Hanno,
Hv Doniol passes the Chichester test by doing the Hp and azimuth precalculations the day before so that all that is done during the flight are octant observations that are directly compared to Hp for an intercept. The plot goes down on the chart immediately. No inflight sight reduction calculating. Other methods of reduction can be used the same way to pass the Chichester test. Doing inflight sight reduction and flying a plane without an autopilot at the same time seems impossible but this is what Chichester did with the Bygrave over 80 years ago.

Greg,
Thanks for those Hx - much more than I expected.
You did not make those calculations / drawings during flight, did you?
If you did, Does your exercise demonstrate the havDoniol is practical during flight?Did you do the calculations by hand?
What changes would you make now that you have this experience ?
Would you have preferred Bygrave or not?
In other words, do you think the havDoniol passes the Chichester test?
