Aircraft speed limits
Know which speed limit applies to your location.
Your learning goals
- Apply the broad limit.
- Recognize the limits and exceptions that affect this flight.
- Explain a decision using the scenario and supporting rule.
The broad limit
Below 10,000 MSL, the general maximum is 250 knots indicated airspeed unless the Administrator authorizes otherwise. It says below, not at or below. These are indicated speeds, not groundspeeds. Aircraft limitations may be lower.
The 200-knot places
- At or below 2,500 AGL within 4 NM of the primary Class C or D airport: 200 KIAS, unless ATC authorizes or requires otherwise. This paragraph does not apply inside Class B.
- Under a Class B shelf, or in a designated VFR corridor through Class B: 200 KIAS.
- Inside Class B itself: do not assume a universal 200-knot limit; the general below-10,000 limit still applies.
Exceptions are specific
If the minimum safe airspeed for a particular operation exceeds a §91.117 maximum, that minimum safe speed may be used. This is not permission to choose an unnecessarily fast cruise. Keep slower limits from aircraft documents and clearances in view.
FLIGHT SCENARIO
What would change your plan?
You are below a Class B shelf at 230 KIAS and 4,500 MSL. Is being below 250 enough?
- NoticeWhat does this situation require?
- VerifyWhat evidence is still missing?
- DecideWhat keeps an option open?
Compare your reasoning
No. The airspace beneath the shelf has a 200-KIAS limit. Being outside Class B does not eliminate that restriction.
SUMMARY
Know which speed limit applies to your location.
No. The airspace beneath the shelf has a 200-KIAS limit. Being outside Class B does not eliminate that restriction.
Before moving on, explain the decision in your own words: what would you verify, and what would make you change the plan?
