Answer 1

Plain flaps

Question 2

Trim

Answer 2

Anti servo trim.
Goes in the same direction of stabilator just further.
Used when controls are usually too easy to move.

Question 3

Engine

Answer 3

LHAND
L: Lycoming 0-360-A4M
H: Horizontally Opposed
A: Air cooled
N: Naturally Aspirated (the engine relies on atmospheric pressure alone to draw in air for combustion.)
D: Direct Drive (crankshaft connected directly to the propeller)

Question 4

Horse Power and Max RPM

Answer 4

180 horsepower at 2700 RPM

Question 5

Ignition system

Answer 5

Engine ignition is provided through the use of two engine driven magnetos, which are
independent of the aircraft’s electrical system and each other.
Redundancy and increased performance.

Question 6

Answer 7

25 on each side, 24 usable
50 total 48 total usable.
Tabs 17gal

Question 8

Spark plugs

Answer 8

There are 8 spark plugs that provide spark for
combustion.
2 spark plugs per cylinder, for increased
reliability, power, and even combustion.

Question 9

Propeller

Answer 9

Sensenich two-bladed, fixed pitch, metal propeller.
Propeller diameter is 76 inches.
Maximum RPM is 2700 RPM

Question 10

Carb heat

Answer 10

When on, the outside air runs over the engine exhaust muffler, which heats the air. When on, it switches the valve allowing the heated air into the carburetor instead of the normal outside air.

Question 10

Answer 10

28 volt DC

Question 11

Battery

Answer 11

24 volt lead acid battery
can provide 35 amps per hour.

Question 12

Alternator

Answer 12

28volt, 70-amp, engine driven alternator. A voltage regulator maintains a constant 28 volt output.
It powers the electrical system.
Output is displayed on the ammeter

Question 13

Display

Answer 13

G1000 primary avionics with a Aspen Evolution as backup display.
G1000 has the PFD and MFD.
PFD replaces the 6 pack
MFD provides nav and engine indicators.

Question 14

AHRS

Answer 14

Attitude and Heading Reference System
Replaces traditional gyros with MEMS

Question 15

MEMS

Answer 15

M: Micro
E: Electro
M: Mechanical
S: System

Question 16

Magnetometer

Answer 16

Measures magnetism and direction, strength or relative change of magnetic field at a particular location.
It senses the magnetic field and sends it to the ARHS which processes it to determine magnetic heading.
Located on the left wing.

Question 17

ADC

Answer 17

Air Data Computer
Uses the static pitot with total air temp to calculate IAS & TAS, OAT and vertical speeds. Transmits that info to EFIS (ASI, VSI & Altimeter) and autopilot and transponder.

Question 18

GPS

Answer 18

Approved for approach procedures with vertical guidance (LPV WAAS GPS, LNAV/VNAV, and LNAV +V)

Question 19

RAIM

Answer 19

Receiver Autonomous Integrity Monitoring
5 satellites for RAIM
4 satellites for 3D nav
3 satellites for 2D nav
4 satellites provide while a 5th monitors the 4 satellites

Question 20

RAIM vs WAAS

Answer 20

RAIM can shoot LNAV but not LNAV/VNAV, alternate needs to have other than GPS approach.
WAAS can shoot LNAV, LNAV/VNAV and LPV. Your alternate can be GPS only approaches. Preflight RAIM not needed with WAAS.
