Study Notes
Airspace Speed Limits Overview
- Mach 1 is a speed limit in the United States.
- Unrestricted speed is allowed at or above 10,000 feet Mean Sea Level (MSL).
- Below 10,000 MSL, the speed limit is 250 knots indicated airspeed (KIAS).
Class B Airspace Regulations
- Unrestricted speed at or above 10,000 MSL.
- 250 KIAS limit applies below 10,000 MSL.
Speed Limits in Specific Areas
- Beneath Class B or in VFR corridors through Class B, the speed limit is 200 KIAS.
- Procedure turns have a speed limit of 200 KIAS.
- In Class C or D airspace, at or below 2,500 feet Above Ground Level (AGL) within 4 nautical miles of the airport, speed is limited to 200 KIAS unless otherwise directed by Air Traffic Control (ATC).
- Recommended 200 KIAS in Class E or G airport traffic patterns.
Exceeding Airspeed Limits
- Per regulation 91.117(d), exceed airspeed limits if the minimum safe airspeed for the operation requires it, without needing to notify ATC.
ATC Speed Limits
- When ATC issues a speed limit while vectoring, continue to comply even with changes in altitude.
Key Speed Limit Exceptions
- Below 10,000 MSL and/or in Class B, the speed limit remains 250 KIAS, even when instructed to maintain best forward speed.
- At 10,000 MSL and above within Class B airspace, speeds are unrestricted.
Descending and Transitions
- While descending from above 10,000 MSL to below, the aircraft must be at or below 250 KIAS before entering Class B airspace.
Coastal Airspace Considerations
- The 250 KIAS limit below 10,000 does not apply beyond 12 nautical miles from the coastline.
Provisions within 4 Nautical Miles
- Within 4 NM of Class C, D, E, or G at or below 2,500 AGL, the speed limit is also 200 KIAS.
Holding Pattern Speed Limits
- At 6,000 feet MSL and below, speed is limited to 200 KIAS.
- Holding at altitudes from 6,001 to 14,000 feet has a speed limit of 230 KIAS.
- Above 14,001 feet, the holding speed limit is 265 KIAS, maintaining a 1.5-minute outbound leg.
Approaching Clearance Limits
- When three minutes from a clearance limit, reduce speed to not exceed maximum holding airspeed or sooner to avoid holding altogether.
Approach Speeds by Category
- Category A: 0-90 Knots (1.3 times Vso)
- Category B: 91-120 Knots (1.3 times Vso)
- Category C: 121-140 Knots (1.3 times Vso)
- Category D: 141-165 Knots (1.3 times Vso)
- Category E: Above 165 Knots (1.3 times Vso)
