The FAA imposes a 250-knot speed limit below 10,000 ft for two reasons: traffic avoidance and bird strike risk. It can be challenging to observe aircraft at more congested altitudes. Flying at high speeds also leaves less time to take evasive action, even once visual contact is made.
Barometric altimeter information remains the primary altitude reference for complying with any altitude restrictions. WAAS equipment may not support LP, even if it supports LPV, if it was approved before TSO-C145b and TSO-C146b.
The “expect” altitudes/speeds are published so that pilots may have the information for planning purposes. These altitudes/speeds must not be used in the event of lost communications unless ATC has specifically advised the pilot to expect these altitudes/speeds as part of a further clearance.
Aircraft Holding Speed Limits – There is a maximum speed limit of 200 knots at 6,000 feet MSL and below – There is a maximum speed limit of 230 knots at 6,001-14,000 feet MSL – There is a maximum speed limit of 265 knots at 14,001 feet MSL and above

To ensure the safest and most efficient flow of air traffic, aircraft are bound by certain speed restrictions depending on altitude and terminal structure.
Class B. – When above 10,000 ft, there is no speed restriction inside Class B airspace. – When below 10,000 ft the speed limit is 250 knots. – There is a speed limit of 200 knots below the airspace or in a corridor.
Class C. – Unless otherwise authorized, there is a speed limit of 200 knots (230 mph) within 4 nautical miles and 2,500 ft of the primary airport of a Class C airspace area.
If a speed restrictions is published at Leoni, the aircraft will slow to comply with the published speed.
At uncontrolled airports, aircraft are expected to remain clear of clouds and complete a landing as soon as possible. If a landing cannot be accomplished, the aircraft is expected to remain clear of clouds and contact ATC as soon as possible for further clearance.
Whenever aircraft are holding, ATC will usually provide radar surveillance of the holding airspace on the controller's radar display . The controller will attempt to detect any holding aircraft that stray outside the holding airspace and will assist any detected aircraft to return to the assigned airspace.
Whenever an aircraft is cleared to a fix other than the destination airport and delay is expected , it is the responsibility of ATC to issue complete holding instructions (unless the pattern is charted), an EFC time and best estimate of any additional en route/terminal delay.
Overhead maneuver patterns are developed at airports where aircraft have an operational need to conduct the maneuver. An aircraft conducting an overhead maneuver is considered to be VFR and the IFR flight plan is canceled when the aircraft reaches the initial point on the initial approach portion of the maneuver.
When an aircraft is 3 minutes or less from a clearance limit and a clearance beyond the fix has not been received, the pilot is expected to start a speed reduction so that the aircraft will cross the fix , initially, at or below the maximum holding airspeed.
ATC must always issue complete holding instructions when pilots request them. If no holding pattern is charted and holding instructions have not been issued, the pilot should ask ATC for holding instructions prior to reaching the fix.
Ever wonder why there are varying speed limits and why obeying the speed limit is even important? Speed limits are set with the goal of keeping everyone safe. There is an inherent risk when driving a car – not just for the driver, but for others on the road (including passengers, other drivers, bicyclists, and pedestrians).
Driving at a higher speed increases your risk of losing control of your car while trying to adapt to changing road conditions. If you drive above the speed limit, keep in mind that you’ll need additional time to stop your car or react to changing road conditions safely. Posted speed limits do not dictate speed.
They are typically set on the basis of what 85% of drivers would comfortably drive on their own without posted limits. While states can set their own speed limits, the following general roadway guidelines apply in all states to help determine the speed limits:
Collector Roadways, such as County Roads, balance higher speeds, and more access points. Local Roadways, like neighborhood streets, have the lowest speeds due to the high number of access points.
In addition to enforcement by police, defensive driving is the key to safer driving. Reckless and aggressive driving is as dangerous and deadly as speeding and is the Number 1 cause of fatalities on our streets and highways. We see these drivers every day.
In fact, most motorists drive at a speed that is comfortable for them regardless of posted signs. But, coupled with law enforcement, speed limits and driving infractions for failing to adhere to the speed limit can create a safer driving environment for everyone.
Speed limit signs are placed along roads and highways to alert drivers to the maximum speed they are allowed to travel on that roadway. Speed limits are designed to enhance safety by reducing the risks created by drivers selecting the speed they wish to drive.
Without speed limits, drivers would be traveling at different rates , which would greatly increase the chance of a collision. Speed limits allow law enforcement to provide sanctions for drivers who choose to ignore the limits and endanger those around them.
When driving through a business district or near a school, a speed limit of 25 mph should be maintained. Residential areas typically have speed limits of 30 mph. The usual speed limit for open roads and local highways is 40 mph. Major highways generally have 65 mph speed limits and interstate routes have speed limits of 75 mph. ...
