Pilotcredentials.com says. "Commercial Pilot Certificate with Multi-engine and Instrument rating without limitations, ATP Certificate".

So technically, one is eligible to apply with an ATP single engine land or helicopter as long as they have Commercial with multi-engine instrument! With those requirements, does FedEx offer the ATP-CTP course to new hires with those ratings to be eligible for the ATP multi-engine? My guess is they will never interview you unless you have an ATP with multi-engine land so why publish lesser requirements?
