|
|
Term
| WHAT ARE TWO TYPES OF FUEL CELLS THAT ARE USED IN MODERN AIRCRAFT? |
|
Definition
| BLADDER TYPE AND INTEGRAL TYPE. |
|
|
Term
| WHY ARE FUEL TANKS DIVIDED INTO COMPARTMENTS OR HAVE BAFFLES INSTALLED IN THEM? |
|
Definition
| KEEPS THE FUEL FROM SURGING BACK AND FORTH AS THE AIRCRAFT CHANGES ITS ALTITUDE IN FLIGHT. |
|
|
Term
| WHAT IS MEANT BY AN INTEGRAL FUEL CELL? |
|
Definition
| PART OF THE STRUCTURE THAT BECOMES THE FUEL TANK. |
|
|
Term
| WHERE ARE FUEL SYSTEM STRAINERS LOCATED? |
|
Definition
| OUTLET TO THE TANK AND IN THE FUEL LINE BETWEEN THE OUTLET OF THE FUEL TANK AND THE INLET TO THE FUEL METERING DEVICE. |
|
|
Term
| WHAT ARE THREE USES OF A CENTRIFUGAL BOOSTER PUMP THAT IS INSTALLED IN AN AIRCRAFT FUEL TANK? |
|
Definition
- PRODUCE FUEL PRESSURE TO START THE ENGINE
- PREVENT VAPOR LOCK AT HIGH ALTITUDES
- TRANSFER FUEL FROM ONE TANK TO ANOTHER.
|
|
|
Term
| WHAT IS MEANT BY A COMPENSATED ENGINE DRIVEN FUEL PUMP? |
|
Definition
| VARIES OUTLET FUEL PRESSURE SO IT WILL STAY A CONSTANT AMOUNT HIGHER THAN THE PRESSURE OF THE AIR THAT IS ENTERING THE CARBURETOR. |
|
|
Term
| WHY DO ENGINE DRIVEN FUEL PUMPS HAVE A BYPASS VALVE IN THEM? |
|
Definition
| ALLOWS FUEL FROM THE BOOSTER PUMP TO FLOW AROUND THE ENGINE DRIVEN PUMP MECHANISM FOR STARTING THE ENGINE, AND TO SUPPLY THE ENGINE WITH FUEL IF THE ENGINE DRIVEN PUMP FAILS. |
|
|
Term
| WHY MUST AN AIRCRAFT FUEL VALVE HAVE A DETENT IN ITS OPERATING MECHANISM? |
|
Definition
| TO GIVE THE PILOT A POSITIVE INDICATION BY FEEL WHEN THE SELECTOR VALVE IS IN THE FULL ON OR OFF POSITION. |
|
|
Term
| WHAT CHARACTERISTIC OF THE FUEL IS MEASURED WITH THE MASS-FLOW FUEL FLOWMETER THAT IS USED WITH TURBINE ENGINE AIRCRAFT? |
|
Definition
|
|
Term
| WHAT IS USED AS A FLOW METER FOR A FUEL INJECTED HORIZONTALLY OPPOSED AIRCRAFT ENGINE? |
|
Definition
| PRESSURE GAUGE THAT MEASURES THE PRESSURE DROP ACROSS THE INJECTOR NOZZLES. |
|
|
Term
| WHAT IS MEANT BY A CROSSFEED SYSTEM IN AN AIRCRAFT FUEL SYSTEM? |
|
Definition
| ALLOWS FUEL FROM ANY TANK TO FLOW TO ANY ENGINE. |
|
|
Term
| WHY DO SOME AIRCRAFT HAVE PROVISIONS FOR JETTISONING FUEL IN FLIGHT? |
|
Definition
| SOME AIRCRAFT HAVE A HIGHER TAKE OFF WEIGHT THAN ALLOWABLE LANDING WEIGHT, JETTISONING ALLOWS ENOUGH FUEL TO BE DUMPED TO BRING THE WEIGHT DOWN FOR LANDING IN CASE OF EMERGENCIES. |
|
|
Term
| WHAT MUST BE DONE TO A WELDED FUEL TANK BEFORE IT CAN BE REPAIRED BY WELDING? |
|
Definition
| ALL FUEL VAPORS MUST BE PURGED, BY FLOWING STEAM, SOAKING IN BOILING WATER, OR CHEMICALLY NEUTRALIZING THE FUMES. |
|
|
Term
| WHAT SAFETY PRECAUTIONS MUST BE TAKEN BEFORE A PERSON ENTERS THE FUEL CELL OF A LARGE AIRCRAFT? |
|
Definition
| CELL FUMES PURGED, HAVE PROPER SAFETY EQUIPMENT, HAVE A PERSON STANDING BY THE OUTSIDE OF THE CELL. |
|
|
Term
| WHAT IS MEANT BY A SINGLE POINT FUELING SYSTEM? |
|
Definition
| A PRESSURE FUELING SYSTEM IN WHICH FUEL IS PUMPED INTO THE AIRCRAFT THROUGH A UNDER WING FUELING PORT AND CAN CHOOSE WHAT TANK TO SEND FUEL TO. |
|
|
Term
| WHAT GAS IS USED TO PURGE A FUEL TANK OF ALL FUEL VAPORS? |
|
Definition
| CARBON DIOXIDE OR NITROGEN. |
|
|
Term
| WHY DO TURBOJET AIRCRAFT NORMALLY HAVE FUEL TEMPERATURE INDICATORS? |
|
Definition
| TO DETECT POSSIBLE FREEZING FROM WATER PARCIPITATION FROM THE FUEL. |
|
|
Term
| HOW IS A FUEL LEAK INDICATED ON A RECIPROCATING ENGINE POWERED AIRCRAFT? |
|
Definition
| THE DYE IN THE FUEL STAINS THE AREA AROUND THE LEAK. |
|
|
Term
| WHAT IS THE PURPOSE OF THE DRIP GAUGE IN THE FUEL TANK OF LARGE AIRCRAFT? |
|
Definition
| ALLOWS A MECHANIC TO CHECK THE FUEL LEVEL IN A TANK FROM THE BOTTOM OF THE TANK. |
|
|
Term
| WHAT SAFETY PRECAUTIONS SHOULD BE TAKEN BEFORE AN AIRCRAFT IS DEFUELED? |
|
Definition
- FUEL TRUCK PROPERLY LOCATED
- FUEL TRUCK AND AIRCRAFT ARE ELECTRICALLY GROUNDED
- ALL ELECTRICAL POWER NOT NEEDED FOR DEFUEL IS TURNED OFF
- FUEL IS RETURNED TO PROPER TRUCK OR CONTAINER.
|
|
|
Term
| WHAT MARKINGS MUST APREAR NEAR THE FILLER OPENING OF THE FUEL TANKS ON RECIPROCATING-ENGINE POWERED AIRCRAFT, AND TURBINE-ENGINE POWERED AIRCRAFT? |
|
Definition
- RECIPROCATING- THE WORD FUEL AND MINIMUM GRADE OF FUEL
TURBINE- THE WORD FUEL AND PERMISSABLE FUEL DESIGNATIONS, MAXIMUM PERMISSABLE FUELING SUPPLY PRESSURE, AND MAXIMUM PERMISSABLE DEFUELING PRESSURE. |
