Instrument Review Flashcards
How to stay Current?
6HITS
In the last 6 months, at least six approaches, holding procedures, intercepting and tracking courses through electronic systems. can log 6HITS after six months but safety pilot, examiner, or instructor must be present. Safety pilot must have private with same category and class plane. After 12 months, must do an IPC by CFII, examiner or any other approved person, some but not all tasks can be in FTD
Privileges and Limitations
Privileges: Fly as PIC under ifr weather, file ifr flight plans, carry passengers,
Limitations: cannot be paid for flights under ifr
Proficiency vs Currency
Proficiency: how much skill you have in ifr approaches. (i.e you have 6 hits but got them five months ago and haven’t flown since weather outside is ifr all around and approach needed is ils but you are used to flying rnav approaches
Currency: faa legal requirements to fly ifr
Personal Minimums
Pilot, Aircraft, enVironment, External pressure (PAVE)
More than 15kt cross wind, clouds ovc @ 2000
Flight Review if Checkride
No
Deicing & Anti-icing
No anti-icing on plane (BEFORE FLIGHT)
Deicing: could be pitot heat, carb heat, defroster (DURING FLIGHT)
Other anti-icing
Icing boots: rubber-like boots on leading edge; when system is turned on after ice accumulates on the boots and the sensor notices the boots inflate to break/ crack the ice and it falls off. ICE REDUCES THE AMOUNT OF LIFT
Fly into icing?
NO!!! Plane is not equipped to fly into icing
High/Mid/Low Level Clouds
High: 20,000 and above CIRRUS CLOUDS
Mid: 6,500-20,000 ALTO CLOUDS
Low: surface-6,500 STRATUS and CUMULUS
What is Microburst
Intense downwash of air that may last for 15 minutes, can be associated with thunderstorms (avoid heavy rain) but can also happen at any time
Thunderstorm characteristics and Hazards
Need unstable air, lifting force, and water vapor. Three stages: Cumulus(Updrafts), Mature(Rain), Dissipating(Downdrafts)
Hazards: Microburst, Lightning, Hail, Limited visibility, strong updrafts&downdrafts, turbulence
Airmets T,Z,S
Valid for 6 hours; Tango: Moderate Turbulence, Zulu: Moderate Icing, Sierra: IFR weather and mountain obscurations
Sigmets
Valid for 4 hours; hazardous weather not associated with Thunderstorms, Dust Storms, SandStorms
Convective Sigmets
Valid for 2 hours; Convective weather hazardous to all aircraft; Severe Thunderstorms, Embedded Thunderstorms, Tornadoes, Line of Thunderstorms, Wind shear, Severe Icing and Turbulence
Weather for Alternate and weather required
123 rule
alternate required unless instrument approach is published and available and for 1 hour before to 1 hour after flight weather will be at least 2,000 ft ceiling and 3SM visibility
If alternate weather not published: Non precision: 800ft 2SM Precession: 600ft 2SM
Class E Weather
Under 10000 MSL: 3SM Clouds 1,000 above 500 below 2,000 horizontally
Types of Fog
Happens 50ft above ground when temp/dew point are same.
Advection: warm air moves over cold surface
Radiation: calm clear nights when ground rapidly cools because of release of ground heat
Upslope: moist air is forced up terrain and cooled by adiabatic cooling
Ice: temp below freezing and water vapor turns into ice crystals
Steam: cold air moves over warm surface
Types of Icing
Structural: Happens with visible moisture and surface below freezing
- Clear (Worst, Hard to see, smooth, large supercooled water droplets), Rime (rough, small supercooled water droplets), Mixed
Instrument: pitot and static
Induction: reduces the amount of air for engine intake
Intake: block engine intake
Carburetor: temperature drops in carburetor venturi
What to do if you don’t break out
GO TO ALTERNATE OR SHOOT DIFF APPROACH
Can you shoot same approach
NO
