I spent a fair amount of time flogging up and down between the UK and East Africa in the 1970s. Sorry to challenge the consensus, but I'm fairly sure EAAC's long-haul flights (Super VC10s by then) used "East African" as the callsign. Knowing pilots, "East Aff" would be a tolerable abbreviation for short-haul flights (DC-9s, F27s) on VHF, but it would not come over with sufficient clarity on HF R/T.
One person
Jhieminga might be able to contact for a definitive answer would be Gerry Surley (sorry, not sure of the spelling!), who performed engine runs on his former mount at Dunsfold last August.
BTW, if memory serves EAAC's station ops R/T callsign was "Eastair": e.g., "Eastair Nairobi."
