Outside Check
Before each flight
Failure classification
1. Minor Frequent (Kaffemaschine)
2. Minor Reasonable (Oeldruck)
3. Major Remote (Verlust kritische Teile, Kabinendruck)
4. Hazardous extremely remote (schwere Notlandung
5. Catastrophic Crash
Was gibt es für spoilers
Inbound and outband spoilers
Outband spoilers Funktion?
1. Speed Sprake 2. Roll spoilers 3. Ground spoilers
Inbound spoilers Funktion?
Ground spoilers
Spoilers, Flaps and are
secondary flight controll
Signal Sensoren für Bodensensor müssen alle 3 erfüllt sein, dass die Spoilers kommen. Diese wären
1. Ground (Weight on the Gear ) 2. Wheel spin up (Räder drehen mit mind. ca. 50 Kt ) 3. Revers => Idle
2 Arten von Signalleiter
Orgate (alle Signale müssen erfüllt sein) Andgate: Mind. 1 Signal muss erfüllt sein
Significant torsion effects on a wing structure druing flight can be caused by
aileron deflection ABlenkung
What are the three elements of the fuselage structure of a large transport aeroplanes
skin, frames, stringers
The principle of fail safe design of an aircraft is based on the
reduncancy (Entlassung) of the structure or equipment
Engine fire walls
stainless steel titanium sheet
incapacitiation
Arbeitsunfähigkeit
fatalities
Todesfall
) According … the worst effect of a catastrophic failure on the flight crew could be
fatalities or incapacitiation
EASA probability per flight for failures:
Minor: 10^-3 - 10^-5 => slight increase in workload
Probable: 10^-5 - 10^-7 => Physical discomfort or a significant in cerease in workload
extremely Remote: 10^-7-10^-9 => Physical distress or excessive workload impairs ability to perform task
Extremely Improbable: grösser als 10^-9 => Fatalities or Incapacitation
The torque of an eroplane engine can be measured at the
gear boy which is located between the engine and the propeller
A composite (Verbindung/ verbinden) structural compenent consists of:
a matrix and fibres
Damage tolerance
A damage tolerant aircraft will not have a specified life. Continued operation is based on frequent inspections after careful assessment => Checks become necessary
Non Cantilever Wing or Braced
In flight: upper side Compression, lower sight: tension => Im Hangar genau das umgekehrte
=> teh loads are in part taken by bracing struts or wires
How can the wing bending moments be reduced in flight?
Aileron up float and using the fuel from the center fuselage tank while maintaining the fuel in the wing tanks for as long as possible
The prupose of sringers, used in fuselage constructions, is to:
assist the skin absorb longitudinal compressive loads
Function of a rib is:
to maintain the aerodynamic shape of the wing
shape
Gestalt, Figur
enable
berechtigen, ermächtigen, befähigen, ermöglichen oder MÖGLICH MACHEN
occur
sich ereignen, vorfallen
the pressurisation load on the skin of a fuselage is:
tension ==> Druckunterschied
Cantilever wing
the structural rigidity is provided entirely by the wing structural members, without any external support
girder
Träger
a wing spar typically consist of:
a web and girders (Träger)
WO gibt es compression und tension beim Flügel
beim Root: Compression beim Tip: Tension
Im Zwischenbereich der Cockpitscheibe hat es welches Material?
polycarbonate ( vinyl)
Fuel: Which sources of heat are used on modern aircraft for fuel heaters?
Electrical heating elements, engine lubricant oil or compressor bleed air
Fuel: During fuelling the automatic fuelling shut off valves will switch off the fuel supply system when...
The fuel has reached a predetermined volume or mass.
Fuel: What is, amongst others, a reason that many aeroplane constructors design airplanes with fuel tanks in their wings?
Varying fuel load has little effect on the centre of gravity
FueL: Integral fuel tanks are widely used, but they have one particular disadvantage over other types, which?
The fuel feed and measurement system is more complex
Fuel: A fuel booster pump, besides pumping fuel to the engine, can also be utilised to...
jettison and transfer of fuel
Fuel: The purpose of baffle check valves in fuel tanks is...
To damp out the movement of the fuel in the tank.
Hydraulic: The type of hydraulic oil used in modern hydraulic system is:
synthetic oil
Hydraulic: Hydraulic power is a function of:
System pressure and volume flow
