Wiz wondered what the altitude ceiling on a dragon was.

Maximum speed, altitude ceiling, stuff like that's top secret."

Using his knowledge as a mechanic, he tuned his aircraft to give it an additional 4000 ft altitude ceiling.

Though the fighters were flying at a high altitude ceiling, they were still within the lethality envelope of the SAMs.

With the advancement in aviation and increased altitude ceiling the altimeter dial had to be altered for use both at higher and lower altitudes .

As a result, interceptors were designed with a large missile payload and a powerful radar, sacrificing agility in favor of high speed, altitude ceiling and rate of climb.

Because of the relatively low speed and altitude ceiling of propeller aircraft, this type is generally favored for the deployment of mobile billboards when fixed-wing aircraft are used.

While the MiG-15 did have a faster climb rate and operated in a higher altitude ceiling than the F-86, it suffered from problems with oscillation, poor pressurization, unexpected pitch-up at high speeds, unrecoverable spins, sudden stalls, and a particularly dangerous emergency fuel pump that could cause the aircraft to explode if improperly activated.

The PRC MiG-17s had higher altitude ceiling performance and in similar fashion to Korean War encounters between the F-86 and earlier MiG-15, the PRC formations cruised above the ROC Sabres, immune to their .50 cal weaponry and only choosing battle when conditions favored them.
