Piperarcher, Fenland is a very harsh target for a nav diversion!
It certainly is. I have been back a few times recently, and even though I am now armed with a GNS430, a NATS Aware Device and an iPad, I actually dont have any problems finding it visually without this equipment. I think thats partly because I am now 7 years more experienced, but also the aforementioned equipment and using VOR's etc means I am more relaxed during flight and have adapted my planning and flying to a way that suits me and reduces in flight workload.
Draw the wind arrow on your map.
And note on the map the max drift at 2000ft and/or 5000ft so you can make fairly decent corrections in your head as go along. I find this easier than picturing a clock face on the DI and doing other maths in my head.
