# Format for CRZ PERF tables

Columns delimited with `;`

First column is altitude

Second column is FF per engine in kg/hr
-  Column contains values for weights ranging from 140t to 290t in 10t increments
-  Delimited with `,`

Third column is IAS
-  If single value, apply to all weights
-  If multiple values, apply to respective weights (delimited with `,`)
 
Fourth column is MACH
-  If single value, apply to all weights
-  If multiple values, apply to respective weights (delimited with `,`)

# Format for ECON tables
2d matrix of mach values

Columns delimited with `,` \
One file per altitude and MMO combination

First index is weight (equates to the lines in the file)
- Must be of 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240, 250, 260, 270, 280, or 290
  
Second index is CI (equates to the columns in a line)
- Must be in range $[0, 999]$
  
# Format for raw curve tables
2d matrix of curve parameters

Columns delimited with `;` \
Parameters delimited with `,`, ordered $a, b, c$

First index is altitude (equates to lines in the file)
- Must be of 250, 270, 290, 310, 330, 350, 370, 390, 410, or 430

Second index is weight (equates to the columns in a line)
- Must be of 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240, 250, 260, 270, 280, or 290

#### Usage of function
$$
  f(x) = a \cdot \sqrt x + b \cdot x + c
$$
Extract parameters $a,b,c$ from the table \
$x$ is the CI and must be in range $[0,999]$ \
$f(x)$ is the mach number for the given altitude, weight, CI, and MMO

# Conversion of weight to index

$$f(x) = \frac{x - 140}{10}$$
$x$ is weight (see range restrictions where applicable)\
$f(x)$ is the resulting index for the LUTs

# Conversion of altitude to index

$$f(x) = \frac{x - 250}{20}$$
$x$ is altitude (see range restrictions where applicable)\
$f(x)$ is the resulting index for the LUTs
