CFB Edmonton (Namao) is a military field just outside of Edmonton. All aircraft touching down at Namao require a PPR (Prior Permission Request) number, and have to recite it to the controller at first contact.
One day, a Tomahawk from a local flight school announced inbound for circuits. The controllers asked for the PPR #, and the pilot said they didn’t know about one. The controller cleared them right-base for 29.
Tomahawk: “F-XAA is final 29, touch and go.”
Tower: “XAA is cleared touch and go, 29”.
Tomahawk: “F-XAA is final 29, touch and go”
Tower: “F-XAA is cleared touch and go, 29. How many more circuits were you planning on making?”
Tomahawk: “We though we’d make one or two more.”
Tower: “Roger. I just wondered because we were calculating your landing fees, and you’re up to $13,000 now.”
Tomahawk: “THAT WAS OUR LAST ONE!!!!!”
Tower: “Just kidding. Next time, read your flight supplement.”
