4Q about airport navigation

[dooom]

I now know how to utilize my ABRIS to get me home either to the assigned af or nearest af.

 

When i contact the tower and request a landing, i am often given a specific strip to roll in on. i notice from page 3-33 that the ABRIS can be progrmamed via MENU/OPTION/CHARTS to display airports, runways ILS and Holding patterns....

 

These are all checked in my ABRIS, yet when i zoom in on the assigned AF, i cannot tell if i am lining up on runway 15 or 33.

 

Q: Does the ABRIS have the functionality to display this data? Approach patterns/runway numbering visually?

Q: Is my only option to print out Nav charts from Here: http://users.skynet.be/F4Checklists/LomacDownload.htm and refer to paper?

Q: If i do have to use the paper charts... I notice details such as seperate tower radio frequencies etc... can these be programmed into game for contact? (see attachment)

Q: What does the MSA circle on the chart mean (with the 4500m/450m) and the DH: 110m MSL/RVR 800m?

 

Thanks for your help.

if you are approaching runway 15, you would be facing south east. Runway 33 is facing north west. Runways get their names by rounding off the runway heading.

 

yes, there is a mod to change the frequencies, but it is a moot point as ATC will answer to any channel.

MSA is Min Safe Alt, but I am not sure if that is what the chart refers to. Might be an airspace restriction for airport classification.

AHA!

 

great to know ... ergo the bearing of runway in the attachment is 151 deg and 33 is 331 deg.

 

+1 - thanks for the clarity!

 

Now how abou the other questions:music_whistling:

Runway 15 is 150 degrees, runway 33 is 330 degrees.

1. I believe in real life the ABRIS can have multiple charts stored in it, like approach plates and such but in game all you have is the one "general terrtain" chart. So the in-game ABRIS doesn't show very much detail. You might get some more text info about an airfield if you searched for it through the Nearest>Airfield list.

 

2. I think there are some airport diagrams / approach plates included in the game's manual or in some other directory. This is another place for looking: http://chartfinder.vatsim.net/

 

3. The game has all tower frequencies on 127.5 and all ATC functions (ground, tower, etc) are considered "tower." You can change the tower frequencies via LUA edits in the game files if you want to have "realistic ATC frequencies."

 

4. The MSA circle tells you local safe altitudes split up into pie wedges. The example you posted is "For 100km radius, you need to be at 4500m altitude to be safe anywhere from 270° to about 110° direction from the airport center. From 110° to 270° you have to be 450m altitude to be safe from terrain and obstructions."

 

DH is "Decision Height" for precision approaches for the altitude on approach you can get down to before you have to decide whether or not to go around based on if you've acquired visual reference with the runway. Non-precision approaches have a MDA-MAP (minimum descent altitude / missed approach point) pair of values that does a similar thing.

 

RVR is required runway visibility and is the minimum horizontal visibility at the runway's surface to safely operate.

 

Runways are labeled by the first two digits of their magnetic runway heading +/-15°. A runway direction of 017° would be "Runway 02." It might help to set the DT white arrow in manual mode and turn it to match the runway direction just as a reminder after the runway is known.

Q: What does the MSA circle on the chart mean (with the 4500m/450m) and the DH: 110m MSL/RVR 800m?

 

RVR = http://en.wikipedia.org/wiki/Runway_visual_range

 

DH = Decision height (DH) is a specified height above the ground in an instrument approach procedure at which the pilot must decide whether to initiate an immediate missed approach if the pilot does not see the required visual reference, or to continue the approach. Decision height is expressed in feet above ground level.

 

MSA = The minimum altitude depicted on approach charts which provides at least 1,000 feet of obstacle clearance for emergency use within a specified distance from the listed navigation facility.

awesome - thanks butcher
