Wind shear that resulted from the strongest microbursts actually measured in the summer of 1982 Joint Airport Weather Studies (JAWS) in Denver could not have been penetrated safely if encountered below 300-500 feet of altitude by an aircraft*

From page 2... ...
Such a program should include warnings to avoid encountering wind shear if possible as well as the best advice available on piloting techniques to minimize risk when a shear is inadvertently encountered at low altitude. As part of this campaign, the FAA should revise and update its 1979 advisory circular on wind shear (AC 00-50A)
|
From page 3... ...
This effort should include field studies of low-altitude wind shear, particularly those associated with convective clouds and thunderstorms. To help in this understanding, LLWSAS data should be recorded at all sites and analyzed, and existing data from previous research programs should be reexamined.

From page 4... ...
The most practical and immediate solution appears to be an extensive education program to warn general aviation pilots of the hazards associated with low-altitude wind shear and to teach both avoidance and escape procedures. Finally, the committee recommends that the FAA establish an integrated and sustained program for coping with all aspects of wind shear -- meteorological, technological, operational, and educational.

on wind shear and the Airman's Infurmution Minuet (AIM) to present the latest information, including detection techniques, alerting and warning procedures, effects of wind shear on aircraft performance, and procedures for recovery from wind-shear encounters.

From page 6... ...
These radars detect rain showers, thunderstorms, and phenomena often associated with wind shear. Information from weather radars should be made available to air traffic controllers in a timely and easily understandable fashion.

From page 7... ...
10. Use of Airport Terminal Weather Radar Observations For terminal Doppler radar to be most useful to traffic controllers and pilots, a concerted effort should be devoted to developing procedures for analyzing, displaying, and using its observations.
|
From page 8... ...
In addition, the FAA should encourage operators of jet aircraft to incorporate in their manuals the operating procedures recommended in its advisory circular on wind shear. Aircraft manufacturers should recommend configuration-change sequences (gear, flaps, power, spoilers, etc.)
|
From page 9... ...
Research should include additional field observations and the construction of theoretical models over the relevant scales -- from about 1,000 feet to 10-20 miles and from minutes to hours. The existing body of data obtained by various research programs should be reexamined and augmented, at an appropriate time, by a field program in the humid southeastern United States.
