Under HIPSARM, for how many continuous minutes can AEO operations above MCP and up to MTOP be conducted?

• A. 30 continuous minutes
• B. 60 continuous minutes
• C. 15 continuous minutes
• D. 45 continuous minutes

Answer: (A)

The main idea here is that high-demand operations inside a defined altitude band are time-limited to protect performance margins. For AEO operations that occur above the MCP and up to MTOP, the standard allows only 30 minutes of continuous time. That 30-minute cap accounts for the increased power demand, engine and rotor heating, and the higher crew workload when operating in that envelope. Keeping it to 30 minutes ensures we stay within safe thermal and mechanical limits and maintain acceptable margins for recovering or exiting the operation. If more time is needed, you would exit the envelope—by descending below the MCP or moving to a different altitude band within MTOP—and then you can re-enter after conditions allow.
