What is the V wiper ops MAX value?

• A. 230
• B. 160
• C. 250 (SW)
• D. 195

Answer: (C)

Windshield wipers are limited by a maximum operating speed to prevent damage from the air streaming over the windscreen. The V wiper ops MAX value is that upper speed at which you’re still allowed to use the wipers (in IAS). For the Embraer 175, this limit is operator-specific. In Southwest-configured aircraft, the wipers are certified to operate up to 250 knots, so the correct value is 250 (SW). Other operators or installations may have different limits (for example, 230 knots), which is why the Southwest designation matters here. The 250 knots reflects the specific certification for the Southwest E175 wiper system.
