Sorry enough: Those Starting-Points are not defined for all airports - due to the limited availability of unpaid volunteers. But You can define your own “parking.xml” or add parking-lots to an existing one according to the above scheme – for HowTo get additional [[GPS]]-data see the next chapter! That way you could create your own personal “VIP-Parking” for your most favorite airports!

[[File:KRHV-startpoistion.png|250px|thumb|left|]]1. Open [[MPmap]] and zoom into the airport you wish. Move your Mouse-pointer to the place you want – e.g. to the place on KRHV where “jomo” is parked now. And then read the lat/lon-data in the upper right corner (see the big red arrow). In addition decide on the direction you want to view: In the example on the left that is parallel to runway 31R, i.e. 310°+14°=324°. (The 14° are the difference between the magnetic and the cartographic North-pole in that area – if you do not know it: Just try e.g. the 310° and vary the heading until you are satisfied – or try the next item!) | [[File:KRHV-startpoistion.png|250px|thumb|left|]]1.

This is a wonderful way to test unique parts of a flight: With that Option you can start at unique locations and start your exercise, e.g. a “final approach”, or flying towards a NDB under different wind-conditions, etc. | This is a wonderful way to test unique parts of a flight: With that Option you can start at unique locations and start your exercise, e.g. a “final approach”, or flying towards a NDB under different wind-conditions, etc. | ||
As reference-point you can choose any navigational aid available in FlightGear, e.g. VOR, NDB, FIX, Carrier, airports – whatever! But watch out: For some VOR's and NDB's there may exist multiple stations with the same ID! e.g. there is a VOR “RIED” with the ID=”RID” southwest of EDDF (Germany). | As reference-point you can choose any navigational aid available in FlightGear, e.g. VOR, NDB, FIX, Carrier, airports – whatever! But watch out: For some VOR's and NDB's there may exist multiple stations with the same ID! e.g. there is a VOR “RIED” with the ID=”RID” southwest of EDDF (Germany). Another VOR “RID” exists in Richmond (Indiana, USA) - thus you never know where you end up. That does not happen very often – but you should be aware of that “mishap”!

:that will place you directly over a FIX for the ILS approach for runway 27R at KOAK. The speed (vc=100) fits to a C172 and the altitude (1500) is the proper altitude on the glide-slope for that. So this is a good Start for training visual Approaches (and or ILS). Other FIX-points you may find by opening [[MPmap]] in the area you are interested in and search for “all fixes”.

This is the easiest way to start – and thus often used to get beginners into the air for the first time! But as I pointed out at the beginning you should use this option only when you are all by yourself, that means without [[Howto: Multiplayer|Multiplayer]] activated! And all of us will be very thankful if you promote not to use this option when other [[Howto: Multiplayer|Multiplayer]] are in the area! | This is the easiest way to start – and thus often used to get beginners into the air for the first time!

This is even worse than the above! To all that bad happenings from before you are now even prone to start in a different direction to the other traffic!
