What causes all weather on Earth?
Uneven heating of the Earth's surface
What is the acronym used for illusions in IFR?
ICEFLAGS
What instruments are a part of the pitot static system?
ASI, VSI, OAT, and ALT
What are 3 ground based navigation systems that are available for us to use?
VOR, LOC, DME, LDA, SDF, NDB, and WAAS/LAAS.
What's the main difference between a precision approach and a non-precision approach?
What temperature and pressure is a standard atmosphere?
15°C/59°F & 29.92/1013.2
When is oxygen required while flying?
12,500- after 30 minutes
14,000- Required crew must be on it
15,000- must be offered to passengers
What two LRU's give use our gyro instruments and pitot static instruments?
AHRS and ADC
How does WAAS work?
Satellites send their signal to wide area reference stations then to master stations (3) then to GB uplink stations then to geostationary satellites back to our airplane.
What's the difference between a DA and MDA?
You make a go/no-go decision at the DA where as you stop at the MDA and continue to the MAP in order to go missed.

Outer marker, middle marker, inner marker, and back course
What's the difference between a glide slope and glide path?
Glide path is found a GPS based approaches and is generated where as a glide slope is made by a ground based system.
When can a Sigment valid for 6 hours?
During volcanic ash and hurricanes.
What 3 sensory systems do we use in aviation?
visual, vestibular, and somatosensory systems
If you pull your alternate static port, what readings will you get from your pitot static instruments?
slight higher ASI and ALT. VSI will have a temp rise then settle back to 0.
What's the difference between the signal VOR uses and the signal WAAS uses?
VOR- VHF
WAAS- UHF
How much is an approach offset from the runway to only have circling minima?
30°
How far should you avoid thunderstorms by and why?
20 miles due to hail, lightning, invisible dangers such as microbursts.
A pilot is flying at night and upon landing prop strikes. What is the illusion he most likely experienced and why does it occur?
Featureless terrain illusion or black hole illusion makes the pilot perceive they are higher than they actually are from the ground leading to them flying dangerously low approach paths.
The turn coordinator works off of what gyroscopic principal?
Gyroscopic precession
What certification does your GPS require in order to be WAAS certified?
TCO-145 or 146
What are the different types of diverse departure procedures? What are the minimum criteria you must meet in order to fly them?
Diverse departure procedure, VCOA, and DVA
