I have flown in Africa several years ago. Since you are talking about safaris, it will be one of the better areas. It will be an experience you can not buy anywhere.
It has two things going for it:
1. ME PIC. That is had to beat.
2. International experience. Another hot item for many employers.
After all it is only for 6 months. You will have an adventure that you will always remember. Airnet and the like will always be there. And the potential for a better job after Africa is higher because of your new ME PIC time.
A few points from experience if you decide to go.
First, you will need an International Certificate of Vaccination in addition to your passport. I suggest that you take a couple of passport photos with you. For IDs or replacement passport. Somewhere in my bags, I'd also have a photocopy of my passport, drivers licence and the like ID. For Vaccinations, you are only required to have Yellow Fever. However, I would also get Tetanus, Typhod, Meningitidis, Hepatitis (B) and Cholera.
For Cholera, take the pills not the shots. The pills make you sick enough as it is.
There are two different schools of thought on Malaria. I didn't take the shots, but used lots of bug spray and had at least one gin and tonic a day. Didn't like the taste, but then I didn't get malaria either.
With the current rate of HIV is Africa, forget about taking care of the little head while you are there. Makes no difference male, female, black, white, brown, yellow, whatever. The last information I had was that at the current rate, there will be no more Africa in 30 years or so. And HIV is one of the milder diseases there. One of the wilder ones is Ebola.
Most airports in Africa are Military or joint use airports. So get permission before you take photos. African jails are so bad that they defy imagination.
Get the background of the country you are based in or flying into. If it has a fairly current history of warfare, like the last 50 years or so, there is a good possibility of land mines. Also learn at least a few words of the local lauguge. Hello, Good Bye, Good Morning/Afternoon/Evening go a long way. That and a smile and a thumbs up. Usually no problems.
Listen to the guys who have been there before. They tend to know the local issues and customs and will keep you out of trouble.
Have fun.
