Systems exam this month........feedback
1.Generators are connected
• in parallel to increase voltage
• in parallel to increase power
• in series to increase voltage
• in series to increase power
2.Alternators are connected in
• parallel
• series
• dependant upon engine
• dependant upon generator
3. Measurements of real and reactive loads in an ac generator are
• watts and amps
• amps and volts
• KVA and KVR
3.When testing a fire detection system
• the lights only are tested
• the extinguishers only are tested
• the detection loops only are tested
• the lights and the loops are tetsted
4. When the mixture lever is pulled to lean
• air flow to the combustion chamber reduces
• fuel flow to the combustion chamber reduces
• air flow to the carburettor reduces
• fuel flow to the carburettor reduces
5. Torsional loads in an aircraft wing are caused by?
• Dihedral
• Wing tip vortices
• Positive sweep
6.The pressure relief valve in oxygen system
• reduces pressure in the tank so the the pressure in the manifold is at a reasonable level for the user
• is used following the failure of the normal pressure reducing valva
7.regarding a diluter demand system, oxygen is
• mixed with air in the passengers mask (not crew)
• received when the user inhales
8.a question about engine capacity I think with the likeliest answer (I think)
• Vloume per cylinder x number of cylinders
9.what mixture would give max egt?
• 1:9
• 1:1/15:1
• cruise settin
• idle
CAN ANYONE REMEMBER ANYMORE??
