For God's sake make sure that Sleap;s arrival procedure is notified in the AIP, Pooleys, AFE Flight Guide and elsewhere!
This particular procedure cost a student a great deal of money and dented confidence, which all of us instructors wish to avoid.
If Sleap wish to be difficult about this, then they will get fewer and fewer student visitors. I personally, will not send students there, particularly for their QXC because of their high-handed attitude.
By the way, if you call on 122,45 at a weekend, you may be misled into thinking that they have full ATC.... it's actually A/G!!!!!!!!! You actually get CLEARANCES?????!!!!!!
