Seperate false 345 346 an external tank may be formed

SEPERATE ( FALSE )
345 – 346. An external tank may be formed by spaces between frames or other cavities within the
engine. A store of fluid may also be held in a gearbox. INTERNAL ( FALSE )

347 – 348. A separate, external tank is usually constructed of sheet steel or stainless steel. ALLUMINIUM
( FALSE )
349 – 350. The tank is designed to furnish a constant supply of oil for all approved flight manoeuvres. (
TRUE )
351 – 352. Most oil reservoirs are unpressurised to suppress foaming and supply a head of pressure,
forcing the oil to the pump inlet. PRESSURISED ( FALSE )
353 – 354. An oil tank needs expansion space of at least 40% of the tank capacity. 10% ( FALSE )
355 – 356. Filling and replenishing the oil is done remotely or at the oil tank. DRAINING ( FALSE )
357 – 358. A filler cap is usually corporated for manual filling with oil cans. INCORPORATED ( FALSE )
359 – 360. Pressure and overflow ports may be included for filling from a pressure rig. ( TRUE )
361 – 362. The tank may have a low point of usable oil. This area collects any sediment and is the point
for draining the tank. UNUSABLE ( FALSE )
363 – 364. Vane pump - most common type consists of two meshed gears that rotate inside a housing
with minimum clearance between gear & housing. GEAR ( FALSE )
365 – 366. Gear pump - consists of a housing that contains a steel sleeve with off centre bore. 4 vanes,
hollow steel rotor and a coupling that turns the rotor. VANE ( FALSE )
367 – 368. Gerotor pump - consists of a an engine driven spur gear that rotates within a free spinning
rotor housing, the housing has two oblong openings (oil inlet & oil outlet). ( TRUE )
369 – 370. The oil scavenge pump may also be a gear, vane or gerotor type pump that is driven by the
generator. ENGINE ( FALSE )
371 – 372. In many reciprocating engine oil pumps, the pressure pump and scavenge pumps are often
enclosed in the one housing. TURBINE ( FALSE )
373 – 374. Pressure oil filters are positioned upstream from the oil pump. DOWNSTREAM ( FALSE )
375 – 376 - Spacer thickness determines particle width filtration. SIZE ( FALSE )
INNUMERATION :
377 – 379. Types Of Air Inlets
• SUBSONIC INLETS
• SUPERSONIC INLETS
• TURBOPROP INLETS
380 – 382. The typical turbosupercharger is composed of three main parts:
• COMPRESSOR ASSEMBLY
• TURBINE WHEEL ASSEMBLY
• A FULL FLOATING SHAFT BEARING ASSEMBLY
383 – 385. A sea level booster turbo supercharger system used widely is automatically regulated by
three components:
• EXHAUST BYPASS VALVE ASSEMBLY
• DENSITY CONTROLLER
• DIFFERENTIAL PRESSURE CONTROLLER

386 – 388. Types of bearings
• PLAIN BEARING
• ROLLER BEARING
• BALL BEARING
389 – 391. Types of Friction
• ROLLING FRICTION
• SLIDING FRICTION
• WIPING FRICTION
392 – 397. The principal units in a typical reciprocating engine dry sump oil system includes:
• AN OIL SUPPLY TANK
• AN ENGINE-DRIVEN PRESSURE OIL PUMP
• A SCAVENGE PUMP
• AN OIL COOLER WITH AN OIL COOLER CONTROL VALVE
• OIL TANK VENT, - NECESSARY TUBING
• PRESSURE AND TEMPERATURE INDICATORS.
