Why can the FAA tell me where to fly me UAS? - correct answer ✔✔1) Federal Law
2) Safety and Separation
Safety and Separation two types: - correct answer ✔✔1) Instrument Flight Rules
2) Visual Flight rules
Instrument flight rules - correct answer ✔✔Weather or other training conditions are such that the
aircraft is being flown by using instruments only (without looking outside). Although there are lots of
other requirements and technology involved, for sUAS operators the important thing to know is that
pilots of aircraft (even at low altitude) are not always looking out the cockpit windows.
Visual Flight Rules - correct answer ✔✔Weather conditions allow piloted aircraft to fly with very little or
no air traffic control assistance by looking outside. For sUAS operators, this is important because piloted
aircraft following Visual Flight Rules can fly just about anywhere, even into restricted airspace (and often
do). It is also important because VFR piloted aircraft can fly as low as 500 ft. above ground level.
Where can't I fly my SUAS in the NAS? - correct answer ✔✔- Not above 400ft
- Not in Unauthorized airspace
- Not over populated
Where can I fly my SUAS in the NAS? - correct answer ✔✔1) Below 400ft AGL
2) Within Line of Sight (LOS)
3) UAS Test sites
4) Within Unrestricted Airspace
, Six types of airspace - correct answer ✔✔Class A - Above 18,000' MSL (Mean Sea Level)
Class B - Located above large, busy airports and arranged like an upside down wedding cake, typically
with three layers. The layers form a stepped inverted cone. Class B airspace only exists over "Busy" or
"Big" airports.
Class C - Located above airports with active Approach and Departure control, but not busy enough for
Class B designation. Also arranged as a two tier upside down wedding cake. Class C airspace exists over
"City" airports.
Class D - Located in a cylinder above smaller airports that still maintain an active air traffic control tower.
Class E - Class E is the 'filler' airspace and extends from 1,200' AGL to the bottom of Class A airspace at
18,000' MSL.
Class G - This is what is called 'uncontrolled' airspace, and extends from the surface to 700' AGL or 1,200'
AGL.
Airspace Sectional Chart Markings: - correct answer ✔✔Class A: No typically marked
Class B: Marked by Thick Blue Lines at Perimeter
Class C: Marked by Thick Magenta Lines at Perimeter
Class D: Marked by Dotted Blue Line
Class E: When the Floor is 1,200 not marked Altutude. When the Floor is at 700 marked by faded
margenta border.
Class G: Not typically marked
Athmosphere basics: - correct answer ✔✔- As altitude increases, the atmospheric/Barometric pressure
decreases
- As altitude increases, temperature decreases
Standard pressure at sea level? - correct answer ✔✔- 29.92 inches of mercury
Lapse rate: - correct answer ✔✔- this is the standard change is temperature as you increase altutide
- Is the Rate this temperature change occurs
Average laspe rate: 2 dgress C per 1000 of altitude
