Depends what is really meant by "Financial Advosor". In the UK, a financial advisor is someone, either working independently or tied to a finance house, who sells financial products i.e. they are salesmen, working for commission and very few qualifications are needed.
Many are not looked upon favourably as people have been missold pensions and mortgages.
However, there are also finance and accountancy qualifications which require a degree plus three or fours study (through Articled Internship) to gain. The academic standard for that is much higher than ATPL.
However, pilots and aviation are more glamourous than finance.
