In 1960 a 15 minute TIF was 15 shillings ($1.50) and an hour dual was £4/10/- ($9) in a Chipmunk. At the time as a 16 or 17 year old I was earning £8/10/- per week.
In 1988/89 I owned a number of aircraft, don't remember all the training and charter rates but the Cessna 172 training rate was $110 solo and $125 dual.
