Highlights Flashcards
This waveforms at the leading edge when the flight speed exceeds the speed of sound
Bow waves
What happens to the strength of metalic structure when it is heated due to highspeed condition of flight
Decrease in strength
what limits the rudder deflection?
Airspeed
Tab that deflects in the same direction as the control surface
Anti-balance tab
Value of critical mach number
Mach 0.8, the local mach number increases to1(equal to the speed of sound)
Reference point zero of z axis (fuselage datum) on airbus A320
240 milimeters above the floor beams
Vertical planes parallel to the body centerline plane
Body buttock line
Major zone 400
Powerplant (and Struts)
Type of stress which a combination of compression and tension
Bending
A duplication of certain structural members to ensure that if one member failed,the other would assume the load of the failed member.
Fail Safe
Type of Construction in which a rigid framework made up of members such as beams, struts, and bars to resist deformation by applied loads
Truss type construction
Operation of bulk cargo door
it opens inwards and it is operated manually
Skin shares the load with the stringers,the frames and with an additional clip
Semi-monocoque - frames are joined together by stringers and skin with clips.
Air is removed from the lavatories and galleys by
Extraction fan
Where does pack located?
Center wing box
Where does pack and zone controllers are located
avionics compartment/electric and electronic compartment (pack controller location)
primary components of air cycle machine
• compressor
• turbine
• fan
Ways of heating ventilated cargo compartment
• Using hot bleed air from pneumatic system
• and electrical heaters
Pneumatic left and right wing isolates
Crossfeed valve & Isolation valve
Regulates the amount of trim air that is mixed with the cold air
Zone Controller
main components of recirculation system
airfilters,
electrical recirculation fans
check valves (prevent a reverse airflow to the under floor area)
Outflow valve close in what cabin altitude
15,000 ft
Supply fresh ambient air to the mixing unit when all packs fail during flight
Emergency ram air inlet
How does ELT activates when it is attached to the aircraft
GLoad
Control of the cockpit seats (m11.07,p6)
Manually and electrically controlled
Razor power supply does need
110V AC, 60Hz
Flight crew safety harness
5 point type harness and, single point release
Components inside the cargo compartment to move the ULD’s
Power Drive Unit (PDU)
