would this include a diagram like the Howgozit
- not on the ones I have used, but they do have fuel expected columns from which you can derive surplus/(on a bad day) deficit by simple maths. I have never had cause to use a howgozit for many years with the advent of computer generated PLOGS. Actually, wrong - I did run a hyd quantity howgozit on the back of the docs envelope once when we had a hyd loss rate on an ETOPS flight.
