[SU11 Beta] SDK Runway airport data

There are two confusing references in the SDK for the runway: For heading |
The heading of the runway, from 0.0° to 360.0°.
—|—
Is this True Heading - assume yes. for heading | Angle compared to true
magnetic north which the plane will face when starting, measured in degrees
between -360.0° and 360.0°
—|—
Assume this is also True Heading and Magnetic is an error. Also -360 is an
error - assume zero

Hello! Thanks for pointing this issue out. The docs will be updated for the
public SU11 release to explain that these are both relative to true north.
