What is braking action advisories?
BRAKING ACTION ADVISORIES− When tower controllers receive runway braking action reports which include the terms “medium,” “poor,” or “nil,” or whenever weather conditions are conducive to deteriorating or rapidly changing runway braking conditions, the tower will include on the ATIS broadcast the statement, “Braking …
What is included in ATIS?
In the US, ATIS will include (in this order): the airport or facility name; a phonetic letter code; time of the latest weather observation in UTC time; weather information consisting of wind direction and velocity, visibility, obstructions to vision, sky condition, temperature, dew point, altimeter setting, density …
What is a mu reading?
According to the AIM, MU (friction) values range from 0 to 100, with 100 being the best friction and braking action you can get. When there are frozen contaminants on the runway, an MU value of 40 or less means that aircraft braking performance deteriorates, and directional control becomes less responsive.
What is braking action Aviation?
Braking action in aviation is a description of how easily an aircraft can stop after landing on a runway. Either pilots or airport management can report the braking action according to the Federal Aviation Administration of the United States.
What is Rcam aviation?
The FAA is implementing the use of the Runway Condition Assessment Matrix (RCAM) which will be used by airport operators to perform assessments of runway conditions and by pilots to interpret reported runway conditions. This is typically the runway end primarily in use.
What is the difference between Metar and ATIS?
The ATIS has more information than just the METAR, so while the ceiling, wind and temperature information will look the same, the ATIS will include active runways, approaches and other important information the METAR omits. Unfortunately, not all airports have a digital ATIS phone number.
What frequency is Ctaf?
126.7 MHz
The most common CTAF frequency is 126.7 MHz at non-towered aerodromes, except for when two CTAF airports are near each other. Aerodromes using CTAF outside tower hours typically nominate a frequency that is used during tower hours.
What is ATIS Aviation?
Definition. The automatic provision of current, routine information to arriving and departing aircraft throughout 24 hrs or a specified portion thereof: Data link-automatic terminal information service (D-ATIS).
What is the purpose of ATIS?
Use the ATIS, where available, to provide advance noncontrol airport/terminal area and meteorological information to aircraft. Identify each ATIS message by a phonetic letter code word at both the beginning and the end of the message. Automated systems will have the phonetic letter code automatically appended.
What are the four types of braking action reports?
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.
What is runway condition code?
It comprises the evaluation of a runway and the assignment of a Runway Condition Code (RWYCC) ranging from 0 for a very slippery surface to 6 for a dry surface. This code is complemented by a description of the surface contaminant, based upon its type, depth and coverage, for each third of the runway.
What do I need to know about braking action advisories?
Braking Action advisories are in effect.” Advise aircraft of changes to the ATIS code by broadcasting the change on all appropriate frequencies. The broadcast must include changes to pertinent operational information, when known, that necessitated the ATIS change. “Attention all aircraft, information ALPHA current.”
When to put runway braking action in effect?
When tower controllers have received runway braking action reports which include the terms poor or nil, or whenever weather conditions are conducive to deteriorating or rapidly changing runway braking conditions, the tower will include on the ATIS broadcast the statement, “BRAKING ACTION ADVISORIES ARE IN EFFECT.”
How is the quality of braking action described?
[Aeronautical Information Manual§4−3−8] When available, ATC furnishes pilots the quality of braking action received from pilots or airport management. The quality of braking action is described by the terms “good,” “fair,” “poor,” and “nil,” or a combination of these terms.
What do pilots do when they are unable to receive the ATIS?
When a pilot is unable to receive the ATIS, issue the current weather, runway in use, approach/departure information, pertinent NOTAMs, and airport conditions.
