List criteria for the origination of NOTAM concerning Hazards.
- Presence of hazards which affect air navigation (including obstacles, military exercises, displays, races, unmanned aircraft)
- Erecting, removal or changes to significant obstacles to air navigation on take off/climb, missed approach, approach areas and runway strip.
- Presence or removal or significant change in hazardous conditions due to snow, slush, ice or water or other contaminants in the movement area.
- Operationally significant changes in volcanic activity, the location, date and time of volcanic eruptions and the existence, density and extent of volcanic ash cloud, including direction of movement, flight levels and routes or portions of routes which could be affected.
- Release into the atmosphere of radioactive materials or toxic chemicals following a nuclear or chemical incident, the flight levels and routes or portions thereof which could be affected and the direction of movement
What does the response NIL CURRENT mean with respect to other than Restricted or Danger Area PRD NOTAM?
No information currently held for that location.
What does the response NIL CURRENT mean with respect to Restricted or Danger Area PRD NOTAM?
No change to the status of the area as defined in the documents
Are pilots required to pass details of hazardous weather to ATS for distribution?
Yes, the PIC, both inside and outside controlled airspace, must advise ATS promptly of any hazardous weather encountered or observed (either visually or by radar).
Whenever practicable, those observations should include as much detail as possible, including location and severity.
What intensities of windshear should be reported?
- Light - shear causing minor excursions from flight path and/or airspeed.
