Not only DHL in the Middle East that raises my eyebrows.
I was at a B727 approved maintenance outfit in the UK, lets say 10years ago plus. There was a US registered B727 on hire/transfer to DHL based in BRU I had a look inside. Although it appeared to have all the legal radio equipment for the period,(including coffee grinder ADF's) I never saw a GPS receiver on board. My first thought was "how shortsighted!" as any GPS installation on the a/c would have paid for itself in fuel savings, in a very short period of time indeed by more accurate direct routing's etc., apart from making the pilots feel a lot happier.
Left me thinking, if this is how the DHL management "think", what else are they skimming on?
