Does 737 Max have Eicas?
Rejected improvements. During the development of the MAX, some systems that could have improved situation awareness related to the accidents did not make it. FAA exempted Boeing from installing an Engine Indicating and Crew Alerting System (EICAS).
How does an electro hydraulic actuator work?
Electro-hydraulic actuators operate a piston with pressurized oil. A motorized pump sends fluid from a reservoir through a control valve(s) to opposite sides of a cylinder. Electric actuators utilize an electric motor and gear reduction to produce a force or torque.
What is the purpose of using actuator in a hydraulic system?
The function of the actuator in hydraulic control systems is to convert the hydraulic energy supplied by the pump and processed by the control elements into useful work.
Is the 737 MAX the same as the 737 NG?
No. 737 MAX hydraulic power is the same as 737 NG hydraulic power. There are pumps in the engines and wheel well. More info can be found here. http://www.b737.org.uk/hydraulics.htm
Is the spoiler on a 737 electrically actuated?
$\\begingroup$Electrically commanded servo valves but powered by conventional hydraulic systems with high pressure lines running throughout the aircraft, is what I understand from the article. This is not the same as electrically actuated. The 737 family uses a common type rating, spoiler actuation is a 50 year old, proven design.
What kind of actuation system does Boeing use?
Recently with the Airbus A380 and A350 XWB, these aircraft use an electrically powered actuation system for the thrust reverser, commonly referred to an E-TRAS. These systems operate similarly to the Boeing hydraulic system and mostly contain the same or similar components.
Where are the flight controls located on a 737?
This will give limited changes to the vertical flight path from the spoilers to assist the approach and landing if the normal elevator system jams. The control panel is located on the Aft Overhead Panel, even if it is switched on it will only be active when the flaps are 1 or greater.
