Chapters

CHAPTER 1 · Syllabus 17.1 · level 2
How a Propeller Makes Thrust
Blade element theory, blade angle and angle of attack, the relative airflow a blade section sees, geometric and effective pitch, slip and efficiency, and the range of blade angles from reverse to feather.
🎬 7 slides📖 ~35 min🃏 18✅ 18 Q
Not startedCHAPTER 2 · Syllabus 17.1 · level 2
Forces, Torque, Vibration and Resonance
The loads a turning propeller carries — centrifugal force, thrust and torque bending, centrifugal and aerodynamic twisting moments — then torque reaction, slipstream, P-factor and gyroscopic precession, and how vibration and resonance arise and are controlled.
🎬 7 slides📖 ~30 min🃏 15✅ 14 Q
Not startedCHAPTER 3 · Syllabus 17.2 · level 2
Propeller Construction and Materials
How wooden, aluminium alloy, steel and composite propellers are built, and the names of every part of a propeller — hub, shank, butt, blade face and back, leading and trailing edge, tip and blade stations.
🎬 6 slides📖 ~30 min🃏 16✅ 15 Q
Not startedCHAPTER 4 · Syllabus 17.2 · level 2
Propeller Types and Installation
Fixed-pitch, ground-adjustable, controllable-pitch, constant-speed, feathering and reversing propellers; tractor, pusher, contra- and counter-rotating layouts; and how propellers and spinners are fitted to flanged, tapered and splined shafts.
🎬 7 slides📖 ~30 min🃏 16✅ 14 Q
Not startedCHAPTER 5 · Syllabus 17.3 · level 2
Governors and Constant-Speed Operation
How a propeller governor senses rpm with flyweights against a speeder spring and moves a pilot valve to send oil to or from the hub; on-speed, underspeed and overspeed conditions; single- and double-acting systems; and how non-feathering single-engine propellers are built.
🎬 7 slides📖 ~35 min🃏 16✅ 16 Q
Not startedCHAPTER 6 · Syllabus 17.3 · level 2
Feathering, Reverse and Overspeed Protection
Feathering and unfeathering of light-twin and Hydromatic propellers, autofeather, the beta range and reverse pitch on turboprops, PT6-type and electronically controlled propeller systems, and the devices that protect against overspeed: overspeed governors, pitch locks and flight-idle stops.
🎬 7 slides📖 ~40 min🃏 18✅ 18 Q
Not startedCHAPTER 7 · Syllabus 17.4 · 17.5 · level 2
Synchronising and Ice Protection
How multi-engine aircraft keep their propellers at the same speed and in a fixed phase relationship to cut noise and vibration, active noise suppression, and how propellers are protected from ice with fluid anti-icing and electrical de-icing — including inspection and testing of brush blocks, timers and overshoes.
🎬 7 slides📖 ~35 min🃏 18✅ 20 Q
Not startedCHAPTER 8 · Syllabus 17.6 · level 3
Inspection, Damage Assessment and Repair
How wooden, aluminium, steel and composite propellers are inspected, how to judge erosion, corrosion, nicks, cracks, impact damage and delamination against limits, what to do after a ground strike, and the minor and major repair and protective treatment schemes used on blades.
🎬 7 slides📖 ~40 min🃏 17✅ 18 Q
Not startedCHAPTER 9 · Syllabus 17.6 · 17.7 · level 2–3
Tracking, Balancing, Ground Running and Storage
Checking blade track and blade angles with the universal propeller protractor, static and dynamic balancing, propeller engine ground runs and troubleshooting, and how propellers, governors and accumulators are preserved, stored and returned to service.

The Module 17A paper
Category B1: 32 multiple-choice questions in 40 minutes. Category A: 20 questions in 25 minutes. Module 17 is not part of the B2 licence; B3 sits the separate Module 17B. That is a nominal 75 seconds per question, pass mark 75%, no negative marking. The per-sub-module numbers in the table are the recommended distribution in the AMC to Part-66 / CAR-66 Appendix II.
B1 depth
B1 needs level 2 for every sub-module except propeller maintenance, which is level 3 — expect detailed questions on damage limits, tracking, balancing, blade angle checks and engine ground runs. Know which way the blades move for each governor condition, and what drives a blade to feather.
How to use this course
1) Watch the chapter explainer for the big picture. 2) Read the lesson and study every diagram — Module 17 is about forces, oil flows and blade angles. 3) Walk the mind map and flip the flashcards the next day. 4) Take the chapter quiz until you score 75% or more. 5) When every chapter is green, sit the timed mock exam and review every wrong answer.
