Operation of Aircraft Systems
Written by Jack on May 31st, 2008
| Objectives: |
To familiarize the student with the operation of various aircraft systems so that the student may have a better understanding of his aircraft. |
| Content: |
- Powerplant
- Reciprocating engines
- Radial, In-line, V-Type, Opposed
- Liquid or air cooled
- 4-stroke operating cycle (Intake, Compression, Power, Exhaust)
- Propeller
- Angle of incidence – for prop, angle formed by chord line and reference plane containing prop hub
- Fixed Pitch Propeller (2 types)
- Climb Propeller
- Cruise Propeller
- Tachometer as indicator of engine power
- Lower density, less power
- Controllable Pitch Propeller
- Constant Speed Propeller
- Acts as fixed pitch prop when pitch stops contacted
- Manifold pressure as indicator of engine power (MAP)
- For given RPM there is Manifold pressure that shouldn’t be exceeded (accordance w/ mfcr)
- Induction Systems (2 types)
- Carburetor system
- Float-type and pressure-type
- Icing most likely @ temps < 70?F (21?C) relative humidity > 80%
- Carb Heat in float-type
- Fuel injection system
- Superchargers
- Increase service ceiling
- Sea level engine (sea level supercharger)
- Altitude Engine
- Turbosuperchargers
- Critical altitude
- Turbine and compressor
- Waste gate
- Intercooler
- Overboost
- Excessively rich mixture causes carbon buildup/spark plug fouling
- Excessively lean mixture causes detonation

- Ignition System
-
- Dual ignition systems
- Combustion
- Detonation
- Preignition
- Fuel Systems (figures 5-15, 5-17 PHAN)
- Gravity-fed
- Fuel-pump, primer, tanks, gauges, selectors, strainers, sumps, and drains
- Fuel Grades
- Refueling procedures
- Starting System
- Oil Systems
- Recip. Engines use wet sump or dry sump oil system
- Engine Cooling Systems
- Cowl flaps
- Cylinder Head Temperature Guage (CHT)
- Exhaust Systems
- Exhaust Gas Temperature (EGT) and leaning
- Electrical Systems
- 14- or 28-volt direct current system
- Ground Power Unit (GPU) receptacle
- Alternator/Generator
- Ammeter/Loadmeter
- Voltage regulator
- Hydraulic Systems
- Single- or double-acting servos
- Landing Gear
- Tricycle (Nosewheel)
- Conventional (Tailwheel)
- Brakes
- Autopilot

See PHAN C. 5 Figures |
| Completion Standards: |
The lesson is complete when the instructor determines that the student has adequate knowledge of the aircraft systems by giving an oral or written exam. |
Posted in CFI Lesson Plans |
This is my first time on your web site (very nice & thanks). I am a recently minted CFI, CFII in central Oregon and need to train a student for a High Performance endorsement. This is my first time giving this training, and was looking for a comprehensive lesson plan specifically for this(so I dont miss anything). I still have not found one. Can you help? I appreciate your resource site and any help if possible. Thanks again. Chris Bryant
