• Electro Hydraulic Fully Reversible • Fluid Used – MIL-H-5606 – Red in color • Normal Operations – Hydraulic – Electrical • Emergency Operations • Caution and Warning Systems

• Why is Vlr Different then Vle? • What is the purpose of the Snubber Orifice? • What is the purpose of the orifice on the nose wheel? • What does the 020 Diameter Bleed Hole Do? • Why do we have to slow to 87 to manually extend the gear? • How would you trouble shoot gear that failed to extend? Retract? • When does the gear horn go off? • Why doesn’t the nose wheel bind when you move the rudders with the gear retracted? • What turns off the hydraulic pump? Extension? Retraction?

• Flight at higher altitudes – favorable winds, better aircraft economy (ram recovery with turbine aircraft) • Regulatory Requirements – 91 and 121 • Emergency Systems – failure of aircraft structure or pressurization systems

• 91. 211 – 12, 500 – 14, 000, 15, 000 • Pressurized Aircraft – Above 25, 000 10 min supply for all passengers • Above FL 350 One crew member must wear or have a system able to supply O 2 while wearing if cabin altitude exceeds 14, 000 feet. , or if both pilots at controls and both have quick don type masks and below FL 410. • If one pilot leaves then the other must put on the mask.

• 121. 333 – 120 min rule – 10 min descent from cruise and 110 min of cruise at 10, 000 • 10 min supply for 10% of the passengers • 15 min supply for cabin attendants wherever they are when the decompression occurs.

• Continuous flow – Usable up to FL 250 or FL 180 with nasal canula. • Dilluter Demand – Good up to FL 350 • Pressure Demand – Up to FL 410 • Theories of operation

• Dalton’s Law – Partial Pressure’s of Oxygen • Law of Gaseous Diffusion and how respiration works • With a low partial pressure of oxygen in the cabin with each breath we take in even breathing 100% oxygen we can rob our bodies of O 2 due to a greater pressure differential • Pressure breathing allows higher partial pressure in the lungs and the O 2 to pass through the alveolar membrane

• High Pressure Bottles – 1800 -1850 PSI • Low Pressure Bottles – 400 -450 PSI • LOX • Chemical Oxygen Generators • Oxygen Generating Systems

• Graham’s Law – As temperature increases the pressure increases • Leaving tanks out in the sun the could quickly become empty • Hoses crack after exposure to extremes of temperature • Use of petroleum based products is not recommended due to extremely flammable nature in pure O 2 Environment.
