The ECM wedges S/I can have a maximum of how many wedges in total, and not more than how many per elevation band?

• A. 10 wedges total; 3 per elevation band
• B. 12 wedges total; 4 per elevation band
• C. 8 wedges total; 2 per elevation band
• D. 15 wedges total; 5 per elevation band

Answer: (B)

The idea being tested is how ECM wedges are distributed across elevation bands and the overall and per-band limits that govern that distribution. There are three elevation bands available for the wedges, and the system is designed so you can place up to four wedges in each band without overloading any single angle. That gives a total maximum of twelve wedges across all bands, ensuring balanced coverage in elevation while respecting power, cooling, and interference constraints. If you tried to put more than four wedges in one band, you’d exceed the per-band limit; if you tried to exceed a total of twelve, you’d run past the system’s overall capacity. So the allowable configuration is twelve wedges in total, with no more than four in any single elevation band.
