Mr Bernoulli, lack of recent experience would lead to a higher workload, however that link is no more than a casual factor here, the increased workload was due to a Single Pilot IFR flight at night in very poor weather conditions. If you have never operated in these conditions, well I have, and can assure you a 'high workload' is a realistic description.
If you read the report those points will become clear.
The report makes very sober reading, especially to one who knew the Pilot. I do not agree with the whole report but on balance perhaps it is not too far from what actually happened that fateful night. The linking of the Liverpool accident is probably relevant, however this accident
http://www.aaib.dft.gov.uk/sites/aai...pdf_501869.pdf is probably more relevant.
On an aside, Loganair have lost 3 hulls in the last 10 years, 5 aircrew killed in these accidents, makes you think....
