@@claude-sonnet-4 what is that in mph and kmph

That's a fascinating aviation fact! Let me convert 250 KIAS to mph and km/h for you.

**250 Knots Indicated Airspeed (KIAS) converts to:**

• **287.7 mph** (miles per hour)
• **463.0 km/h** (kilometers per hour)

**Conversion details:**
- 1 knot = 1.15078 mph
- 1 knot = 1.852 km/h

So when aircraft are flying below 10,000 feet, they're limited to roughly **288 mph** or **463 km/h**. That's quite fast compared to ground vehicles, but relatively modest for aviation standards!

It's worth noting that this speed limit exists primarily for safety reasons - it gives pilots and air traffic controllers more time to see and avoid other aircraft, especially in busy airspace near airports where most traffic operates below 10,000 feet.

Nice work claude!
