How is braking action reported?
Either pilots or airport management can report the braking action according to the Federal Aviation Administration of the United States. When reporting braking action, any of the following terms may be used: Good; Medium; Poor; Nil – bad or no braking action.
How do I decode a METAR report?
Decoding a METAR
- PHNL = the airfield, Honolulu’s Daniel K.
- 250953Z = the date and time of the report.
- 05007G17KT = the wind conditions.
- 10SM = visibility.
- FEW024 / FEW040 = cloud cover.
- 27/19 = the temperature and dewpoint.
- A3001 = the atmospheric pressure, a.k.a. altimeter setting.
What is fair braking action?
GOOD: No degradation of braking action. FAIR: Somewhat degraded braking conditions. POOR: Very degraded braking conditions. NIL: No braking action. Practical Application.
What does VV003 mean in a METAR?
The following can also appear in the cloud section of a METAR, though these are more commonly found in the remarks section (later): TCU: Towering Cumulus CB: Cumulonimbus VV###: Vertical visibility (for an obscured sky cover). VV003 = Vertical visibility of only 300 ft.
What does RCR mean aviation?
The Runway Condition Report (RCR)
What is RCR in aviation?
Issue the runway surface condition and/or the Runway Condition Reading (RCR), if provided, to all USAF and ANG aircraft.
What is VV in aviation?
VV. Vertical Visibility (Indefinite Ceiling) WS. Wind shear (In TAFs, low level and not associated with convective activity)
What does 8000 mean in a TAF?
GROUP 4: Visibility, Weather, and Obstructions to Vision:
| Meters | SM |
|---|---|
| 6,400 | 4 |
| 8,000 | 5 |
| 9,600 | 6 |
| 11,200 | 7 |
Who will primarily use the Rcam to assess runway conditions?
The airport operator will use the RCAM to assess paved runway surfaces, report contaminants present, and through the assistance of the Federal NOTAM System, determine the numerical Runway Condition Codes (RwyCC) based on the RCAM.
What does speci mean in a METAR?
A SPECI is a special report of meteorological conditions, issued when one or more elements meet specified criteria significant to aviation. SPECI is also used to identify reports of observations recorded ten minutes following an improvement (in visibility, weather or cloud) to above SPECI conditions. Location.
What does VV001 mean?
If the sky above the aerodrome is obscured and cloud coverage cannot be easily determined, (VV) Vertical Visibility in hundreds of feet is provided, e.g. VV001 would mean the vertical visibility is 100 feet. Temperature / Dewpoint.
Is a wet runway contaminated?
For purposes of condition reporting and airplane performance, a runway is considered contaminated when more than 25 percent of the runway surface area (within the reported length and the width being used) is covered by frost, ice, and any depth of snow, slush, or water.
Can a braking action be appended to a METAR report?
Although a braking action may be appended onto a METAR the time of the report will be found in the NOTAMs and will most likely not be the time of the METAR issued. The reference to good in the braking will relate to the time it was issued in the notam.
What are the braking action codes for rwycc?
The runway braking action codes RwyCC system uses 7 numbers, from zero to six. As you would imagine, zero is bad, while six is good. The numbers are issued for each third of the runway: touchdown, midpoint and rollout, hence the 5/3/2 format.
Do you report “nil” braking?
Speaking of “NIL” braking, you should not be hearing that report anymore. The FAA says it is no longer acceptable for an airport to report a braking action of “NIL” because “NIL” conditions on any surface – runway OR taxiway – require closure of that surface until the braking action is at least poor or better.
What information is included in a metmetar report?
METAR reports may include runway reports which contain information about snow/water coverage and friction coefficient. A runway report consists of eight digits in five groups ( RRRRERCReReRBRBR ) with the following interpretation: Runway designator.
