Thrust Instrument static port blockages

Just static port is blocked

altimeter freezes, VSI shows zero

if ram, drain and static are blocked

ASI and Altimeter freeze. VSI zero

What kind of aneroid wafers do we have?

3, set to 29.92

airspeed guage uses what

ram and static (ram is from pitot tube)

where is the ram air?

front of pitot mast

where is static air?

not the front (the side of pitot mast)

where is the drain air?

the back of the pitot mast

bonus: clouds for METARS are given in AGL or MSL

AGL

Pitot static blocked

airspeed — zero

alt and vsi — normal

Blocked pitot tube and drain hole, open static

airspeed—acts like altimeter

alt and vsi — normal

blocked static, open pitot (ram)

airspeed—reversed (low in climb, high in descent)

altimeter—frozen

VSI—zero (calibrated leak)

Using alt air

airspeed and altimeter stay slightly higher

VSI shows momentary climb

bonus: what’s feathering a prop?

in multi, when you use throttle to move the prop just a teeny bit to produce least amount of drag

Break the VSI in a six pack

airspeed and alt stay slightly higher

VSI reverses (because air from drain hole is coming into cabin so it’s reversed)

VSI diaphragm expands typically in a climb or descent?

descent (and shrinks in a climb)

When do you break VSI?

if static port is blocked

when the airspeed diaphragm is surrounded by higher pressure (squeezed), is it low or high?

low

why does plane have lower pressure?

because crack and crevices act like a venturi and suck the air out, because as it gets narrower, velocity increases, and high seeks low

RAIM

receiver autonomous integrity monitoring system. 4 for 3d, 3 for 2d, fault detection and exclusion add one and two, baro-aided GPS subtract one from total

4 parts of an ILS

1. glideslope

2. localizer

3. marker beacons (football) (3 total, outer flashing blue in plane, 4-7 miles out, middle flashes amber, last flashes white)

4. approach lights (rabbits)

glideslope gives you what kind of guidance

vertical only

To log simulated approach, you have to

Descend to DA or MDA

To log an actual approach

Beginning to final approach fix or radar vectored
