Module 14 Propulsion
B2/B2L turbine-engine principles, engine indication, starting and ignition, with the B2L applicability condition.
How to prepare for UK Part-66 basic-knowledge examinations
Fix the intended A, B1, B2, B2L, B3, L or C route; use the regulatory module matrix and knowledge levels; then rehearse the exact MCQ and essay components that apply to each selected module.
Core concepts
Concept 1
Module 14 gives avionics engineers the propulsion knowledge needed to maintain engine electrical, indication, start, ignition and electronic-control interfaces.
Exam cue: Trace each engine parameter from sensing point to displayed value.
Concept 2
Engine indication depends on sensors, wiring, processing and displays across mechanical and avionics boundaries.
Exam cue: Identify maintenance safety controls around starting and ignition.
Concept 3
For B2L, Module 14 applies only when seeking the Instruments or Airframe Systems rating.
Exam cue: Check the B2L rating before adding Module 14 to the route.
Risk pitfalls and guardrails
Adding Module 14 to every B2L system-rating application.
Guardrail: Do not mix Category A, B1, B2/B2L, B3 or Category L module variants, or treat the aggregate 601-item study allocation as an official CAA examination total.
Diagnosing the engine from a display without checking the indication chain.
Guardrail: Do not mix Category A, B1, B2/B2L, B3 or Category L module variants, or treat the aggregate 601-item study allocation as an official CAA examination total.
Ignoring stored energy and ignition hazards during maintenance.
Guardrail: Do not mix Category A, B1, B2/B2L, B3 or Category L module variants, or treat the aggregate 601-item study allocation as an official CAA examination total.
Memory anchors
B2 Propulsion
Module 14 provides propulsion-system context for avionics work.
Indication Chain
Sensor, wiring, processing and display all affect the parameter shown.
FADEC
Electronic engine control links computation, sensing, actuation and protection.
Start Safety
Control fuel, ignition, rotation and exclusion hazards before test.
B2L Condition
Module 14 is only for B2L Instruments or Airframe Systems.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
Knowledge Check (after reading)
Short check-up to confirm understanding of this module.
