The purpose that concerts hydraulic pressure into linear motion is called:
an actuator or jack
Pascale's law states that:
pressure in an enclosed container is transmitted equally and undiminished to all parts of the container and acts at right angles to the enclosing walls
Which aileron you use when?
at low speed: inbound and outbound spoilers => When the flaps are retracted (eingezogen) => only inbound ailerons => abound produces excessive moments at high speed = large enough to cause possible structural damage
When are teh outbound ailerons typically used?
outbound only use when the flaps are extended
Advantage of fly by wire
direct and indirect weight saving through simplification of systems and + Improvement of piloting quality throughout the flight envelope
In a typical hydraulic system, the overheat decetors are usually installed:
at the pumps
Overcentre mechanisms in landing gear systems are used to:
lock the landing gear in the up and/or down positions
In some aircraft, there is a protection device to avoid the landing gear being inadvertently retracted on the groud. it consists of:
a latch (Klinke) located in the landing gear lever
Unusuable fuel is:
sometimes minimized by the incorporation of tank sump pads !!!!
Given a conventional transport aeroplane with irreversible flight contols on the ground with engines running. Which of these statements about rudder trim actuation is correct?
The rudder moves, the rudder pedals move in the corresponding direction
The systems used for emergency extension of landing systems may comprise of:
compressed nitrogen, auxiliary hydraulic system and free-fall (Gravity)
Landing gear: Wo wird die Wheel speed gemessen?
am Main Gear und nicht am Nose gear
Landing gear: Welche Räder bremsen?
Bugfahrwerk bremst nicht, Centergear beim a340-200 und 300 auch nicht => Nur beim A340 600 und main gear bremsen noch
Landing gear: Carbon Brakes => Hitze beim Bremsen?
Erhitzen sich schnell und kühlen sich jedoch wieder schnell an
Landing gear:wie lässt man das Gear im Notfalll raus?
1. Umdrehung: Alle Valves auf Return => Hydraulik kann raus
2. Umdrehung: Doors werden geöffnet
3. Umdrehung: Hock geöffnet => Gear fällt raus
Landing gear: Was ist das Plyrating
Plyrating = Tire strength => Wie gut der Pneu noch ist
Landing gear: WIe hoch ist der Reibungskoeffizient bei Aquaplaning?
Er ist = 0
Flight Control: Was macht die Rudder Travel Limiting Unit?
Schaut, dass das Ruder bei hoher Speed nicht zu fest ausschlägt
