data |
A data frame |
settings |
A list for re-defining constants. See details |
method |
Methods for fuel management |
speed_control |
One of two speed control methods. By default constant_speed is used. vvmp_constant is the alternative. The former holds the true airspeed constant while the latter holds the ratio of true airspeed and minimum power speed constant |
protein_met |
Percentage of energy attributed to protein and metabolism |
The option *control takes the folowing arguments
ppc: Profile power constant
eFat: Energy content of fuel from fat
eProtein: Energy content of protein
g: Accelaration due to gravity
mce: Mechanical conversion efficiency [0,1]
ipf: Induced power factor
vcp: Ventilation and circulation power
airDensity: Air density at cruising altitude
bdc: Body drag coefficient
alpha: Basal metabolism factors in passerines and non passerines
delta: Basal metabolism factors in passerines and non passerines alpha*bodyMass^delta
invPower
speedRatio: True air speed to minimum power speed ratio
muscDensity: Density of the flight muscles.
phr: Protein hydration ratio
