  faa.tg.constants.NaturalConstants

public class NaturalConstants
extends java.lang.Object

 NaturalConstants is used to hold all of the static constants
 to be used in the TGF package. These constants are common to
 all parts of the simulation.

 

See section 13 of the Detailed Design Document for a discussion of design issues.

Constant Field Values

SEALEVEL_PRESSURE

public static final Pressure SEALEVEL_PRESSURE

Standard sea level pressure

SEALEVEL_TEMP

public static final Temperature SEALEVEL_TEMP

Standard sea level temperature

SEALEVEL_DENSITY

public static final Density SEALEVEL_DENSITY

The density at sea level during standard conditions.

GRAVITATIONAL_ACCELERATION

public static final Acceleration GRAVITATIONAL_ACCELERATION

GRAVITATIONAL_ACCELERATION is the acceleration due to gravity. In this case, units are in feet/seconds-squared

TEMP_LAPSE_RATE_RANKIN_PER_FT

public static final double TEMP_LAPSE_RATE_RANKIN_PER_FT

Constant Field Values

GAS_CONSTANT

public static final double GAS_CONSTANT

Gas constant as defined in units of (square feet)/(seconds squared * R).

Constant Field Values

SEALEVEL_SPEED_OF_SOUND

public static final Speed SEALEVEL_SPEED_OF_SOUND

The speed of sound at sea level during standard conditions.

CONSTANT_TEMP_BREAK_ALT

public static final Altitude CONSTANT_TEMP_BREAK_ALT

Altitude of the gradient layer/isothermal layer boundary (tropopause) in the ICAO standard atmosphere. Below this altitude the temperature decreases linearly with altitude; between this altitude and the top of the stratospheric isothermal layer, the temperature is constant. Defined as 11 kilometers. (As taken from BADA which referenced the ICAO standard.)

PRESSURE_AT_ISOTHERMAL_BREAK

public static final Pressure PRESSURE_AT_ISOTHERMAL_BREAK

Pressure at the boundary of the gradient layer/isothermal layer (tropopause) in the ICAO standard atmosphere.

TOP_OF_ISOTHERMAL_LAYER

public static final Altitude TOP_OF_ISOTHERMAL_LAYER

Top of the stratospheric isothermal layer in the ICAO standard atmosphere. Betweeen the tropopause and this altitude, the temperature is constant. Defined as 20 kilometers.
