FlightGear will show snow all around you but that is not very realistic so let's clean up. View=> Rendering Options=> Snow line=> Set to max. (5,000M). | ||
We will fly towards and land at SPRF. If you would enter SLCC and SPRF in [[Kelpie]] planner you probably would not be able to find SPRF. To find SPRF I am adding an additional VOR-DME station and for a good fix give you another VOR-DME. Try Kelpie planner to plan this route and compare with this suggestion. | We will fly towards and land at SPRF.

Set [[NAV1]] to [http://en.wikipedia.org/wiki/Juliaca Juliaca] VOR-DME on 155.55 with a radial of 311° (magnetic). Set [[NAV2]] to Arequipa VOR-DME on 113.7 with a radial of 212°. During our flight we will fly with [[true altitude]] as set with [[QNH]], keep QNH updated. Arm the autopilot with the [[heading bug]] at 311° and an initial altitude of 13,500 feet. | ||

After passing Juliaca set the radial of NAV1 to 352° and set the altitude to 17,422 feet. We will fly from NAV1 and slowly increase altitude. | ||
At a distance of about 60 NM set the heading bug on the current course. Monitor the distance to NAV1, the radial of NAV2 and the distance to NAV2. At a distance of 74.5 NM to NAV1, a distance of 140.7 NM and at the '''radial''' intercept of NAV2 should be the runway. So, from 60 NM onwards, look outside the window, then at NAV1 and then NAV2 etc. | At a distance of about 60 NM set the heading bug on the current course.

Land on RW 30 (and not on RW 12 unless you are a show-off). Oh, there is a small hill in front of RW 30, just so you know. | ||
Decreasing speed at this altitude can be a bit tricky. The air is thin and does not give much resistance. Next to that, the difference between [[indicated airspeed]] and [[ground speed]] is very noticeable. The ground speed is much higher as the indicated airspeed. | Decreasing speed at this altitude can be a bit tricky. The air is thin and does not give much resistance.
