Aviation 2100 Final review

Hypoxia

a state of Oxygen deficiency in the body, there are 4 types

4 types of hypoxia

hypoxic,

hypemic,

histotoxic,

stagnant

HyPOxic

due to decrease in Pressure at altitude; the body is not able to get enough Oxygen

HypEMiC

blood is not able to carry oxygen because of smoking, anEmia, Carbon Monoxide poisoning

HistoTOXIC

the body is not able to use the oxygen efficiently because of ALCOHOL

(Stag)nant

the body is not able to circulate blood effectively because of a Heart Attack (staggering) or g-forces

Hazardous Attitudes

Anti-authority

Impulsivity

Invulnerability

Macho

Resignation

Anti-Authority

"Don't tell me what to do"

Solution: Follow the rules they are usually right

Impulsivity

"Do something quickly"

Solution: not so fast! think first.

Invulnerability

"It won't happen to me"

Solution: It could happen to me

Macho

"I can do it!"

Solution: Taking chances is foolish

Resignation

"What's the use?"

Solution: I am not helpless. I can make a difference.

Special Disorientation

A lack of orientation regarding the position, attitude, or movement of the aircraft in space

How does Special disorientation happen?

VFR pilot flies into IMC

What is the Chord Line?

An imaginary straight line from the leading edge to the training edge of an airfoil

What is Relative Wind?

the direction of the wind in relation to the airfoil

What is Angle of Attack?

Angle between relative wind and the chord line

What are the 4 forces acting on an airplane in flight?

lift, weight, thrust, and drag

When are the 4 forces in equilibrium?

During unaccelerated straight and level flight

Density Altitude

The altitude the aircraft feels like it is at. So, a high density altitude would make the aircraft behave the same as if it were flying high in the mountains. Performance would suffer. Climbs rate would slow, and power would decrease.

What controls Roll?

Ailerons (longitudinal axis - lateral stability)

What controls Pitch?

elevator (lateral axis - longitudinal stability)

What controls Yaw?

rudder (Vertical axis - directional stability)

Why use Flaps on Approach and Landing?

to enable the pilot to make steeper approaches to a landing without increasing the airspeed

What is wake turbulence?

wingtip vortices created by large aircraft tend to sink below the aircraft generating turbulence

What is magnetic deviation?

error caused by magnetic fields within the aircraft distorting the lines of magnetic force

what is magnetic variation?

the angular difference between magnetic and geographic North

when is a compass most accurate?

only in straight-and-level unaccelerated flight

What instruments are connected to the pitot tube?

Airspeed indicator

what instruments are connected to the static port?

all 3 instruments: Vertical speed indicator (vsi), Altimeter, and airspeed indicator (asi)

what instruments become inoperative if pitot tube becomes clogged?

airspeed indicator

what instruments don't work if the static port is clogged?

all 3 instruments

On the airspeed indicator: what is the White arc?

flap operating range

On the airspeed indicator: what is the Green arc?

normal operating range

On the airspeed indicator: what is the Red Radial line?

never exceed speed

Indicated Altitude

read on instrument

True Altitude

the vertical distance of the aircraft above mean sea level (MSL)

Absolute Altitude

the vertical distance above the surface or above ground level (AGL)

Pressure Altitude

height above standard datum plane (29.92" Hg)

Why do aircraft separate the ignition and electrical systems?

The Electrical system powers the avionics and radios by using the battery and alternator to provide power.

The Ignition system powers the ignition (spark plugs) utilizing two independent magnetos providing reliability

If you had an electrical failure (battery and alternator) during flight would the engine stop working

the avionics equipment in the aircraft might fail but the engine would keep running because it is powered directly by the dual magnetos

Why do we have to keep adjusting the fuel/air mixture as we climb?

decreases air density so we need to decrease the fuel

what causes carburetor ice?

fuel vaporization and decreasing air pressure in the venturi. as pressure decreases so does temperature

how would we know we have carburetor ice?

a loss in RPM (engine revelations per minute) then a gradual increase as the ice melts.

what is the risk of operating an engine with excessively high oil temperature?

may use more oil, lose power, or may result in permanent engine damage.

