Frederf Posted August 17, 2016 Posted August 17, 2016 BLC or SPS is best noticed by watching the UUA-1 indicator. In the DCS version BLC switching off due to speed increasing is not implemented (or not noticeable like the flight manual says) so it cannot be seen. I notice about a 1.5 units of UUA-1 change BLC on or off. There is a loss of lift which changes the flight path without BLC. To compare equally both conditions it is necessary to adopt the same flight path as before (stick motion). If this is not done the BLC change by looking at the UUA-1 gauge is less visible. Example: 85% N1, 280kmph, landing configuration, -5m/s, BLC on angle is 15 units. Turning BLC off it is 16 units after returning to -5m/s (increase in rear stick). If I don't adjust the stick back the descent increases to -8.5m/s and the angle is unchanging. Shifting below the BLC gate on the throttle (~50% N1, also nozzle open light) is noticeable. BLC on activation seems to change true AOA by ~0.3° alpha and UUA-1 by ~0.7 units. Perhaps a better test, 330 kmph IAS stabilized in auto control mode PRMG. With BLC it is about 10° units and without BLC it's slightly more than 11° (11.3?). So it seems BLC in in effect but not as much as the manual says it should (2-2.5 units) by about 2x.
