Transport Wander
According to my JAR Instrumentation course notes the sign convention for an aircraft flying east would be negative and the opposite for west. That is, the gyro would drift by e.g. -7.94 degrees per hour for an aircraft flying East at 400 kts along 45N. Now, with a different set of notes the sign convention has changed and I'm struggling to visualise the mechanics of Transport Wander.
Any gyro boffins out there?
