What does MCAS do? | When does MCAS activate? | WHAT UPDATES BOEING MADE IN B737MAX?|SINGHURS |

Описание: The Boeing 737 max is a reengineering from the 737NG. The 737 max fitted with CFM International LEAP-1B engines and, To get the engine under the 737 wing, designers needed to place the engine nacelle higher and also more ahead on the plane, the layout results a higher pitching activity when it is traveling at slow speeds and as will result in stalls.

MCAS stands for maneuvering characteristics augmentation system, the MCAS is specifically created software for the 737 max it helps the airplane itself. MCAS is activated without pilot input and also only runs in manual, flaps up flight, the MCAS computes the Jets airspeed turns the straight stabilizer in the tail of the aircraft up and after that instantly trims nose down and enabling the aircraft to be level, this prevents the aircraft from stall.

Boeing presents new flight control software maneuvering characteristics augmentation system( MCAS) so that the 737 max would certainly have the taking care of high qualities needed by regulators. MCAS counted on info from a solitary sensor to check the angle of the aircraft.

When does MCAS activate?
MCAS was made to trigger just when all 3 of the list below problems occur at the same time:
The pilot is flying the plane manually.
The airplane nose approaches a higher-than-usual angle.
The pilot has the wing flaps up.

Exactly how did MCAS initially function?
Prior to being improved, MCAS relied upon information from a solitary Angle of Strike (AOA) sensing unit to monitor the angle of the airplane. In both accidents, a single AOA sensor offered wrong details to MCAS, which created it to trigger. In both instances, MCAS involved repeatedly when the sensing unit continued to improperly report a high AOA.

In both mishaps (Lion Air and Ethiopian airline) the sensor provided incorrect details to MCAS.The incorrect data created MCAS to activate repeatedly.The actions taken by Boeing and regulatory authorities have been through.These updates added redundancy as well as safety safeguards.
