POH/AFM, FAR AIM, Aircraft Inspection

POH/AFM
-AFM-aircraft specific
-POH-general to make an model-not individual aircraft
-both have the same 9 sections
1-general
2-limitations
3-emergency procedures
4-normal procedures
5-performance
6-weight and balance/equipment list
7-systems description
8-handling, services, maintenance
9-supplements
-Registration must be renewed every 3 years and kept in aircraft at all times -airworthiness certificate is issued after manufacture of the aircraft-valid if you keep up with all maintenance and inspections

Documents:
A- airworthiness
R- registration
R- radio station license(FCC)
O- operating limitations(Manuals/placards)
W- weight and balance data

AIM-
-strong recommendations from FAA
-Do not have to be followed, but should be
-Published by ASA, NOT the FAA

Annual inspection
-and reciprocating engine, or single engine turbojet/turbo prop less than 12,500lbs -in order to fly, must have annual within past 12 calendar months
-unless a ferry permit is issued
100 Hr inspection
-under 12,500lbs(except turbojet)
-used for hire or flight training
-A&P mechanic
-annual can cover 100hr, but 100hr doesn’t cover annual

-Transponder must be checked within preceding 24 cal. months -ELT must be checked within preceding 12 cal. months
-Altimeter must be inspected within preceding 24 cal. months

*****Air is heated unevenly by incoming solar radiation

*****Heated air rises and moves
____
Troposphere
Tropopause
Stratosphere
Stratopause
Mesosphere
Mesopause
Thermosphere
_____

As air rises it cools by 2C per 1000’

Coriolis Force- created by the rotation of
-Deflects air to the right in northern hemisphere causing to follow a curved path
-Deflection is greatest at the poles
-Differs with speed
Three cell circulation results in 3 flow patterns in northern hemisphere

9-26-13
-Stable atmosphere=calm flight=good
-unstable atmosphere=turbulent

-when warm air ends up under cold air, you get areas of ascending and descending air=Turbulence

Stable Day:
-stratiform clouds and fog
-continuous precipitation
-smooth air
-haze

Unstable day:
-cumuliform clouds
-showery precipitation
-rough air
-good visibility, except in blowing obstructions

Adiabatic heating and cooling
-rising air expands and cools
-due to increase in air pressure as altitude increases

Lapse rate
-2C or 3.5F per 1000’
-dry is 3C or 5.4F per 1000’
-moist is 1.1-2.8C or 2-5F per 1000’

Temperature inversions
-when temperature of the air rises with altitude, a temperature inversions exists -the air at the top acts as a lid for weather
-if relative humidity is high, it can contribute to the formation of clouds, fog, haze, or smoke, resulting in diminished visibility

Humidity
-the amount of moisture the air can hold
-ex. if relative humidity is 65% the air is holding 65% of the air it can hold
When air cools down too much, and it cant hold all the water anymore, moisture is formed- clouds, haze, fog

when dew point and temp are within 2 degrees of each other- fog, haze, clouds, etc

dew point- decreases at 1F per 1000’
convergence of temp and dew point is 4.4F per 1000’

10-1-13
Virga- rain that does not reach the ground before it evaporates -rain falls, evaporates, taking heat, causing down drafts

Fog- cloud that starts 50 above the surface
Radiation fog- occurs when ground cools rapily, and...
