The phrase "assigned altitude" is correct and usable in written English.
It can be used in contexts related to aviation, military operations, or any situation where a specific altitude is designated for an aircraft or object.
Example: "The pilot was instructed to maintain the assigned altitude during the flight to ensure safety."
Alternatives: "designated altitude" or "allocated altitude".
Investigators said previously that the crew had first raised their problem with air traffic controllers about 11 minutes before the crash, after dropping rapidly from their assigned altitude.
Controllers can cope with the problems that were the first ones noticed on the hijacked planes in September: no radio response, no transponder signal or a deviation from assigned altitude or direction.
Curiously, it climbed above its assigned altitude.
Because the ideal viewing directions for these instruments are not the same, we assigned altitude ranges for which the spacecraft pointing is optimized for the science from each instrument.
After 22 minutes of flight, the aircraft passed its assigned altitude.
Once the rotation is stopped, neutralize the rudder, level the wings, and climb back to your assigned altitude.
An aircraft leaves the holding stack (a series of elliptical patterns flown at assigned altitudes while awaiting clearance to land), if there is one, and approaches a runway through an outer and an inner marker.
In a video about the new system, it indicated that jets and airplanes might diverge from the Metroplex routes — and their assigned altitudes — due to weather and air traffic.
Warner Communications keeps a jet plane at the disposal of its major executives, it flies at forty-three thousand feet, which is higher than any altitude assigned to commercial jets.
That was an indication of a very serious problem, since the plane was assigned to an altitude of 31,000 feet and was supposed to stay there to avoid other traffic.
And pilots will not have to push and pull at the throttles — in effect, repeatedly stepping on the gas, then coasting — to maintain the altitude assigned by air traffic controllers as they begin a stairlike descent.
