The document discusses Aeronautical English II practice number 9. It asks the reader to summarize in their own words what ATA 29 covers and provide examples. ATA 29 refers to the hydraulic system of an aircraft, which uses pressurized fluid to operate key systems like flight controls, landing gear, doors and brakes. It provides examples of systems that use hydraulics like flight control surfaces, landing gear, cargo doors and thrust reversers. The hydraulic pipes in aircraft are typically color-coded green, blue and yellow.

Aeronautical English II PRACTICE No.

1. Tell in your own words, what the ATA 29 talks about and give some examples. (Don’t write jus
the name of the ATA)

The ATA 29 talks about the hydraulic system that the aircraft has, this system is quite
fundamental since they supply hydraulic energy through a fluid to operate the main
machinery of the aircraft or even other mechanical components, for example: flight
control surfaces, train landing gear, cargo compartment doors, and brakes also help
activate the thrust reversers. The pipes of this system in an aircraft are identified by the
colors green, blue and yellow. The hydraulic system works on the principle of Pascal's law
which says that the pressure in an enclosed fluid is uniform in all the directions.
