Block 3 Part 1
This type of airspace only approves separation from IFR to IFR aircraft, and VFR aircraft to IFR aircraft and has a ceiling of 4,000 feet
Class C
A (T) depicted next to the facility name means this
The facility is a Terminal class NAVAID
Takeoff and landing
The difference between SKC and CLR
SKC is done by manual observation, CLR is automated and is said as "clear below 1-2 thousand"
This causes the lift necessary for precipitation formation
Fronts and converging winds
A time zone is established for this many degrees of longitude
15 degrees
This is the lowest published altitude between radio fixes that assures acceptable navigation signal coverage and meets obstacle clearnace requirements between those fixes
Minimum En Route Altitude (MEA)
A headwind can become a crosswind or tailwind when this happens
This is an Aviation Routine Weather Report
METAR
Low level wind shear is a change of winds by this speed and below this altitude
10 knots, 2,000 feet
Green and blue colors for airports on an En Route chart mean that those airports have this
Instrument Approach Procedure
On an En Route Low altitude chart, all airspace 14,500 and above is this class of airspace
This is where wind travels above mountains and develop into severe turbulence
Mountain Waves
These 2 letters are used to indicate that a weather phenomina is within 5 and 10 SM of the point of observation, but not the station.
VC
When what is greater than 0, the air is unsaturated.
Temperature Dew Point Spread
In a communication box, a frequency that is underlined means this
Pilots cannot receive transmissions from a Flight Service Station, but they can receive recorded broadcasts
Obstruction clearance but NO NAVAID communications is ensured by what
Off Route Obstruction Clearance Altitude (OROCA)
The 3 types of structural icing
Rime, Clear Ice, and Mixed Ice
These 4 letters indicate weather phenomena beyond 10 SM of the point of observation
DSNT
Each meaning in this acronym 55TWITSVW
When ceilings are at or below 5,000, when visibility is 5 miles or less, thunderstorms, windshear, icing, turbulence, sulfur gas, volcanic activity, when breaking action advisories are in affect
A shadowed heavy-lined communication box indicates this
A FSS is associated with the NAVAID
The 2 types of SIDs
Pilot NAV SID and Vector SID
Updrafts with 3,000 feet per minute are found at this stage in a thunderstorm cell
Towering Cumulus Stage
During an observation period, a variable ceiling is a rapidly decreasing and increasing ceiling of less than how many feet?
3,000
