A320 technical questions Flashcards
chapter 7
how many planes in the A320 family
4 - a318,19,20,21
how often does an a320 take off or land
1.6 seconds
what are the golden rules based off of
basic flying principles
adaption of basic flying principles to modern tech aircraft
the provision of info and the required crew coordination when operating not just airbus but any commercial aircraft.
what is a further objective of the golden rules
offer guidance on flight crew interactions with complex systems and to deploy some of the fundamental principles of CRM to ensure flight efficiency and to try and help prevent incidents becoming accidents
when was a320 first introduced and flew
march 1984, 22 February 1987
how many passenger can it accommodate
150-186
powered by what engines
2 CFM or IAE engines located under the wings. LE uses CFM engines
what technology does A320 use
fly by wire
how does fly by wire work
controls the flight controls by digital inputs.
pilot controls the side stick which feeds the inputs to various flight control computer which in turn control the surfaces
what else does fly by wire offer
many flight envelope protections by preventing pilots from being able yo put the ac in configs or attitudes that are undesirable eg stall
what does the control law in use determine
the handling characteristics of the ac
what are the 4 control laws
normal alternate direct and mechanical backup
each has a varying degree of built in protections
describe the CFM jet turbine engines
high bypass ratio engines and are monitored by a full authority digital engine control (FADEC)
what is FADEC
a digital control system that performs complete engine management and monitoring
how many continuous operating hydraulic systems in the a320
3
what are the 3 colours of the hydraulic system and what does each system have
green, blue and yellow and own hydraulic reservoir
what is the normal hydraulic operating pressure
3000psi
what is the idea behind the multiple hydraulic systems
redundancy - each controlling different aspects of the ac.
If an issue arises with certain components of the yellow or green system, the other remaining system can power both to maintain serviceability via a power transfer unit (PTU)
what does the electrical system comprise of
three phase 115/400Hz constant frequency AC system and a 28V DC system
how does the ac provide power in normal operation
provides AC power from 2 engine driven generators and 1 Auxiliary power unit (APU) generator
what can each generator provide
electrical power to all the electrical bus bars
is AC power converted to DC
yes for certain functions
what happened if the normal generation of AC power is not available
a emergency back up generator that can provide some ac power to essential systems
how do the main landing gears retract
inboard
how does the nose landing gear retract
forwards
when are the landing gear doors open
only when the gear is extending and retracting
what happens if the ac loses hydraulic or electrical power for landing gear
a hand crank allows the flight crew to extend the landing gear via gravity
what are the two types of autopilot and flight director modes
managed modes and selected modes
managed modes
steers the ac along the lateral, vertical and speed profiles.
according to the data the pilot inserts into the multi functional control display unit (MCDU).
flight management (in the flight management and guidance computer) computes the corresponding guidance targets
selected modes
steers the ac according to the target values the pilot selects and the FCU display

where does the flight mode annunciator (FMA) appear
top of the PFD, across 5 columns and 3 lines
what does a change to the flight control unit (FCU) prompt
change in the FMA on the PFD

what is the airbus dark cockpit concept
concept for the overhead panel (OHP) makes it simple and quick to identify faults or failures
if ac is fully serviceable then OHP does not have any white lights illuminated
how is the OHP laid out
cascade system panel arrangement making for a logical flow that helps minimise error when selecting systems and managing failures
how are system panels labelled on the OHP
in white on the top or side of the panel for ease of finding the correct system and switch/indication/ push button (p/b)
