New VOR/DME at Senai Airport

New VOR/DME in Johor

(Update, 9 September 2012: Corrected Lane Delta, added JB NDB data, Moved Ayer Hitam and Renggam reporting points a bit, training area North of Gunung Pulai is now West of the North South highway)

Effective 23 August 2012, DCA Malaysia will commission a new DVOR/DME at Senai airport. Currently the DVOR/DME of Senai airport is about 5 nm off the threshold of runway 16 on a bearing of 150° (i.e. you have to set course 150° from the DVOR location to reach the threshold). The new DVOR station will be closer to the threshold (1000m) and also gets a new frequency, which will be 112.5 Mhz (Ch. 72 x). Setting up a new DVOR station requires a rerouting of airways and relocation of holding areas and reporting points. For us VFR pilots this is only of marginal interest. However, the DCA also made changes to VFR lanes and the TMA, so take note. The changes are detailed in the AIP Supplement 09/2012 dated 14 June 2012. All changes are included in the new version of my “aeronautical chart of Johor”, which you can download here.

The VFR lane Charlie does not go from Kota Tinggi straight to East of JB Airfield anymore. Instead it is rerouted via South of Kg Semangar, to make sure aircraft stay clear of Danger Area 231. For more details on that have a look at my earlier post on flying to Mersing via Kota Tinggi.  Lane Delta is also routed around the danger areas with a new reporting point “East of Kampung Sungai Tiram”.

The Eastern border of the JB TMA used to go through Kota Tinggi. It is now further West and goes through restricted area 229, which means that VFR lane Charlie (from JB Town East to Kota Tinggi) is now outside the TMA. On the Western border of the TMA not much has changed. It seems to go a little further North of Simpang Renggam than it previously did.

In case you cannot remember what a VOR is: VOR stands for VHF Omnidirectional Radio (Range). The VOR is a navigational aid that allows aircraft equipped with a receiver to measure on which radial from the VOR station the aircraft is located. The DME (Distance Measuring Equipment) on the other hand tells the pilot how far from the station the aircraft is positioned.

Better Scale

Johor Airspace Map

I have updated my “chart” and trimmed it down to A4.  I have also attempted to scale it properly at 1:500,000 (i.e. the Sectional Chart scale).  The actual scale of the printed map depends very much on the printer.  The idea is to print the map on A4 without any resizing.  On my Macbook Pro it works very well with paper size A4 and a scale of 100% (in the printer dialog).

BTW: I have created these maps with Inkscape using an old TPC chart and a couple of other free resources from the Internet.  The maps are available in the source format (SVG), which can be opened with Inkscape and other vector graphic programs.  The other formats are in bitmap formats (JPEG, PNG and PDF) and cannot be edited in the sense that elements of the charts are just bitmaps and cannot be changed in shape etc.

The maps can be downloaded here.

My Own Chart

Map of Johor Airspace

A while ago I wrote about the regrettable lack of aeronautic charts for the Malaysian airspace and I half-jokingly remarked that one could draw their own charts. At about the same time I was flying with a friend West of Gunung Pulai, which is one of the training areas at Senai Airport and realized that ATC and pilots do not necessarily agree on the exact borders of the three training areas.

To help with the situation a bit, I actually sat down last weekend and learned to use Inkscape while drawing a map of the airspace around Senai airport.  I am rather pleased with the result, so I thought I make it available for all of you. Obviously, you are not supposed to use this “chart” for actual navigation,but at least if you hear FRAS69 (me) announcing my position you can use the map to determine roughly where I think I am.

The chart is available as vector graphic, PDF and JPEG in the download section of my web site.  The vector graphic version can be edited with Inkscape (and probably with other vector graphic software applications as well.
