2.1 Powerplant — Williams FJ33-5A & FADEC

DRAFT lesson page — content pending POH verification and video production.

Learning Objectives

• Describe the Williams FJ33-5A and how FADEC manages it
• Perform normal start and shutdown and monitor the correct indications
• State engine limits — N1/N2, ITT, oil ‹VERIFY POH›
• Recognize abnormal starts (hot / hung) and FADEC’s protective response

In This Lesson

• One engine, mounted high on the spine; FADEC manages fuel, start, and limits
• You command thrust; the FADEC protects the engine
• Normal start sequence and the indications you monitor
• Engine limits to protect ‹VERIFY POH›
• Abnormal starts — hot and hung — and auto-abort logic
• Shutdown and securing

Video

In production — original FADEC & start-sequence animation + Austin ground-start gauge footage + AI voiceover.

Knowledge Check

• FADEC stands for Full Authority Digital Engine Control
• Engine make and model: Williams FJ33-5A
• During start the pilot primarily monitors the engine
• ITT and RPM limits ‹VERIFY POH›
• A hung start is RPM stagnating below idle
