Assessment task: 

You are a member of the operations team working for CargoLogicAir. The business development team has identified Africa as the next location for a scheduled aircraft base. The aim is to connect the African continent with Europe and the Middle East. Your task is to identify three suitable freighter aircraft to locate at three different airports in Africa. Your team needs to deliver a proposal presentation which incorporates:

• a review of the potential commercial export and import market in African countries so as to select your three airports.
• an analysis of the aircraft types that would be suitable, based on cargo capacity and range.
• an analysis of airport infrastructure at your selected locations to match the ground handling requirements of your aircraft and any associated recommendations.
• an economic analysis of your proposal
my part is economic analysis only. 
we have chosen 3 routes from Africa.
Johannesburg to Frankfurt 
plane using 777-FBT-D-ALFA
Addis Ababa Bole (ADD) to Dubai World Central (DWC
Boeing 737-46J(SF) D-ACLG 
Cairo (CAI) to London Heathrow (LHR)
A330-243(P2F) SU-GCE 
you need to find out following stuff for economic analysis:
-how much fuel cost for each route individually, 
777-FBT-D-ALFA and A330-243(P2F) SU-GCE leasing price from any broker with valid website and 737-46J(SF) D-ACLG price because we are showing this is our own aircraft in the presentation. 
-the airport fee charges of Frankfurt, Dubai and Heathrow London.
-demand of each route 
-economic condition of Johannesburg, Addis Ababa and Cairo. why we chosen those destinations, flying from? does they have good GDP condition?
-please remember we are traveling Johannesburg to Frankfurt once in a day, Cairo to London twice in a day and Addis Ababa to Dubai twice a day because those are short flights
-also mention duration and km of each route so I can explain fuel cost.
