STD
2005/06/07
AIRCRAFT_TURBULENCE-
_INTENSITY
EXTREME Turbulence in which the <AIRCRAFT> is violently tossed about, and is practically impossible to control; extreme. Extreme turbulence may cause structural damage to the <AIRCRAFT>. 8 IR [AIM, Table 7-1-7:Extreme]  
STD
2005/06/07
AIRCRAFT_TURBULENCE-
_INTENSITY
LIGHT Turbulence that momentarily causes slight, erratic changes in <AIRCRAFT> altitude and/or attitude (pitch, roll, yaw) or turbulence that causes slight, rapid and somewhat rhythmic bumpiness without appreciable changes in <AIRCRAFT> altitude or attitude; light. 2 IR [AIM, Table 7-1-7:Light] [JMCDM, "AIRCRAFT-TURBULENCE-OBSERVATION frequency code":5]
STD
2005/06/07
AIRCRAFT_TURBULENCE-
_INTENSITY
LIGHT_TO_MODERATE Between <<<LIGHT>>> and <<<MODERATE>>>. 3 IR [JMCDM, "AIRCRAFT-TURBULENCE-OBSERVATION intensity code":2]  
STD
2005/06/07
AIRCRAFT_TURBULENCE-
_INTENSITY
MODERATE Turbulence that causes changes in <AIRCRAFT> altitude and/or attitude occurs but the <AIRCRAFT> remains in positive control at all times despite variations in indicated airspeed, or turbulence that is similar to <<<LIGHT>>> but of greater intensity, causing rapid bumps or jolts without appreciable changes in <AIRCRAFT> altitude or attitude; moderate. 4 IR [AIM, Table 7-1-7:Moderate] [JMCDM, "AIRCRAFT-TURBULENCE-OBSERVATION intensity code":3 and "ATMOSPHERIC-TURBULENCE-ANALYSIS-FORECAST turbulence intensity code":2]
STD
2005/06/07
AIRCRAFT_TURBULENCE-
_INTENSITY
MODERATE_TO_SEVERE Between <<<MODERATE>>> and <<<SEVERE>>>. 5 IR [JMCDM, "AIRCRAFT-TURBULENCE-OBSERVATION intensity code":4]  
STD
2005/06/07
AIRCRAFT_TURBULENCE-
_INTENSITY
NO_TURBULENCE No turbulence. 1 IR [JMCDM, "ATMOSPHERIC-TURBULENCE-ANALYSIS-FORECAST turbulence intensity code":0]  
STD
2005/06/07
AIRCRAFT_TURBULENCE-
_INTENSITY
SEVERE Turbulence that causes large, abrupt changes in <AIRCRAFT> altitude and/or attitude, usually with large variations in indicated airspeed and possibly with momentary loss of control; severe. 6 IR [AIM, Table 7-1-7:Severe]  
STD
2005/06/07
AIRCRAFT_TURBULENCE-
_INTENSITY
SEVERE_TO_EXTREME Between <<<SEVERE>>> and <<<EXTREME>>>. 7 IR [JMCDM, "AIRCRAFT-TURBULENCE-OBSERVATION intensity code":6]  

Group membership:

In addition to the status and date information for each entry, a colour coding scheme highlights the database holding to which an entry belongs. The following highlight colours are used:

  • white - the entry is in the standard
  • yellow - the entry has been added to the register
  • pink - the entry has been submitted for inclusion in the register, but it is not approved
  • cyan - a deprecated entry that was originally either in the standard or was added to the register, but has since been deprecated

The following icons are used to identify items that have figures, modifications and/or clarification notes:

  • F n - has Figures and, if more than one figure, n figures
  • M - has Modifications
  • C - has Clarifications
