
