Engine Exhaust W
FAA Exhaust Written Questions/Answers
| Question | Answer |
|---|---|
| On a reciprocating engine aircraft using a shrouded exhaust muffler system as a source for cabin heat, the exhaust system should be | Visually inspected for any indication of cracks or an operational carbon monoxide detection test should be done. |
| Why is nickel chromium steel used in many exhaust systems? | Corrosion resistance and low expansion coefficient |
| Reciprocating engine exhaust system designs commonly used to provide for ease of installation and/or allow for expansion and contraction, may include use of | 1. Spring loaded ball/flexible joints, 2. Slip joints, 3. Bellows |
| What is the purpose of a slip joint in an exhaust collector ring? | It aids in alignment and absorbs expansion |
| What type nuts are used to hold an exhaust system to the cylinders? | Brass or heat resistant nuts. |
| Repair of exhaust system components | is not recommended to be accomplished in the field |
| On an aircraft that utilizes an exhaust heat exchanger as a source of cabin heat, how should the exhaust system be inspected? | With the heater air shroud removed |
| How should ceramic coated exhaust components be cleaned? | By degreasing |
| Select a characteristic of a good weld on exhaust stacks | The weld should taper off smoothly into the base metal |
| How should corrosion resistant steel parts such as exhaust collectors be blast cleaned? | Use sand which has not previously been used on iron or steel. |
| Reciprocating engine exhaust systems that have repairs or sloopy weld beads which protrude internally are unacceptable because they cause | local hot spots |
| Ball joints in reciprocating engine exhaust systems should be | loose enough to permit some movement |
| All of the following are recommended markers for reciprocating engine exhaust systems except | lead pencil |
| Augmenter tubes are part of which reciprocating engine system? | Exhaust |
| Dislodged internal muffler baffles on a small recip engine may | obstruct the muffler outlet and cause excessive exhaust back pressure |
| What is the purpose of an exhaust outlet guard on a small reciprocating engine? | To prevent dislodged muffler baffles from obstructing the muffler outlet |
| What could be a result of undetected exhaust system leaks in a reciprocating engine powered airplane? | Pilot/passenger incapacitation caused by carbon monoxide entering the cabin |
| How may reciprocating engine exhaust system leaks be detected? | Signs of exhaust soot inside cowling and on adjacent components |
| Compared to normally aspirated engines, turbocharged engine exhaust systems operate at | higher temperatures and higher pressures |
| Most exhaust system failures result from thermal fatigue cracking in the areas of stress concentration. This condition is usually caused by | the high temperatures at which the exhaust system operates |
| On turbojet powered airplanes, thrust reversers are capable of producing between | 35% and 50% of the rated thrust in the reverse direction |
| Operating thrust reversers at low ground speeds can sometimes cause | 1. Sand or other foreign object ingestion, 2. hot gas re-ingestion, 3. compressor stalls |
| Engines using cold stream, or both cold and hot stream reversing include | High bypass turbofans |
| The purpose of cascade vanes in a thrust reversing system is to | turn to a forward direction the fan and/or hot exhaust gases that have been blocked from exiting through the exhaust nozzle |
| Turbojet and turbofan thrust reverser systems are generally powered by | 2. electricity, 3. hydraulic pressure, 4. pneumatic pressure |
| The rearward thrust capability of an engine with the thrust reverser system developed is | less than its forward capability. |
| Which statement is generally true regarding thrust reverser systems? | It is possible to move some aircraft backward on the ground using reverse thrust |
| What is the proper operating sequence when using thrust reversers to slow an aircraft after landing? | Retard thrust levers to ground idle, raise thrust reverser levers as required, and retard thrust levers to ground idle |
| The exhaust section of a turbine engine is designed to | impart a high exit velocity to the exhaust gases |
| Thrust reversers utilizing a pneumatic actuating system usually receive operating pressure from | the engine bleed air system |
