pycontrails.FlightPhase¶

class pycontrails.FlightPhase(value, names=<not given>, *values, module=None, qualname=None, type=None, start=1, boundary=None)¶

Flight phase enumeration.

Use segment_phase() or Flight.segment_phase() to determine flight phase.

Methods

`conjugate`()	Returns self, the complex conjugate of any int.
`bit_length`()	Number of bits necessary to represent self in binary.
`bit_count`()	Number of ones in the binary representation of the absolute value of self.
`to_bytes`([length, byteorder, signed])	Return an array of bytes representing an integer.
`from_bytes`([byteorder, signed])	Return the integer represented by the given array of bytes.
`as_integer_ratio`()	Return a pair of integers, whose ratio is equal to the original int.
`is_integer`()	Returns True.
`__init__`(args, *kwds)

Attributes

`real`	the real part of a complex number
`imag`	the imaginary part of a complex number
`numerator`	the numerator of a rational number in lowest terms
`denominator`	the denominator of a rational number in lowest terms
`CLIMB`	Waypoints at which the flight is in a climb phase
`CRUISE`	Waypoints at which the flight is in a cruise phase
`DESCENT`	Waypoints at which the flight is in a descent phase
`LEVEL_FLIGHT`	Waypoints at which the flight is not in a climb, cruise, or descent phase.
`NAN`	Waypoints at which the ROCD is not defined.

LEVEL_FLIGHT = 4¶: Waypoints at which the flight is not in a climb, cruise, or descent phase. In practice, this category is used for waypoints at which the ROCD resembles that of a cruise phase, but the altitude is below the minimum cruise altitude.

as_integer_ratio()¶

Return a pair of integers, whose ratio is equal to the original int.

The ratio is in lowest terms and has a positive denominator.

>>> (10).as_integer_ratio()
(10, 1)
>>> (-10).as_integer_ratio()
(-10, 1)
>>> (0).as_integer_ratio()
(0, 1)

bit_count()¶

Number of ones in the binary representation of the absolute value of self.

Also known as the population count.

>>> bin(13)
'0b1101'
>>> (13).bit_count()
3

bit_length()¶

Number of bits necessary to represent self in binary.

>>> bin(37)
'0b100101'
>>> (37).bit_length()
6

from_bytes(byteorder='big', *, signed=False)¶

Return the integer represented by the given array of bytes.

bytes: Holds the array of bytes to convert. The argument must either support the buffer protocol or be an iterable object producing bytes. Bytes and bytearray are examples of built-in objects that support the buffer protocol.
byteorder: The byte order used to represent the integer. If byteorder is ‘big’, the most significant byte is at the beginning of the byte array. If byteorder is ‘little’, the most significant byte is at the end of the byte array. To request the native byte order of the host system, use sys.byteorder as the byte order value. Default is to use ‘big’.
signed: Indicates whether two’s complement is used to represent the integer.

is_integer()¶: Returns True. Exists for duck type compatibility with float.is_integer.

to_bytes(length=1, byteorder='big', *, signed=False)¶

Return an array of bytes representing an integer.

length: Length of bytes object to use. An OverflowError is raised if the integer is not representable with the given number of bytes. Default is length 1.
byteorder: The byte order used to represent the integer. If byteorder is ‘big’, the most significant byte is at the beginning of the byte array. If byteorder is ‘little’, the most significant byte is at the end of the byte array. To request the native byte order of the host system, use sys.byteorder as the byte order value. Default is to use ‘big’.
signed: Determines whether two’s complement is used to represent the integer. If signed is False and a negative integer is given, an OverflowError is raised.
