Aircraft maintenance requires precision, with separate specialties for mechanical and electronic systems. The B2 Basic Toolkit equips B2 certified avionics engineers with the tools needed to maintain and repair aircraft electrical systems.

B1 vs B2 Certification:
- Engineer B1: Specialized in mechanical maintenance (engine, airframe, hydraulics, fuel system).
- Engineer B2: Focus on avionics (electrical systems, communications, navigation, autopilot).

Purpose of the B2 Basic Toolkit:
Designed for avionics system diagnosis, repair and maintenance, the B2 Basic Toolkit supports in-depth testing and complex repairs.

Main tools in the B2 Basic Toolkit:
1. Electrical and electronic tools:

• Multimeter – Measures voltage, current, resistance.
• Oscilloscope – Electronic signal analysis.
• Wire strippers, crimping pliers, soldering iron – Essential for electrical work.
• Precision Screwdriver – For small components.
• Continuity Tester – Check connections.
  

2. Testing tools:

• Endoscope – Inspect hard-to-reach areas.
• Digital Microscope – Circuit Board Inspection.
• Thermal Imager – Detects overheating.

3. Specialized avionics tools:

• Pitot Static Test Kit – Airspeed Test, Altimeter.
• Loop Tester – Test communication systems.
• RF Analyzer – Radio Frequency Test.
• Calibration Tools – Ensuring the accuracy of avionics.
• Cable Tester – Identify wiring system faults.

4. Wiring system tools:

• Wire Harness Tester – Checks the integrity of the wiring system.
• Labeling Machine – Wire Organizer.
• Heat Gun – Apply heat shrink tubing.

5. Diagnostic Software & Equipment:

• Avionics Diagnostic Tablet – Loaded with dedicated software.
• Interface cable – Connects diagnostic tools.

6. Common tools (Shared with Set B1):

• Hand tools – Pliers, cutters, wrenches.
• Torque wrench – Secures the shields.

7. Personal protective equipment (PPE):

• Anti-static straps, mats – Prevent static discharge.
• Insulating gloves – Protection against high voltage.

Importance of both toolkits:
Modern aircraft require both mechanical and electronic expertise. Specialized toolkits ensure complete maintenance and safety.

The Base B2 Toolkit is a vital resource for avionics engineers, equipping them with essential tools for electrical and electronic maintenance. Together with the Base B1 Toolkit, it ensures aircraft reliability and safety.
