Ace the SkyWest ERJ 175 Limitations Test 2026 – Soar to Success with Confidence!

The main idea here is the legal speed limit below 10,000 feet. In U.S. airspace, you’re limited to 250 knots indicated (Vmo) when you’re below 10,000 ft MSL, regardless of aircraft type. That regulatory limit is what you use for normal operations in that altitude band.

The other numbers refer to different concepts or configurations (for example, a gust-penetration speed like 270 knots or Mach 0.76 is used in certain turbulence or high-altitude scenarios, not the standard below-10,000-ft limit). They aren’t the basic operating limit at low altitude.

So 250 knots is the correct value.
