But you shouldn't have loaded in the QNH? You need to use pressure altitude not pressure height for a density altitude calculation?
I have no idea what you mean by pressure height. There are a few ways to figure out pressure alt. If you are in the airplane you just set 1013 in the kohlsman and read PA on the altimeter. If you aren't in the airplane you can figure it out if you know the true altitude MSL, and the QNH. If the QNH is lower than 1013 your pressure alt will be higher than your true altitude and vice versa. So it is true that you need a pressure altitude of 5,500 at 49C in order to get 9,300 density altitude, but if you are sitting in an airplane at a 3,100 ft MSL runway and your altimeter reads 5,500 ft. with a setting of 1013 the current QNH would have to be about 0960.

A trifle tricky sometimes then if you're using QFE?

Simplicity itself from Australia the land that gave you CS Hames and what are probably still the finest one volume technical manuals to the PPL and the CPL.

This is from Balloon at Brisbane.

No more on altimeters though. It's far too much of a wind up and probably totally irrelevant, or at the least ignored, in swamp flying.

Not too tricky.
According to that site it's the same sh*t different words.
pressure altitude = pressure height
density altitude = density height
all referenced to the international standard atmosphere 1013 hP or 29.92 hg
you say qfe we say field elevation
the math is the same

That is a very impressive story, especially when you consider that in order to have 11,500 ft density altitude at a 5,500 ft elevation runway the outside temperature needs to be in the neighborhood of 60 deg C. Must have been uncomfortable! I'm not sure how many places get 10K ft density altitude every day but I reckon not many of them are at 5,500 ft as it would require the temps to be consistently in the mid 40s C. So I can't imagine where where this heroic pilot is doing his flying, but I'm glad I'm not him.
OOPS. 9,500 not 11,500. My bad.
And WHK has had a few 40's recently.

You might get killed that way. QFE is the subscale setting that will ensure that your altimeter reads 0 at the appointed reference point. It is by no means the same as QNH. QFE does not work so well at high elevation airports or even medium elevation airfields such as HTKJ. It was beloved of the British air force and certain British airlines. It contributed a small extra cockpit workload especially in a go around situation, beloved of examiners when the candidate forgot to set QNH from QFE on the missed approach. That was an auto fail as far as the UK CAA were concerned.

Is it wrong that not only am I considering this for the future, but also massively excited at the prospect of it? It sounds like awesome fun haha.

Out of interest, is there internet at the camp? Ridiculous question but oh well..

Back on point, thankyou for the excellent post, it has really helped establish what is what about Africa..

There is WIFI at Old Bridge Backpackers not sure about Audi but I would guess so. There is also WIFI at the airport. The whole system is extremely slow and often down.

Hi all, I'm just wondering if there are many female pilots in Namibia or Botswana? Im from Australia and looking for a low time job for the next season and still need to do some research, but would like to know if there are many female pilots around?

In Maun there is 5, with one more to be hired soon.
2 have just recently left, one quit after getting fed up with being posted in Zambia, the other had to be let go after a problem with work permits.

Basically every girl that has turned up since I have been here has been hired with the exception of 1.

Ladies in the cockpit

I see more and more here in Nam as well. Actually it seems that if a girl shows up then she's got almost 100% chance to get hired.

I'm going to be busing it from Joburg to Gabs soon en-route to Maun. Only problem is the bus arrives in Gaborone in the evening then I have to wait until the next day to carry on the journey. Does anyone know of a cheap place to stay in Gaborone for the night
Thanks
