What is CAS in military?

Close air support (CAS) is air action by fixed-wing and rotary-wing aircraft against hostile targets that are in close proximity to friendly forces and requires detailed integration of each air mission with the fire and movement of those forces. Department of Defense Joint Publication 3-09.3.

What aircraft does the US use for CAS?

F4U-5 Corsairs provide CAS for U.S. Marines fighting the Korean War.

What is the best CAS aircraft?

The best aircraft for CAS in the Air Force is not a multirole fighter. CAS is better pro- vided by a specialized aircraft with a mix of other specialized and multipurpose aircraft to support operations. At present, the best aircraft for CAS is the A-10.

What replaced the Skyraider?

In the high-speed, jet-age world of the late 1950s, the Skyraider seemed to be a relic of an earlier time. It had performed well during the Korean War, but the Navy had decided to replace it with jet aircraft.

What does CAS mean in aviation?

Calibrated airspeed
Definition. Calibrated airspeed (CAS) is indicated airspeed corrected for instrument errors and position error (due to incorrect pressure at the static port caused by airflow disruption).

What does CAS stand for in government?

CAS is an acronym that stands for Cost Accounting Standards. CAS is one of two primary sets of “rules” about how government contractors are required to do their cost accounting. The other is the Federal Acquisition Regulation (FAR) Cost Principles, contained in Part 31 of the FAR.

What aircraft was used by VNAF for close air support of ground troops?

The VNAF continued to use the A-1 until the nation’s demise in April 1975. Warfare technology eventually surpassed the Skyraider, but in its prime—and for years beyond—it proved itself as a premier close air support aircraft.

How is CAS determined?

for navigation, CAS is traditionally calculated as one of the steps between indicated airspeed and true airspeed; EAS is used as a reference by aircraft designers, but EAS cannot be displayed correctly at varying altitudes by a simple (single capsule) airspeed indicator.

Was the propeller-driven A-1 the CAS star?

“Even many of those who favored the supersonic jets conceded that the propeller-driven A-1 was the CAS star” in Vietnam, wrote author Douglas Campbell in his book “The Warthog and the Close Air Support Debate.”

Do propeller-driven aircraft still have a place in the world?

Military jets as well, can shatter the sound barrier with ease, and hit top speeds that would be unfathomable to engineers who worked on the propeller fighters of WWII. But propeller-driven aircraft shouldn’t be dismissed so easily, as they still have their place in the world.

What is close air support (CAS)?

For US airmen, it was the first real combat experience against an enemy in proximity to friendly ground forces, a mission that would become known as “close air support,” or CAS. US airpower was controlled by the ground commander, who parceled it out in increments for the benefit of local ground units.

How does a propeller work?

The propeller produces a thrust and torque force by imparting momentum to the air around it. The reaction to this is a set of forces imparted by the motion of the air on the propeller. The torque of the engine turning the propeller also imparts forces to each blade.
