2016年1月20日 · For example, shown here is an urgent pilot weather report for severe turbulence at 8,000 ft MSL in the Florida Panhandle. Above and beyond the different turbulence and icing symbols and to further attract your attention, urgent pilot reports in ForeFlight contain a red badge in the upper-right corner like the turbulence report shown above.

2024年9月3日 · In extreme turbulence, your aircraft is violently tossed about and practically impossible to control. Extreme turbulence can cause structural damage or structural failure. When you report turbulence to ATC, it's important to include the turbulence frequency as well. Here's what you should tell them. Occasional: Less than 1/3 of the time.

Severe turbulence. Turbulence that causes large, abrupt changes in altitude and/or attitude. It usually causes large variations in indicated airspeed. Aircraft may be momentarily out of control. Extreme turbulence. Turbulence in which the aircraft is violently tossed about and is practically impossible to control. It may cause structural damage.

The most intense turbulence is usually located at low-levels, leeward of the mountains in or near the rotor cloud, if present Mountain waves may be denoted by mountain wave clouds - Cirrocumulus Standing Lenticular (CCSL) - Altocumulus Standing Lenticular (ACSL) - Rotor clouds (often associated with the most intense turbulence) 2.

Mountain waves frequently produce severe to extreme turbulence. Clear Air Turbulence (CAT) is a higher altitude (20,000 to 50,000 feet) turbulence mostly associated with jet streams. The turbulence will be more severe with curved jets and in mountainous areas, particularly when mountain waves are present.

Low altitude data, previously found within the Helicopter Emergency Medical Services (HEMS) tool, is available to aid the Helicopter Air Ambulance (HAA) community and other low altitude flights. Built with modern geospatial information tools, users can pan and zoom to focus on areas of greatest interest.

Turbulence is a subjective measure, and its measurement is somewhat depending on the size of the aircraft in which it is felt and the aircraft's speed. Turbulence that momentarily causes slight, erratic changes in altitude and/or attitude (pitch, roll, yaw). Report as Light Turbulence.

Extreme turbulence is capable of causing structural damage and resulting directly in prolonged, possibly terminal, loss of control of the aircraft. In-flight turbulence assessment is essentially subjective.

2024年9月3日 · Severe and Extreme Turbulence: Turbulence can significantly impact the safety and comfort of your flight. In PIREPs, severe or extreme turbulence may be marked as “UUA,” indicating urgent reports. These turbulence types can include clear air turbulence, which is particularly challenging to predict and detect.

METARs are displayed as blue-tinted circles, with the standard Aviation Flight Category colors and Cloud Coverage symbols. The Cloud Coverage displayed is based on the greatest coverage, regardless of altitude. SKC: Open Circle icon indicates clear sky (no cloud cover).
