injects fuel directly into the cylinder intake ports

how does the vacuum system work?

inlet air goes into the vacuum air filter, directly to the instruments, sucked by the vacuum pump through the vacuum relief valve, and discharged out the overboard vent line

inside the cabin has there is lower static pressure than outside

what happens to the airspeed indicator if the static port becomes blocked?

it becomes reverse- shows higher airspeed when climbing and lower airspeed when descending

lower right and upper left spark plugs

no

what are the operating ranges of the engine RPM?

normal- 2200-2700 rpm (green arc) maximum- 2700 rpm (red line)

when are seat belts required for passengers?

only during taxi, takeoff, and landing

where does all electrical energy go through in the aircraft?

power is supplied to most general electrical and all avionics circuits through the primary bus bar

why do you use a control lock?

protect the aileron and elevator control systems from winds while parked

how does the fuel selector valve work?

pulls gas from desired wings using gravity flow and leads the gas to the fuel strainer

how does the alternate static source work?

pulls static pressure from inside the flight deck

what does the pitot tube measure?

ram air pressure

what is the purpose of the hobbs?

record total time an aircraft is being used

what does the master switch control?

right half controls all electrical power to the airplane and the left half controls the altimeter

where do you find engine oil grades and specifications?

section 8 of the POH

how does the vertical speed indicator work?

static air pressure from the static port increases or decreases the size of the diaphragm (depending on the climb or decent) which then turns the dual the reads the vertical speed of the aircraft

does the vacuum system suck air in or push air out?

sucks air in

when is the fuel selector BOTH used?

takeoff, landing, climb, and maneuvers that involve prolonged slips or skids

when should the high intensity strobe lights be turned off?

taxiing in the vicinity of other aircrafts or during night flight through clouds, for, or haze

how is the ram air exhausted through engine cowling?

through an opening at the bottom aft edge

where does the ram air enter the engine?

through the engine intake on the front of the engine cowling

what is the purpose of the tachometer?

to record engine time

where does the gas flow from the fuel strainer?

to the engine primer or carburetor

what type of landing gear is used?

tricycle landing gear

what is the procedure if a cabin door is opened during flight?
