An Excel spreadsheet to calculate the descend rate, time, angle and length when approaching an airport for landing.
When on an instrument landing (ILS/VOR/NDB) to an airport using the official airport approach plates:
Input values from the approach plate:
 Start height (highest point)
 End height (lowest point)
 The distance between these 2 points
And the average speed between these 2 points
The spreadsheet will calculate:
 descend time
 descend rate
 descend angle
 descend length
As an example, a part of the approach plate from the airport KALAELOA  JOHN RODGERS FIELD (PHJR), approach VOR/DME 04R
Input values for the green part:

Input values for the yellow part:
