Flight Critic (Flight Statistics - Takeoff/Landing Distances etc., Grading/Scoring)

[pilotjohn]

EDIT: Update version attached. See changes in the post below.

Attached is a script that will automatically record and analyze your flight, providing statistics like takeoff and landing distances, and provide a comfort and skill grade/score for different phases of flight (think of comfort as how the passengers feel, and skill how the check airmen - or DPE - will rate you). It correctly identifies takeoffs and landing points on rough terrain or bounces (event multiple bounces). The raw data is saved and can be fed through the script via the command line for re-analysis. The final output is also saved as a text file. Here's a sample analysis:

Updates...

Better landing/takeoff detection on large/long bounces

Pseudo Gaussian distribution of scores (50% = average)

Perception weighted scoring (worst part of a score gets the most weight)

Category deductions shown for each score
