Map of fire TFR: from the Station Fire


The National Interagency Airspace Information website has a very good website where you can search for information on all TFRs by state, type (fire, laser, nuclear, presidential, and stadium). The also have links for recent, and pending TFRs as well as canceled TFRs. In addition, there is an interactive map where you can plot TFRs with options for different kinds of maps.

A note on laser TFRs (bounded by skinny bright purple circles on charts available through airspace.nifc), laser light shows require TFRs because they interfere with a pilots vision. Not good for anyone, especially someone piloting an aircraft. To the best of my knowledge there are no laser light TFRs shown on the above image. The purple lines and shapes of various widths on the above image are not laser light TFRs, but depict different kinds of airspace.

When you search for TFRs, for example by state, you are presented with a screen showing the actual NOTAM text for each TFR in that state with options to print that portion of the sectional (aeronautical chart) with the TFR plotted on the map. You can also search by type and see only the fire TFRs.

The image above shows the TFR for the Station Fire that I printed about three weeks ago. Actually, I was able to print the map to a pdf file and then used a graphics conversion program to save it is a jpeg file for posting here. The green circles on the map are stadium/sports TFRs. The area within the red polygon was the Station Fire TFR. As I mentioned in my last post, aeronautical charts take some getting used go and I am only beginning to get use to them myself. But they do mean something to pilots.

Here is a copy of the actual NOTAM, note that the number of NOTAM (9/7722) matches the number on the image (9/7792):

NOTAM : 9/7792

FDC 9/7792 ZLA CA.. FLIGHT RESTRICTIONS NORTH OF LA CANADA, CA. EFFECTIVE IMMEDIATELY UNTIL FURTHER NOTICE. PURSUANT TO 14 CFR SECTION 91.137(A)(2) TEMPORARY FLIGHT RESTRICTIONS ARE IN EFFECT WITHIN AN AREA BOUNDED BY 343137N/1181838W OR THE VAN NUYS /VNY/ VOR/DME 011 DEGREE RADIAL AT 20.2 NAUTICAL MILES THEN TO 342548N/1175006W OR THE PALMDALE /PMD/ VORTAC 122 DEGREE RADIAL AT 16.5 NAUTICAL MILES THEN TO 340811N/1175831W OR THE POMONA /POM/ VORTAC 275 DEGREE RADIAL AT 9.9 NAUTICAL MILES THEN TO 341228N/1181301W OR THE VAN NUYS /VNY/ VOR/DME 079 DEGREE RADIAL AT 13.7 NAUTICAL MILES THEN TO 342013N/1183014W OR THE VAN NUYS /VNY/ VOR/DME 340 DEGREE RADIAL AT 6.8 NAUTICAL MILES BACK TO THE ORIGINAL POINT AT AND BELOW 9000 FEET MSL TO PROVIDE A SAFE ENVIRONMENT FOR FIRE FIGHTING.

In the interest of full disclosure, I should say that I got the text of the NOTAM from the FAA website very shortly after the NOTAM expired. I showed this text and the above image to a couple of my airtanker pilot friends who said that while they would have preferred to look at the actual aeronautical chart to be certain, that the text seems to be very close to the mapped NOTAM.
