Errrrr......well, just after qualifying a good few years ago, I went on a late afternoon flight.....first ever pax next to me....(BTW very good looking blonde who I was out to impress!) Sun low in sky, and called small grass strip A/G radio....informed them I was rejoining....copied circuit details, QFE etc....came into overhead, did the descent deadside, and crossed the field.....thought....UMMMMM houses look bigger than normal......WHOOOPS....forgot to set Airfield QFE on subscale....insead of coming across the field at 800' aal, I wwas actually at 300'aal......needless to say, it was a sphincter tightening moment,as I calmly opened the taps, and climbed back to the correct height on the correct QFE.....
Blush.....
Happy to say that I have not repeated the faux pas
