Royal Jordanian Dash8-400Q?

Amadeus shows that Royal Jordanian’s subsidiary, Royal Wings, currently have 3x weekly AMM-Alexandria/ALY (Egypt) flights with DH8s (DHC-8-300) but from 31/10/05 the service becomes 5x weekly but with DH4s….

Isn’t the DH4 the Dash DHC-8-400Q? But Royal Wings only have DHC-8-300s and AFAIK they haven’t ordered the DHC-8-400Q…or have they?
