About

In flight simulation, one of the things pilots have to do is calculate the deviation from the international standard temperature at a particular altitude. In order to figure out the proper calculation, we used this site, cited here, to get the two formulas:

• Formula of the ISA temperature at certain altitude:
  • 15 – [(height/1000) x 2] °C
  • Alternatively, calculator.academy uses a very similar formula that is not rounded up. The site also includes additional information regarding the usage of the formula.
• Formula of the ISA temperature deviation at certain altitude:
  • Actual temperature – ISA temperature

The example from calculator.academy (as cited above) demonstrates this very well:

1. AT = -30, Alt = 26000
2. ST = 15 - (1.98 * (26000/1000))
   • = 15 - (1.98 * 26)
   • = 15 - 51.48
   • = -36.48 degrees Celsius
3. ISAT = ST - AT
   • = -36.48 - (-30)
   • = -6.48

Both of these formulas are used in calculating vital components in air-temperature while at an altitude. We are given two variables:

• AT for 'actual temperature'. Calculated by using the aircraft's thermometer. This is in degrees Celsius.
• Alt for 'altitude'. This is calculated by using the aircraft's elevation readings.

With these variables we can calculate:

• ST for 'standard temperature'. Calculated by dividing the current altitude by 1000, then multiplying that by (2 or 1.98), ultimately subtracting 15 from that.
• ISAT for 'ISA temperature difference'. Calculated by subtracting the AT from the ST.

Directions

1. Pick your favorite programming language and build tool.
   • Java
   • Gradle (doc linked)
2. At least ONE unit test.
3. Set up a public GitHub repository for this activity.
4. Add unit tests and coverage report generation to the build configuration. The latter might require a language-specific plugin for your build tool, e.g., JaCoCo for Gradle or sbt-scoverage for sbt.
   • Add JaCoCo
5. Set up a GitHub action for automatically running the tests and generating the coverage report upon commits to the repo.
6. Add at least two status badges for in-process metrics and two more for complexity metrics; most of these would be based on hosted services.
   • How to add status badges.
7. Make several commits that trigger automated builds. Ideally, start with the unit test(s) failing and then fix them so we can see the build status changing from fail to pass.
   • (List of commits)
8. This example is much more complex than required but illustrates the other requirements of this activity.
9. Extra credit for additional actions and metrics/badges.
