Answer 4

tricycle type
shock absorption- tubular spring-steel main landing gear struts and air/oil nose gear shock strut.
brakes= hydraulically actuated disc type

Question 5

Brakes

Answer 5

Single-disc hydraulically actuated brake on each main.
connected by hydraulic line to the master cylinder.

Question 6

Fuel system

Answer 6

two tanks ( 13 each) 22.5 useable-135lbs
vented tanks, fuel shut off, strainer, manual primer, and carburetor.

fuel goes thru strainer to carb(mixes w/ air) to cylinders through intake manifold tubes.
* primer draws from STRAINER directly to intake manifold.

Question 7

How does the fuel system vent

Answer 7

interconnecting line from the right to left tank.left tank is vented overbroad thru vent line which has a check valve. sticks out from the bottom of the left wing
right tank cap is vented.

Question 8

How much unusable fuel is stored

Answer 8

3.5 gal
because the fuel lines sit higher then bottom of tanks

Question 9

How is fuel quantity measured

Answer 9

2 float type transmitters and indicated by 2 electrically operated fuel quantity indicators on the lower portion of the panel.

Question 10

Where is the fuel strainer drain located

Answer 10

under access panel on right side of cowling
tanks should be filled each flight to prevent condensation

Question 11

How is electricity powered to the airplane

Answer 11

by a 14 volt DC system powered by engine driven Go-amp alternator.
12V/25Amp hour battery located right forward side of firewall.
power is supplied to a single bus bar, master switch controls all circuits except ignition system, optional clock and flight recorder.

Question 12

Describe the bus bar

Answer 12

like a power strip
Single bus
Master switch controls power to all circuits except engine ignition system, flight hour recorder and clock.

Question 13

Flight hour recorder

Answer 13

receives power through activation of oil pressure switch whenever engine is operating

Question 14

what happens when Alternator malfunctions

Answer 14

Electrical load exceeds the output of the alternator, the ammeter will indicate battery discharge rate

Question 15

explain over voltage condition in electrical system

Answer 15

the sensor will automatically remove the alternator field current and shuts down the alternator. the red warning light will then turn on.
can be reset by cycling master switch.

Question 16

which components are powered by fuses not circuit breakers

Answer 16

battery contactor closing(external power) circuit, flight hour recorder circuits which have fuses mounted by the battery.

Question 17

explain the vacuum system

Answer 17

engine driven system provides suction to operate the attitude indicator and directional indicator.
pump is mounted on engine , vacuum relief valve and air filter on aft side of firewall.

Question 18

describe suction gauge

Answer 18

indicates the measure of mercury and amount of suction available for the attitude/directional indicator.
desired rate is 4.6 to 5.4 inches.

Question 19

describe the pitot static system

Answer 19

supplies ram pressure to the airspeed indicator and static pressure to the airspeed indicator, rate of climb indicator and altimeter.
has a heating element on a 10amp ck breaker.

Question 20

describe airspeed indicator

Answer 20

flaps white arc 49-100mph

normal operating range green arc 56-120mph

caution yellow arc 120-162mph

never exceed red line - 162 mph

Question 21

Stall warning horn

Answer 21

pneumatic type
inlet is in the leading edge of the wing.
air operated horn sounds 5 to 10 kts above stall speed.
low pressure over the wing creates a differential pressure (vacuum) which draws air to thru the horn.

Question 22

gross weight

Answer 22

max allowable weight of both airplane and its contents
1600lbs

Question 23

useful load

Answer 23

weight of the pilot, passengers,cargo,fuel and other equipment and drainable oil
625lbs

Question 24

wing loading

Answer 24

10.2 pounds per sqft

Question 25

ground run at sea level

Answer 25

735ft

Question 26

total distance over 50ft at sea level

Answer 26

1385ft

Question 27

max baggage load

Answer 27

120lbs

Question 28

ammeter

Answer 28

indicated current flow in amperes.from the alternator to the battery or from the battery to the aircraft elcetrical system.will have a discharge rate indication when not working.

Question 29

electrical system

Answer 29

3 circuit breakers. push to reset labeled”alt” on left side of instrument panel.protects the alternator circuit. the field and wiring is protected by an automatic resetting breaker mounted on panel

Question 30

Answer 30

flaps up - 4.4
flaps down- 3.5

Question 31

max oil temp

Answer 31

240f

Question 32

where is the fuel strainer drain

Answer 32

under access panel on right side of the engine cowling
fuel tanks should be filled after each flight to prevent condensation

Question 33

directional(heading) indicator

Answer 33
