Systems Midterm Review

The function of the cylinders in a reciprocating engine are to

• House the piston

• Provide a combustion chamber

• Neither of these

• Both of these

What are the advantages of a fuel injection system?

• Less susceptible to fuel icing

• Use less fuel than carburetor equipped engines

• Generally produce more engine power

• All of the above

What happens when operating a reciprocating engine with the mixture too rich?

• Oil leaks throughout the engine compartment

• Carbon is left behind and builds up causing fouled spark plugs

• Too much air is pulled in through the induction system

• Not enough air reaches the engine

What kind of wing design is most common in jet aircraft?

• Elliptical

• Straight

• Swept

• Tapered

Turbojets can obtain a substantial increase in thrust by employing

• Afterburner

• Reverse thrust

• Rockets

• Fuel injection

What kind of flaps does the Cirrus SR20 have?

The monocoque construction method is best described as

• Two pieces of stretched skin to compose the aircraft structure

• Many pieces of skin fabric to make an aircraft structure secure

• One piece of stressed skin as the main structural component

• Sheets of honeycomb material affixed to internal spars and ribs

What is the purpose of an octane rating for fuel?

• Determine the fuel’s resistance to detonation

• Make fuel available at lower prices by decreasing the level of grade

• Give the fuel a name for easy classification

• Make aviation fuel more readily available in general aviation aircraft

What causes adverse yaw?

• The working aileron creates more parasite drag and thus pulls that side back

• An aileron moving downward creates more lift, thus more drag and pulls the nose in the opposite direction

• Over banking causes the aircraft to be unstable and skid

• Introduction of induced drag due to rapid aileron movement
