* $W_{to}est估算$
$log_{10}W_{TO} = A+Blog_{10}W_{E}$

| Type | A | B |
|:------------------------------ |:------:|:------:|
| Homebuilts High-Wing Kitplanes | 0.5886 | 0.8958 |
| Twin Engine Propeller Driven | 0.0966 | 1.0298 |
| Regional Turboprops | 0.3774 | 0.9647 |
| Transport Jets | 0.0833 | 1.0383 |

* $W_{tfo}=M_{tfo}W_{TO}$
For most aircraft 0.5%

* $M_{Fres}$
Reserve Fuel Weight as Fraction of Weight Used in the Mission
$M_{Fres}=\frac{W_{Fres}}{W_{Fused}}$

* $M_{ff}$
Mission Fuel Fraction
$M_{ff}=1-\frac{W_{Fused}}{W_{TO}}$
