You’re on final approach, airspeed bleeding off, and the runway is rushing up. You reach for the flap lever, but nothing happens. Or worse, you pull it too late and the aircraft bucks. If you’ve ever felt that panic, you’re not alone. Getting the flaps right in the ToLiss A320 is one of the most common hurdles for sim pilots. Let’s fix that right now.
This guide shows you exactly how to set flaps on ToLiss A320, step by step, with the real-world logic that Airbus pilots use. No fluff, no theory that doesn’t matter. Just the actions you need to take in the cockpit.
Why Flap Settings Matter in the ToLiss A320
Flaps change the shape of your wing, increasing lift at lower speeds. But they also add drag. The A320 has five flap settings (0, 1, 2, 3, FULL) plus a detent for CONF 1+F. Each setting has a specific speed range. If you go too fast, you risk structural damage. Too slow, and you stall. The ToLiss A320 simulates this faithfully, so you need to respect the numbers.
Before you touch the lever, understand that the flap lever on the overhead panel controls the slats and flaps together. The system is automated, but you must select the correct position based on your flight phase.
Flap Lever Positions and Speed Limits
| Flap Setting | Slats | Flaps | Max Speed (VFE) |
|---|---|---|---|
| 0 | Retracted | Retracted | N/A (clean) |
| 1 | Extended | Retracted | 230 kts |
| 1+F | Extended | Extended (partial) | 215 kts |
| 2 | Extended | Extended | 200 kts |
| 3 | Extended | Extended | 185 kts |
| FULL | Extended | Extended (max) | 177 kts |
These speeds are hard limits. The ToLiss A320 will flash a warning and can damage the flaps if you exceed them. Always check your PFD speed tape for the amber VFE marks.
Step 1: When to Start Extending Flaps
You don’t set flaps on the ToLiss A320 until you’re on the approach. The standard procedure is to extend flaps at specific points in the descent. For a normal ILS approach, you’ll typically start at 10-15 nautical miles from the runway, with the aircraft at 250 knots or below.
Press the FLAP lever on the overhead panel. The lever has a mechanical detent feel in the ToLiss. Pull it down to position 1. Watch the ECAM to confirm slats extend. You should see the flap indicator on the upper ECAM move.
Step 2: Select Flap 1+F or Flap 1?
This is a common point of confusion. The A320 has two different ‘1’ positions. If you select flap lever position 1 when your speed is below 210 knots, the system automatically extends flaps to 1+F (slats + partial flaps). Above 210 knots, only slats extend. In the ToLiss, you can override this, but for normal operations, let the aircraft decide.
For your first time, keep the speed around 200 knots when you select position 1. You’ll see both slats and flaps deploy. That’s fine.
Step 3: Progress Through Flap Settings
As you slow down further, you’ll select each flap position in order. The general rule: select the next flap setting when your speed is below the VFE for that setting minus a small buffer. For example, when you’re below 200 knots, you can select Flap 2.
- Select Flap 1 (or 1+F) at around 210-220 knots.
- Select Flap 2 when speed drops below 200 knots. Usually at the glide slope intercept.
- Select Flap 3 when speed is below 185 knots. Typically on final approach, around 4-5 miles out.
- Select Flap FULL when speed is below 177 knots. This is done just before the final approach fix, usually at around 1000 feet AGL on a normal approach.
In the ToLiss A320, you can use the mouse wheel to scroll the flap lever, or click and drag. The lever moves smoothly. The ECAM flap indicator will show the current position in green.
Troubleshooting Common Flap Problems
Flaps Not Moving
If you pull the lever and nothing happens, check the hydraulic systems. The ToLiss A320 needs hydraulic pressure from the Green and Yellow systems for flap operation. Ensure both engines are running (or APU is powering the hydraulics). Also, check the FLAP CONTROL switch on the overhead panel. It should be in NORM. If it’s in OFF, you won’t get any movement.
Flap Overspeed Warning
If you hear a repetitive ‘cricket’ sound and see a red ‘FLAP OVSPD’ message on the ECAM, you’re too fast. Immediately reduce thrust and slow down. The ToLiss models structural damage if you persist. To avoid this, always monitor the VFE speed tape marks.
Flap Asymmetry
If one flap doesn’t match the other, the ECAM will show a ‘FLAP ASYM’ warning. The ToLiss A320 will automatically stop the flaps. You need to manually override with the FLAP CONTROL switch to set them to a safe position. For a sim, simply recycle the flaps by retracting to the previous position and trying again.
How to Set Flaps for Takeoff
Takeoff flaps are different. The standard setting for the A320 is CONF 1+F (or sometimes CONF 2 for short runways). In the ToLiss, before takeoff, set the flap lever to position 1. The aircraft will configure 1+F. Check the ECAM to confirm slats and flaps are extended. Then follow your takeoff speeds (V1, VR, V2). After takeoff, at around 400 feet AGL, you can retract flaps: select position 1, then 0, as you accelerate.
Do not retract flaps too early. Wait until you reach the appropriate speed (typically above clean maneuvering speed, which is around 210 knots).
Common Mistakes and How to Avoid Them
- Selecting FULL too early: This adds huge drag. Wait until you’re on final approach, speed stable below 177 knots.
- Forgetting to retract flaps after go-around: If you go around, immediately set flaps to 1 or 2 (depending on speed) and then retract gradually.
- Ignoring the ECAM flap indicator: The graphical display shows exact position. Use it.
- Using mouse wheel too fast: The ToLiss lever is sensitive. Scroll slowly or click to avoid overshooting.

Final Checklist for Flap Settings
Before you fly, run through this quick list. It will make how to set flaps on ToLiss A320 second nature.
| Phase | Action | Speed Check |
|---|---|---|
| Takeoff | Set lever to 1 (1+F) | Below 210 knots |
| Climb | Retract to 1, then 0 | Above 210 knots |
| Descent | Set 1 at 10-15 NM | Below 230 knots |
| Approach | Set 2, then 3, then FULL | Respect VFE each step |
| Go-Around | Set 1 or 2, retract after | Accelerate above VFE |
Practice this sequence on a few VFR patterns. You’ll build muscle memory and never second-guess your flap settings again.
Frequently Asked Questions
Why won’t my flaps deploy in the ToLiss A320?
Check the hydraulic pumps. If both engines are off and the APU is not running, the flaps won’t move. Also verify the FLAP CONTROL switch on the overhead panel is set to NORM. Finally, ensure the aircraft is not in a high-speed condition that prevents flap extension.
What is the difference between CONF 1 and CONF 1+F?
CONF 1 extends only slats. CONF 1+F extends both slats and a small amount of flaps. The aircraft automatically selects 1+F when the lever is in position 1 and speed is below 210 knots. Above that speed, only slats extend.
Can I use the keyboard to set flaps in the ToLiss A320?
Yes. By default, the ‘F’ key cycles flaps up/down in X-Plane. However, the ToLiss A320 uses custom logic. It’s better to use the mouse on the overhead panel lever for precise control. Keyboard assignment can cause unintended overshoots.
What speed should I use for flap retraction after takeoff?
Wait until you reach the ‘clean’ maneuvering speed, usually around 210 knots. Then retract from 1+F to 1, then to 0. Follow the FCOM speeds for your specific weight. The ToLiss A320 PFD shows the green dot speed for reference.
Does the ToLiss A320 model flap damage?
Yes, it simulates structural damage if you exceed VFE speeds repeatedly. The ECAM will show a warning, and the aircraft may handle differently. To avoid damage, always respect the speed limits shown in the table above.
