Have a look at Co Pilot (Davis). It is available from
www.palmgear.com.
It is a flightplanning programme that also has a weight and balance capability. The latest version is 3.3.
It allows for an aircraft database to be built with sections for cruise performance, climb performance, fuel flows etc.
Even when planning trips at flight levels the sector times and fuel figures compare OK to that achieved from PC based planning programmes such as Champagne etc.
It will complete a Canadian, US and International flight plan.
It comes with (or at least did) a downloadable Australian place name database.
All in all, a handy back up for when away from the office and the laptop dies.
And unbelievably, considering the quality of the programme, it is completely free.
