1. How can a pilot receive updated weather information in-flight?
(AIM 7-1-5)
|
En Route Flight Advisory Service (EFAS)
c. Contact flight watch by useing the name of the ARTCC facility identification serving the area of your location, followed by your aircraft identification, and the name of the nearest VOR to your position. The specialist needs to know this approximate location to select the most appropriate transmitter/receiver outlet for communications coverage.
d. Charts depicting the location of the flight watch control stations (parent facility) and the outlets they use are contained int he A/FD. If you do not know in which flight watch area you are flying, initiate contact by using the words "Flight Watch," your aircraft ID, and the name of the nearest VOR. THe facility will respond using the name of the flight watch facility.
[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.
In conjunction with this service, 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' AGL to 17,000' MSL on a common frequency of 122.0 MHz.
It is also known as "Flight Watch."] |

5. What is a microburst? When and where are they most likely to occur?
(AIM 7-1-26) |
a. Microbursts are small scale intense downdrafts which, on reaching the surface, spread outward in all directions from the downdraft center.
This causes the presence of both vertical and horizontal wind shears that can be extremely hazardous to all types and categories of aircraft, especially at low altitudes.
Due to their small size, short life span, and the fact that they can occur over areas without surface precipitation, microbursts are not easily detectable using conventional weather radar or wind shear alert systems.
b. Parent clouds producing microburst activity can be any of the low or middle layer convective cloud types. However, microbursts commonly occur within the heavy rain portion of thunderstorms, and in much weaker, benign appearing convective cells that have little or no precipitation reaching the ground.
Microbursts can be found almost anywhere that there is convective activity. -heavy rain associated with a thunderstorm -light rain in benign appearing virga
Can last 15 minutes to an hour.
e. Microburst wind shear may create a severe hazard for aircraft within 1,000ft of the ground, particularly during landing and takeoff. |

6. What is a sea breeze, and why does it occur?
(AC 00-6) |
A coastal breeze blowing from sea to land caused by the temperature difference when the land surface is warmer than the sea surface.
Sea breeze usually occurs during the day. |

Additional Study Questions
7. What is a mountain wave?
(AC 00-6) |
Mountain waves occur when air is being blown over a mountain range or even the ridge of a sharp bluff area.
As the air hits the upwind side of the range, it starts to climb, thus creating what is generally smooth updraft which turns into a turbulent downdraft as the air passes the crest of the ridge.
From this point, for many miles downwind, there will be a series of downdrafts and updrafts.
All it takes to form a mountain wave is wind blowing across the range at 15 KTS or more at an intersection angle of 30 degrees or more. |
