My instructor in the UAS told me to sit in the bath and imagine the runway threshold approaching. He said "use the rim of the bath to represent the dash of the instrument panel and try to get the perpective of the approach whilst saying your landing checks out loud" (made sure everyone was out of the house first-that would have seemed a bit obsessional; "your son is so obsessed with flying, he even pretends to fly the bath!!" Men in white coats, what, where??!!)
Always did think the Grob handled like a bath tub!!
Although RAF training is usually second to none, on that occasion I preffered the traditional methods of judging the flare...actually practising in a PA28!!
