VH-XXX;
You can't claim a tailwind!
May 1974. FL 240 ISA, night flight Dubbo to Sydney 3 POB V35TC VH-DLO, 200 Kts straight and level before descent, normal predicted TAS.
GPS wasn't invented then. I descended at book figures, but ATC wanted a high speed ability below 10,000 due traffic separation which was accomplished OK.
A good tin aeroplane is probably as good as your modern "plastic fantastics"
