three years from the date the aircraft/component was released

What stands "SMS" for within the context of aviation?

Safety Management System

How long a maintenance organisation approval is valid?

unlimited duration

If a mechanic is using a Torquemeter, what he must check first?

A commercial transport aircraft is equipped with a set of service points for system servicing and refilling of system fluids (liquid or gaseous). Mention 5 examples of such service points.

  • Portable water filling
  • IDG Oil filling
  • APU Oil filling
  • Engine Oil filling
  • Hydraulic Oil filling (Bremsflüssigkeit)
  • Oxygen System
  • Toilet Servicing (leeren)

The basic structure of a commercial transport aircraft is mainly made of Aluminium alloys. On which structural components no Aluminium alloy is used and what instead?

  • Tital alloy (engine)
  • Engine Pylon, engine disks

Composite materials are also extensively used in aircraft structures. Mention 3 examples of aircraft parts, which are most commonly produced with composite materials.

  • flaps, flap track fairings, spoiler, belly fairing
  • radome, stabilizer, L/G doors, naccelle rowlings

A line maintenance engineer shall exchange one of several identical components on an aircraft. He will be able to identify the component’s location by means of the

  • Major zone, zone and sub zone numbers
  • FIN number (Functional Identification Number)

Aircraft systems and structures are identified by means of a specific classification system. Name it.

ATA chapters (Air Transport Assocciation System)

For maintenance purposes, mainly related to the landing gear, four jacking points are provided. Where have they located?

  • one below each wing
  • one in front of the nose landing gear bay
  • one safety point under the rear fuselage point

The air conditioning system basically ensures

  • temperatur regulation
  • ventilation and pressurisation

Which are the controllers related to the pressurization system?

CPC 1 & CPC 2

Correct cabin pressurization is obtained by controlling the conditioned air discharge through

two outflow valves

Which and how many valves do prevent excessive positive or negative differential pressure?

  • Two Safety Valves (installed on aft pressure dome)
  • One Negative Pressure Relieve Valve (installed on FWD Fuselage)

Mention 5 communication systems installed on A330 Aircraft.

  • 2 HF / 3VHF Systems
  • SELCAL (selective calling)
  • ACARS (Aicraft Communication Addressing and Reporting System)
  • SATCOM System
  • Passenger Address System
  • CIDS (Cabin Intercommunication Data System)
  • IFE
  • Interphone communication System
  • Cockpit Voice Recorder
  • CPDLC

For what reason interphones are used – mention 3

  1. Cabin interphone (Cabin - Cockpit)
  2. Flight interphone (Ground engineer)
  3. Service interphone (com. between verious interphones)

Mention the possible supply sources for the aircraft’s electrical systems

Melde dich an, um Bilder anzusehen.

AC electrical power supplied to the aircraft systems has following voltage/frequency characteristics:

115V / 400Hz

How many Batteries are installed (name it)?

3 Batteries (2 Main Batteries BAT 1+2; 1 APU Battery)

How are the main electrical systems feeded if during flight both IDG and the APU Generator fails?

With the Emergency Generator (Constant Speed Motor / Generator) driven by the green hydraulic system & RAT activation

What are the aircraft equipment and furnishings?

- the cockpit
- the passenger compartment
- the cargo compartments
- the avionics compartment
- the emergency equipment

What is the Nacelle and what is the purpose of it?

- Nacelle is the aerodynamic structure around the basic engine (Nose Cowl or Intake Cowl, Fan Cowls, Thrus Reverser, Exhaust Nozzle and Exhaust Plug)
- The purpose is to prevent damage to the basic engine, to smoothout the Fan Air Flow, give additional strenght to the engine structure.
