flight level

That way, if either plane encounters a problem that requires it to change its flight level, it can immediately disengage from the pairing and descend to a safe altitude.

As it approaches the lab, it is programmed to descend to a low flight level and eject a package containing the test samples so that they float down below a parachute onto an open space, in this case, the lab’s front lawn.

The 366th Fighter Wing said in an email that current flight level restrictions inhibit aircrew ability to become proficient in low-altitude tactics.

“Atlanta Center,” Bull said, “Marine 657 over Brunswick at flight level three-two-zero. Requesting a Tacon approach to Ravenel. Over.”

“Ravenel Approach, Marine 657 inbound. Sand Dollar intersection for Tacon approach. Flight level three-two-zero.”
