What is "EFAS"? (AIM 7-1-5) - Correct Answer ✔️✔️Enroute Flight Advisory
Service (EFAS) is a service specifically designed to provide enroute aircraft with
timely and meaningful weather advisories pertinent to the type of flight intended,
route of flight, and altitude. EFAS is also a central collection and distribution point
for pilot-reported weather information (PIREPs). EFAS provides communications
capabilities for aircraft flying at 5,000 feet above ground level to 17,500 feet MSL
on a common frequency of 122.0 MHz. It is also known as "Flight Watch." Discrete
EFAS frequencies have been established to ensure communications coverage
from 18,000 through 45,000 feet MSL, serving in each specific ARTCC area. These
discrete frequencies may be used below 18,000 feet when coverage permits
reliable communication.
,What is "HIWAS"? (AIM 7-1-10) - Correct Answer ✔️✔️Hazardous In-flight
Weather Advisory Service (HI WAS) is a continuous broadcast of in-flight weather
advisories including summarized Aviation Weather Warnings, SIGMETs,
Convective SIGMETs, Center Weather Advisories, AIRMETs, and urgent PIREPs. HI
WAS is an additional source of hazardous weather information which makes this
data available on a continuous basis.
What is a METAR? - Correct Answer ✔️✔️The aviation routine weather
report (METAR) is the weather observer's interpretation of the weather
conditions at a given site and time. It is used by the aviation community and the
National Weather Service (NWS) to determine the flying category (VFR. MVFR. or
IFR) of the airport, as well as produce the Terminal Aerodrome Forecast (TAF).
Describe several types of Automated Surface Observations now available. -
Correct Answer ✔️✔️ASOS—Automated Surface Observing System; the
primary U.S. surface weather observing system; up to 993 systems installed
throughout the U.S., providing minute-by-minute observations, METARs and
other aviation weather information; transmitted over a discrete VHF radio
frequency or the voice portion of a local NAVAID. An ASOS/AWOS report without
human intervention will contain only that weather data capable of being reported
, automatically. The modifier for this METAR report is "AUTO." When an observer
augments or backs-up an ASOS/AWOS site, the "AUTO" modifier disappears.
AWOS— Automated Weather Observation System, installed by the FAA at
selected airports around the country. This system consists of automated reports
of ceiling/sky conditions, visibility, temperature, dew point, wind
direction/speeds/gusts, altimeter setting, and if certain conditions are met,
automated remarks containing density altitude, variable visibility and variable
wind direction. Automated observations are broadcast on ground-to-air radio and
made available on a telephone answering device.
What are PIREPs (UA), and where are they usually found? - Correct Answer ✔
️✔️An abbreviation for "pilot weather reports." A report of meteorological
phenomena encountered by aircraft in flight. Required elements for all PIREPs are
type of report, location, time, flight level, aircraft type, and at least one weather
element encountered. All altitude references are MSL unless otherwise noted.
Distance for visibility is in SM; all other distances are in NM. Time is in UTC.
What are Radar Weather Reports (SDs)? - Correct Answer ✔️✔️General
areas of precipitation, including rain, snow, and thunderstorms, can be observed
by radar. The radar weather report (SD) includes the type, intensity, and location
