Casio Pro fx-1 card reader programmable

[Geoff Quickfall]

These are not elegant examples of coding!!!! I wanted to see how the calcs performed so I quickly wrote these routines in a language I was not familiar with. Yes have programmed in FORTRAN but not like this!

Hope they give you ideas.

The moon phase is not my program and I am trying to remember and/or find the link. I will update the citation when i find it.

Cheers, Geoff

P.S. they are beautiful machines to say the least.





Great circle distance and track





Intermediate latitude



Cold weather (temp<10’C application):



Fuel in tank at prior to departure: fuel in tank is a check that the fuel IS in your tank ;-)

A = TOTAL FUEL AFTER REFUELLING IN KILOGRAMS -

B = ARRIVAL FUEL IN KILOGRAMS

C = FUEL REQUIRED TO BE LOADED.

D = TENDER UPLIFT (FUEL LOADED IN LITRES)

E = FWCF (SPECIFIC GRAVITY OF ‘A’ OR ‘A1’ KEROSENE (SG)

F = TENDER UPLIFT IN KILOGRAMS

G = DIFFERENCE IN KILOGRAMS

DIFFERENCE BETWEEN THE THE ‘C’ AND ‘F’ ON THE 787 AND 777 MUST BE < 5%.

C = A - B

F = D X E

G = C - F

% = (A - G) / A * 100. (Left this bit off the code as I am more interested in the difference in kilograms, especially if under required or making the aircraft over max taxi, ramp or takeoff weight.




Moon Phase:



ETOPS legalities



Conversion routines; imperial to metric and back





Unfortunately these models will convert sexidecimal to decimal but not back so here is a routine that does what the HR->HMS functions do on the HP:

The routine is too long to include in the Intermediate latitude program which can convert your HMS latitude and longitude to decimal lat and Lon. But cannot convert it back to HMS.
