Class Vario
java.lang.Objectjflight.vario.Vario
- Direct Known Subclasses:
- BrVario
- public abstract class Vario
- extends java.lang.Object
Basic class for Vario-access;
Implements only the basic, device-independent methods. The other
functions are declared abstract and have to be defined in the derived
class for a specific Vario. All these functions define the interface
that is/can be used by the main class.
Interface for the Vario-class(es).
The data supplied by any Vario are expected to be at least these:
A series of height-data and (optionally) windspeed-data.
The data are collected at regular intervalls. The intervall is also
supplied.
Start-and endtime are optional.
There may be marks (defining a certain time) which also may have a
coordinate. These coordinate values don't make sense in this
application (supplied by the GPS).
Notes:
- If no speeddata are available the first speedvalue is set to -1.
- Datavalues that were taken on the ground are marked with an
offset of -1000 in the speedvalue (except the first one).
This is done in the data used internally only, not in the stored values.
Tbd:
- How does mark-setting affect the regular intervalls?
- What about US-style settings: feet / feet per minute?
Multiple sets of flightdata in the vario may be joined to a single
flight. This is because there may be problems when switching to the
backup battery. The missing height-data shall be interpolated assuming
the time difference information is valid. The speed-data are set to the
glider-default.
If windspeed data are available the Vario-flight-data may be shortened
by the data before launch and after landing by setting a windspeed
threshhold. This can be done alternativly / in addition using constant
height (threshhold) too. Should be confirmed by the user. Note that such
an operation has to be done anyhow to map the vario-and GPS-data later.
The values removed are not really removed but marked by a windspeed of -1.
Device-independence: All Classes shall be designed in such a way that the main
program using them can rely on a basic set of methods that are
implemented by all implementations regardless of the real Vario-device
used.
