During a turn the nose of the aircraft is continually pitching up. Your pitch gyro will see this and attempt to stop it. This results in the nose dropping, and a decrease in altitude. Your pressure sensor will sense this loss of altitude and attempt to correct it. So, effectively, the gyro and pressure sensor will be working against each other(slightly) and the end result is that your plane will not hold the desired altitude, but one slightly lower than the desired altitude. This is especially true in the early portions of the turn.  2, record 4, English, - pitch%20gyro

The propeller governor incorporates an adjustable stop, which limits the maximum speed at which the engine can run. As soon as the takeoff r.p.m. is reached, the propeller moves off the low-pitch stop. The larger propeller blade angle increases the load on the engine, thus maintaining the prescribed maximum engine speed.  3, record 5, English, - flight%20fine%20pitch%20stop

[The Allison A6441FN-606 and 606A turbopropeller has the two following features :] Mechanical Low-Pitch Stop(MLPS). The mechanical low-pitch stop is designed to prevent the inadvertent entry of the blades into the beta range during flight in the event of propeller-control-system malfunction. The MLPS with a setting of 18. 25 to 18. 5 ° "backs up" the normal hydraulic low-pitch stops. Hydraulic Low-Pitch Stop(HLPS). The hydraulic low-pitch stop is designed to prevent the propeller hydraulic governor from decreasing the blade angle into the beta range during governing operation. The HLPS has a setting of 20 ° blade angle from 30 to 68 ° coordinator. From 68 to 90 ° coordinator HLPS is scheduled from 20 to approximately 31. 5 ° blade angle. This scheduling is called beta follow-up and means that the propeller pitch cannot decrease below 20 or 30 ° during constant-speed operation controlled by the governor.  4, record 5, English, - flight%20fine%20pitch%20stop
