aircraft subgroups (3)
airframe, engine, systems
system groups (3)
structure, vehicle system, avionic system
flight controll system
-fly-by-wire
-input system for pilot to controll deflection of the rudders and controll the A/C
air data system
provides airspeed, altitude, air temperature, rate of climbe or descent information
essential functions
loss would reduce capability of the A/C
critical functions
loss could cause loss of hole A/C or fatal injuries
severity of a failure condition relate to its probability in which way?
Schwere des Fehlers steht in welchem Zusammenhang zu seinem wahrscheindlichen Auftreten?
inversely proportional
four probapility terms
-probable: one or more times
-remote: several times
-extremely remote: few times
-extremely improbable: not anticipated to occure
design concepts of parts in a system (3)
-Safe-Life
-Fale-Safe
-Fault-Tolerant
Safe-Life
specific designed life with no failures
Fale-Safe
will cause no harm to other parts in the system if it fails
Fault-Tolerant
a system can continue operating in event of its failure
max vertical velocity during landing for landing gear
10 ft/s (3.05 m/s)
positive and negative of a taildragger
+ lower weight
+ less drag
- unstable when rolling
- hard breaking -> A/C may tipp over on the nose
advantages of tricycle landing gear
+ better visibility for the pilot
+ more stable when rolling
+easier loading and unloading
types of shock absorbers
- spring type
- bungee type
- oleo struts
facts to consider when design a tricycle landing gear (2)
- ground pitch
- roll angle
advantages of hydraulic systems
- excellent power to weight ratio
- high reliability
- fast response
- precise position and load control
