I was listening to this week's episode of The Finer Points, an excellent flying podcast, and I thought it was worth sharing what he said.
His first rule was regarding deciding what altitude to fly a trip at, and he reckons you should use a maximum of 1000 feet of altitude for every ten minutes of flight. So for my usual trip to Tauranga of 25 mins, we're looking at 2500ft. Whakatane at 50 mins would be 5000 ft. This all sounds logical and commonsense to me..
His second rule is more a rule of thumb, I guess. This is something that I've forgotten, that's if I ever knew this. He says True Airspeed increases over IAS by 2% every 1000 ft. We were doing 125kt indicated in the Arrow the other day at 5500ft and the GPS and DME both read 137, which is bang on, at least according to my feeble maths skills..

I hope it takes into account terrain, I wouldn't want to fly to Raglan at 1500. :P
Where's your sense of adventure? :-)
