Fr/Nouvelles du projet FlightGear - décembre 2011: Difference between revisions

For this [[VFR]] trip we need a strong machine since we will go up from 4000 to about 10,000 feet and since we are in Africa, Tanzania , what better choice is there as the Cessna 208 Caravan, on wheels. We will take off from HTLM, [http://en.wikipedia.org/wiki/Lake_Manyara Lake Manyara], runway 12 (124.5 deg), that has an elevation of 4150 feet. Hit Shift-B so we don't drop off the runway.

We will have to change some settings before we take off. There is no snow where we are so: View=> Rendering Options=> Snow line=> Set to max. (5000M). We need a reasonable clear sky since there are quite a few bumps we could hit: Environment=> Global weather=> METAR source=> Fair weather.

Give full throttle and take off. Bank left and make a full circle so we gain some altitude and make a mental note of the airstrip, since this is the only one nearby. Look at the road West towards the airfield.  

You will notice that the airstrip is at the edge of a mountain ridge, the lake to the East is quite a lot lower.

We pass over the airstrip towards lake Manyara and turn left keeping the mountains close to our left side, on an initial course of about 30 deg. We keep the mountains to our left and follow our path, our heading will slowly go from 30 to North and takes about 15 mins. During our path we should slowly gain altitude.  

[[File:Ol Doinyo Lengai.jpg|thumb|250px|Mt.Kerimasi (left), Mt.Ol Doinyo Lengai (ahead)]]

On the '''image''' we see two distinct mountains. The nearest is Mt.Kerimasi, a fun place for hang-gliders, and North Mt.Ol Doinyo Lengai, an active volcano. We are heading straight towards [http://en.wikipedia.org/wiki/Ol_Doinyo_Lengai Mt.Ol Doinyo Lengai]. Just before we would collide we take a sharp left turn heading 225. You will see why we need the altitude now.

The mountain ahead, [http://www.ntz.info/gen/n00161.html#id03702 Mt.Embagai], we see does not appear to be anything spectacular. Aim towards it since we have to go over it.  

Coming nearer, if you are high enough, 9000 feet, you will see why this mountain is well worth a visit. It is a crater with a lake inside, lake Embagai (Empakaai). Enter the crater and look around, careful not to loose any height since we'll have to get out again, we need about 10 000 feet. Mesmerized we grab our compass and take a course of 225 again. To get out we might skim against a cloud, be careful. If you don't see a way out take a turn again to wait for the clouds to move out of sight.

After you managed to get out of the crater keep on the course of 225 while descending slowly for about 9 mins. There are some bumps to avoid, like Mt.Olmoti we keep to the right and Mt.Losirua on the left.  

After a small hill we enter one of the most amazing places in Africa, the [http://en.wikipedia.org/wiki/Ngorongoro_Conservation_Area Ngorngoro Crater], the second biggest crater in the world. A micro climate and amazing wildlife.

Examine the crater and you will notice two lakes, head towards the biggest lake, lake Magadi. When you are above it take a course of 123 to get out of the crater.

After leaving the crater it takes some time before we are near the airstrip again. After about 5 mins we will see a river (left) and a road (right). Follow the road since it will lead us to the airstrip again.

Don't scare the wildebeast!
