For gawds sake don't turn up without PPR. The airport can handle multiple jet diversions at the drop of a hat but appears to go into meltdown* when a solitary C172 turns up without PPR
*This of course does not apply to EGGP ATC who handle the rubbish (planes & paperwork) thrown at them daily with aplomb..........
Plan on a standard VFR join as per the AIP. On first contact don't give your life story - "Liverpool Approach G****, VFR inbound with PPR" will do. When controller asks you to pass your details, do so and tag on that you are in receipt of the latest ATIS info and requesting a "Standard VFR join at *** for runway 27/09". The controller will be so overcome with your levels of local knowledge and preparedness he/she will probably offer you a more direct inbound routing; and whilst doing so thinking to him/herself - "Christ I wish all visiting pilots were this good...."
Catch my drift..............
Be seeing you soon.....................
