Short dips below minimum oil pressure are allowed during negative-G as a brief exception to normal lubrication, but only for a limited time. The engine oil system can tolerate a temporary loss of pressure during these maneuvers, however extended drops increase the risk of bearing starvation and engine damage. The specified safety window is ten seconds, which provides enough time to complete the necessary negative-G maneuver while still protecting the engine.

The other time options would either be unnecessarily restrictive or exceed the safe duration; eight seconds is shorter than required for typical negative-G transitions, while twelve or fifteen seconds would allow oil-starvation conditions long enough to risk damage. Stay within the ten-second limit and recover to positive-G before exceeding it.
