The Hughes YAH-64 underwent testing in the McKinley Climatic Laboratory from 2 November to 16 December 1981, consisting of 14.4 hours of operating time.

Operating time for patients on the heart-lung machine is twice as long as the off-pump procedure, so more anesthesia is needed with the bypass machine.
43.
The review also showed that the Nezhat articles reported substantially less blood loss and shorter operating times than what was reflected in the actual records.

However the VRDK was limited to only ten minutes'operating time per sortie, which meant that it was useless weight during the rest of the flight.

These devices offer the promise of a power source for portable electronic devices which is lighter weight and has a longer operating time than batteries.
46.
With a fuel capacity of 20 gallons of gasoline, it claims 15 to 18 hours of operating time and a top speed of 20 mph.
47.
During dynamic positioning operations the fuel consumption is 15 tons per day and the operating time depends on the distance and speed of transit to location.
48.
For more complex operations it would make sense to repeat the procedure a number of times, as StuRat said, and find a natural average operating time.
49.
Many of the government operated batteries had very short operating times, some for a year or two, while a few were 50 years or more in operation.

Error rates are typically proportional to the ratio of operating time to decoherence time, hence any operation must be completed much more quickly than the decoherence time.