Who is responsible for checking the engine oil level and during preflight to determine the aircraft is safe for flight?

the PIC

Detonation

the unburned fuel/air charge explodes due to pressure instead of burning normally with spark ignition. Grade of fuel used in an aircraft engine is lower than specified for the engine

Pre-ignition

The uncontrolled firing of the fuel/air charge in advance of normal spark ignition is known as a 'hot spot'

Required Documents with the pilot

pilot certificate of appropriate grade, medical certificate of appropriate grade, government issued photo ID

Medical certificate length

is valid through the last day of the month regardless of the day the physical exam was given

1st Class Medical

over 40, expires after 6 calendar months

under 40, expires after 12 calendar months

Needed if exercising privileges of an airline transport pilot certificate

2nd Class medical

needed if exercising the privileges of a commercial pilot certificate

privileges valid for 12 calendar months

3rd Class medical

needed for student, recreational, private, or flight instructor certificate

under 40: valid for 60 calendar mothers (5 years)

40 and older: valid for 24 calendar months

Safety Belts

Crew: during takeoff, landing, and while enroute, each required crew member shall keep their seatbelt fastened while at their station. During takeoff and landing, this includes wearing a shoulder harness (if installed) unless it interferes with required duties

91.15 dropping objects

PIC may not allow any object to be dropped from an aircraft in flight that creates a hazard to people or property. This does not prohibit the dropping of an object if reasonable precautions are taken to avoid injury or damage to persons or property on the surface

Right of way Rules: Overtaking

the aircraft being overtaken has the right of way. the overtaking aircraft shall alter course to the right when passing

right when passing: Landing

aircraft on final approach have right of way over other aircraft in flight or on the surface (cannot use this rule to force an aircraft off the runway surface)

aircraft approaching an airport to land: lower aircraft has the right of way (but it shall not take advantage of this rule to cut in front of or to overtake another)

VFR cruising altitude

between 3,000 AGL and 18,000 MSL you must fly these specific altitudes while in VFR cruising flight (based on the aircraft's magnetic course)

Magnetic Track above 3000 AGL (VFR crushing altitudes)

VFR odd 1000s+500 from 0degrees to 179

VFR even 1000s+500 from 180degrees to 359

Why listen to land and hold short?

it can greatly increase efficiency of traffic flow at airports

why decline a land and hold short?

safety, PIC has final authority

Land and Hold Short Operations (LAHSO)

ATC tool to increase airport capacity; pilot must accept; no student solo pilots may participate.

How does the wind tetrahedron work?

the tiny point points the way you should land and take off because the tip faces the wind

When taxing in winds remember:

Turn into a headwind and dive away from a tailwind

Thumbs up it's up

Dive away=elevator down

If you have a headwind taxing what do you do?

Wind coming from the right= up aileron on right side and neutral elevator

Wind coming from the left= up aileron on left side and neutral elevator

If you have a tailwind while taxing what do you do?

Wind from left back= down aileron on left wind and down elevator

Wind from right back= down aileron on right wing and down elevator

After what kind of incident do you need to inform NTSB immediately?

Flight control system malfunction, inability for crew member to preform their duties due to injury or illness, failure of any internal turbine engine component that results in debris escaping somewhere other than in the exhaust path, inflight fire, Mid-air collision, damage to property (other than aircraft) exceeding $25,000

Visual Approach Slope Indicator (VASI)

A visual aid of lights arranged to provide descent guidance information during the approach to the runway. A pilot on the correct glideslope will see red lights over white lights.

VASI red over white

on glide path (you're all right)

VASI white over white

Too high (you'll be flying all night)

VASI red over red

Too low (you're dead)
