I would like to beg those visitors of the site that do single pilot IFR flights, to take the time and read carefully the suggestions of this excellent document. my 2c.
Really? Some mickey-duck CAA authority like NZ is any kind of authority on SPIFR over the industry experience of the FAA? Lots of single-pilot complex aircraft IFR flown here every day, normal. Not sure why you add "in IMC", are you even familiar with IFR? Find another windmill.
