denokan Appr да, вы правы, включается Stall Logic.
The stall detection circuit monitors the flap position and the angle of airflow.
Near stall, the speed trim function trims the stabilizer to a nose down condition to allow for trim above the stickshaker AOA and idle thrust.
The trim continues until the stabilizer gets to its limits or the aft column cutout position is exceeded.
If the roll angle from the ADIRU is more than 40 degrees, it opens an electronic switch and stops the speed trim signals.
Давайте тогда уже разделять работу sts по скорости в нормальных условиях и работу в условиях stall management. В каком контексте написано о прекращении работы sts при рассогласовании уа?
Всё раскидано по разным местам.
The air data inertial reference unit (ADIRU) sends these signals to the FCC for speed trim calculations:
• Computed airspeed (CAS)
• Mach
• Inertial vertical speed
• Roll angle
• Angle of attack
The speed trim warning circuit supplies a warning signal if any of these conditions are not present:
• Air/ground sensors valid
• Stabilizer move in 10 seconds when commanded
• Engine N1s valid
• Stab trim position sensors valid
• Data from the air data inertial reference unit (ADIRU) valid - в FCC BOV (bias out of view) LOGIC TABLE есть сверка AOA data.
• Clutch valid and trim valid signals present.
The air/ground sensors are valid if these conditions are present:
• Engines N1s are more than 18%
• Computed airspeed (CAS) is less than 80 knots
• Angle of attack (AOA) less than 15 degrees
• The squat switch shows the airplane is on the ground.
The speed trim warning circuit also supplies a warning if the FCC commands a trim up and trim down signal at the same time.
