LASORS say that 5% may be added to the total for licence issue, therefore only 1425 hrs are required. It also used to state that taying hours should be declared as such and should not be added to aircraft totals to look like they are flying time. This is particualry relevant if applying to a non JAR airline as some operators don't recognise military taxy time.
One way round it is to keep a separate civilian logbook recording blocks times and not airborne times. This will make a significant difference in most cases as the times mentioned by Mr Bernoulli are based on a minimum time assumed spent taxying. The longest ground time I have ever spent was a few minutes short of two hours!
Mr Bernoulli, we obviously had similar careers. I added 448 taxying hours to my CV!
