What is the danger zone of the A/S 47A-1?

• A. 5' semicircle from exhaust and 180° to either side
• B. 10' semicircle from GTE (Huffer) exhaust and 90° to either side
• C. 20' semicircle from exhaust and 360° around
• D. 15' semicircle from any engine exhaust

Answer: (B)

The danger zone of the A/S 47A-1 is specifically defined as a 10-foot semicircle from the Ground Turbine Engine (GTE) exhaust and extends 90 degrees to either side. This measurement is critical for ensuring the safety of personnel and equipment around the operating area of the huffer, which is used to start aircraft engines. The designated distance and arc reflect the potential hazards associated with the exhaust, including high temperatures and possible jet blast effects. Understanding these safety zones is essential to maintain operational safety and effectiveness while using this equipment. The correct answer emphasizes the need for personnel to remain at a safe distance from the exhaust to prevent injuries from heat or propulsion force. Other options either misstate the extent of the danger zone or the configuration—factors that are crucial for maintaining safety regulations in aviation operations.
