I agree that this topic is critical to safety.
I have been the on-board engineer for a number of ferry flights between Cape Town and various destinations as far as Abidjan on the West Coast and Pemba on the East and my very basic Portuguese and French has been invaluable to the pilots who were busy eneough with the flying without trying to decode Portuguese/French or terribly spoken English.
Some of these pilots have been new to Africa, let alone ferry flying in Africa and they have been often at wits end trying to understand things.
