- Calc MD before departure and write it on the PLOG, together with Wind details.
- Decide where to divert from/to.
- Sketch and estimate track. Check for gotchas
- At start point turn on to TRACK and note time
- Use DI to assess proportion of max drift on that heading and adjust heading accordingly, add variation and write down resultant heading (so far no calcs)
- Find wind direction on outside of DI and project horizontally to estimate proportion of windspeed that as head/tail component, write down groundspeed (still no calcs)
- Mark the rack with 6 minute markers (1/10 of groundspeed) and estimate ETA.
- Now run normal nav process.
Simples! and no calculations whatsoever.
