The actual time in the air would be 5.9 hours (probably longer, since spec sheet range numbers usually are at economy settings, but speed is quoted at 75%). Two fuel stops, however, are going to add 1.5 hours (45 minutes per stop, which is conservative) for a total of 7.3 hours.
A normal lens or normal prime is a lens with a focal length about equal to the diagonal size of the film or sensor format, or that reproduces perspective that generally looks natural to a human observer under normal viewing conditions.
All Nikon zoom AF-lenses have focal length encoders added. Nikon AF-P: The lens contains a pulse motor (utilizing stepping motors) to focus smoother and quieter than previous drive systems. Nikon AF-I, Sigma/Tamron/Tokina: no designation: The lens contains an integrated focus electric motor.
