Where is the rat on an A320?

The RAT MAN ON pushbutton (located on the “EMER ELRC PWR” section of the overhead panel on the A320) will deploy the RAT manually.

Do airplanes have backup hydraulics?

According to fearofflyinghelp.com, “aircraft have separate and redundant hydraulic systems to power flight controls, flaps, gear, thrust reversers, brakes, spoilers, etc. Each engine has a hydraulic pump and there is also an electric powered hydraulic pump. Some airplanes utilize a wind driven backup hydraulic pump.”

Where is the outflow valve located A320?

The outflow valve is below the ditching water line. Pressing the ditching button (Figure 4, “Pressurisation controls” (4)) closes the outflow valve unless it is under manual control. Note that use of the ditching button and low pressure ground air will cause a build up of differential pressure.

How does A320 PTU work?

The PTU is a reversible motor pump located between the green and yellow hydraulic systems. It enables the green system to pressurize the yellow system and vice versa. The PTU is automatically activated when the differential pressure between the green and yellow systems is greater than 500 PSI.

What is Airbus Rat system?

Description. A Ram Air Turbine (RAT) is a small turbine that is installed in an aircraft and used as an alternate or emergency hydraulic or electrical power source. The RAT generates power from the airstream based on the speed of the aircraft and is connected to an electrical generator or to a hydraulic pump.

What does rat mean in aviation?

ram air turbine
Our ram air turbine (RAT) is at the heart of an aircraft’s emergency power system.

Do planes have backup systems?

Modern airplanes are equipped with backup after backup of safety features to allow planes to land even after both engines and the electrical systems fail. The steps that follow your plane losing power are, yes, terrifying, but you’ll likely land in one piece.

Do planes have backup landing gear?

All aircraft have backup gear systems as well. The A330 has two independent control systems, alternated in use each time the gear is activated. The Boeing 747 has four separate hydraulic systems, for example. On the A330 this is achieved by retracting the shock absorbers in the landing gear strut.

How are planes pressurized?

How airplanes are pressurized. All airplane cabins are pressurized to simulate the amount of pressure felt at 8,000 feet. Pressurization happens via the engines, which compress incoming air, heat it up, and then divert some of that hot compressed air to the cabin.

What is pack in a320?

Pack flow is air flow through the air conditioning packs. There are two packs, one operated by each engine. Normally the system works on two packs, with some portion of the cabin air filtered and recirculated. The entire system can operate one one pack, which then must set to HIGH.

Where is a PTU located?

The “transfer case” that is used in FWD vehicles is called a power transfer unit (PTU), which is attached to the transaxle and sends power to a rear differential.

What is the configuration of the PTU?

The simplest and most common PTU configuration in use on aircraft today consists of two fixed-displacement rotating groups that rotate in only one direction, thus transferring power in only one direction.
