VLE vs. VLO Speeds: What's the Difference?
Understand the difference between VLE and VLO speeds, why landing gear speed limits matter, and how pilots avoid gear overspeed.
VLE and VLO are landing gear speed limits. They sound similar, but they protect different parts of the operation.
The short version:
- VLO is the maximum speed for operating the landing gear.
- VLE is the maximum speed for flying with the landing gear extended.
If you fly fixed-gear trainers, these speeds may not come up often. Once you move into retractable-gear aircraft, they become part of every takeoff, approach, and emergency briefing.
What VLO Means
VLO means maximum landing gear operating speed. It is the fastest speed at which you may extend or retract the landing gear.
The word "operating" is the key. VLO applies while the gear is moving.
Extending or retracting gear creates aerodynamic loads on doors, struts, linkages, actuators, motors, and hydraulic or electrical systems. Gear in motion is more vulnerable than gear locked in position.
Some aircraft publish one VLO for extension and another for retraction. Always check the POH or AFM for the specific airplane.
What VLE Means
VLE means maximum landing gear extended speed. It is the fastest speed at which you may fly with the gear down and locked.
Once the gear is fully extended and locked, it may be able to handle more airflow load than it can while moving. That is why VLE is often higher than VLO.
Do not assume that is always true. Use the numbers for your airplane.
Why the Difference Matters
Imagine you are being kept fast by ATC on downwind. You want to configure for landing, but the airplane is still above VLO. If you lower the gear anyway, you may overstress the system.
The correct answer is to slow first. Reduce power, level if needed, use approved drag devices if available, and do not move the gear until you are within the operating speed limit.
Now imagine the gear is already down and locked. You may be allowed to fly faster than VLO, up to VLE, because the gear is no longer moving. That can matter during a go-around, abnormal procedure, or pattern correction.
Where to Find VLE and VLO
Look in the POH or AFM limitations section. Also check cockpit placards and the landing gear control area. Some aircraft include landing gear speeds on checklists or quick reference cards.
Do not rely on memory from another aircraft. Even similar-looking retractable airplanes can have different speed limits.
If the airplane has both extension and retraction limits, write them clearly in your personal notes.
How to Avoid Gear Overspeed
Build a "speed check" habit. Before moving the gear handle, say or think: "below VLO, gear selected."
Plan descents earlier. Gear speed problems often happen because the pilot gets behind the airplane and arrives too fast.
Use configuration points. For example, you might plan to be below gear speed before entering the downwind, before the final approach fix, or before a specific distance from the airport. The exact technique depends on aircraft, airspace, and training.
Do not let ATC pressure push you into a limitation exceedance. If you need to slow, say unable or request a vector.
What If You Exceed a Limit?
If you accidentally exceed VLE or VLO, do not ignore it. Follow the aircraft checklist and maintenance reporting process. A gear overspeed can cause damage that is not obvious from the cockpit.
The safest pilots treat limitations as hard boundaries, not suggestions.
Simple Memory Aid
Use the letters:
- VLO: "O" for operating.
- VLE: "E" for extended.
VLO is about moving the gear. VLE is about flying with the gear out.
Training Scenario
Here is a practical way to brief it on downwind in a retractable airplane: "I need to be below gear operating speed before selecting gear down. Once the gear is down and locked, I still need to remain below gear extended speed."
That short brief catches the common mistake. Pilots sometimes remember that the gear can be down at a certain speed, then forget that the act of moving the gear may have a lower limit.
Learn both numbers before you fly a retractable aircraft. Gear systems are strong, but they are not designed for careless speed management.
