GFA have an incident recently in SA where a G109 returned from flight with no fuel and mentioned pilot miss read dip stick.
About 10 years ago I had to do a PAX flight and I did something similar when first glider I went to had master left on so went to falke and dipped it with a stick and miss read dip stick and took off with 8 litres where I thought it was 18 litres. I was in a hurry and mad at some body was such a fool to leave master on. Immediately after that I cut a flat spot on dowel dip stick up to 10 litre mark and marked that area "*too low to fly*". Never made the error again. Personally I will not or hate flying an aircraft with no dip stick. For dimona from Day 1 I took the tank to aeroweld and added a flange and bug to top of tank. Another I added the flange using the fuel tank sealant called ProSeal 120.and works well but must be real careful with making hole in tank. I would recommend this as dimona is very accurate down low level fuel and then I can accurately add fuel for a flight. Grob 109 and falkes are no worries with dip stick as with. Ximango can be dipped with stick. Just consider a too low mark by way of flat spot on your dip stick. Just a thought-I love dipsticks as they do not lie. Ian McPhee .
