I was asked about latency today, so I decided I should actually measure it. The video below show the latency test. The top screen is the Airplay receiver (Apple TV), the lower left screen is the original source clock with the Mavic pointing at it, and the right screen is the display on the Mavic's controller.

Summary:

• Mavic to Controller latency: ~200ms
• Controller to Airplay latency: ~100ms
• Mavic to Airplay latency: ~300ms
