Introduction
WARNING: To avoid injury, read all operating instructions and watch all online training
videos before flying
A small unmanned aircraft is defined in the ANO as any unmanned aircraft weighing not more
than 20 kg. A set of conditions are included at Articles 166 and 167 of the ANO subject to
which small aircraft may be flown without complying with airworthiness or flight crew
licensing requirements or with the Rules of the Air. These conditions include a prohibition on
flight in controlled airspace or within an aerodrome traffic zone unless in either case the
permission of the air traffic control unit has been obtained, a normal maximum height of 500ft
above the surface and a prohibition on flight for the purposes of aerial work without the
specific permission of CAA. Article 167 specifically covers the use of small unmanned aircraft
for surveillance or data gathering.
All Lehmann Aviation L-A Series drones are classed as light Unmanned Aerial System (UAS) for
capturing low level aerial images. They must be operated in accordance with the Civil Aviation
Authority regulations of your country. All L-A Series drones are certified by the French Aviation
Authorities (DGAC) for the flight scenario S2+.
Setting up aircraft
WARNING: Do not mount the Electronic part to the wing before the 5 seconds BEEP signal,
that will confirms that GPS satellites have been correctly fixed by the auto-pilot
WARNING: Always be careful with the propeller while manipulating the aircraft with the
battery connected. Make sure you keep the propeller far enough from your own fingers or
from any person around

7
WARNING: Never use L-A Series aircraft without mounting a GoPro camera in oblique or
vertical position (Hero3 and upper only). While using the vertical position mount for GoPro,
Canon or MicaSense camera, it is compulsory to mount a 50grams weight at the place of the
oblique camera mount (upper front of the wing), for balance purpose
WARNING: Always use a fully charged battery before each flight of L-A Series aircraft. Do not
accomplish 2 take-off with the same battery without re-charging it
Follow this procedure to set up your aircraft (quick launch procedure):
How to assemble the aircraft
1. Mount the camera in oblique or vertical position
- in vertical position, the balance weight should be in place in the front upper part of the
wing (at the place of the oblique GoPro mount):
2. Put your gloves on (right or left) to protect your fingers from the propeller at take-off

8
3. Connect on board battery: battery cable must be positioned as shown on the photo
below. Never mount the battery on the opposite side (with the cable going initially to the
front of the aircraft). Here is the good position of the battery and battery cable:
Once the battery is connected, the black part must be always kept horizontal. Do not move it
too fast till take-off in order to let the sensors calibration.
We strongly recommend to let the part on a stable place after you connect the battery (like
the ground or any table) where it will not move during OperationCenter connection and test
procedures.
4. Connect your aircraft WiFi (LA200 or LA300 network) to your Tablet:
- go on the “Settings” options on the right side of your screen

9
- and then click on the WiFi connexion icon. Default password is “password”
5. Open OperationCenter software
6. Click on the “Enable WiFi” button (“Connexion Successful”should appear. If not try again)
7. Go to the SYSTEMS page to check the aircraft systems (artificial horizon, GPS fix, date and
time):

10
Before going to the next step, wait for the GPS Fix (a 5s BEEP will come from the aircraft, the
red circle will disappear from the artificial horizon and GPS coordinates will appear on the
screen). GPS fix will be possible outside only. It will not fix inside offices, houses or
apartments.
- double check if the artificial horizon is moving well in the same direction when you are
moving the black part. You can also check the heading at this point.
8. Go to the NAV page and upload your flight path to the drone by pushing on the
“Import/Export” and “Send by WiFi” buttons (you can create a new one if needed):

11
9. Go to the FLY page
10. Mount the aircraft to the wing: be careful to put the battery cable inside the wing, and
do not let it outside as it may result in a poor efficiency of the Velcro attachment
- correct mount:
- incorrect mount:

12
- to have the black part and the wing assembled, you should “mount” the wing on the black
part. That means while always keeping the black part horizontal, you must place the wing on
top of the black part and not vice versa
- after “mounting” the wing on the black part, make sure that they are well aligned (keep the
aircraft horizontal during this process).
- correct alignment:
- incorrect alignment:
11. Check the 2 ailerons by tilting the aircraft 60° DOWN: the 2 ailerons must move in
opposite directions on a continuous basis. Your aircraft is now ready for take-off
WARNING: If 1 aileron doesn’t move correctly, you will have to do again all the setup
sequence. If the aileron is still not working after few attempts, then you will have to change
your wing. NEVER fly with an aileron malfunction.

13
Drone Update procedure
WARNING: Don’t update your system just before an important operational mission. Always
make a test flight after updating your drone before launching an operational mission.
WARNING: Always make an update with a fully charged battery. Don’t disconnect the
battery during the update process as it could needs your drone to be shipped back to the
factory to make it run again.
Update procedure
1. Connect your drone to OperationCenter (first WiFi hardware and then “Enable WiFi”)
2. Go to the LOGBOOK page and download all data from memory, if any
3. Export your LogBook file to have a backup of your flight logs
4. Go to the SYSTEMS page and make an “ERASE MEMORY”
5. Update OperationCenter, or un-install and re-install it from the Store
6. Check the version number (in the “Settings” and “Permissions” menus)
7. Connect your drone to the WiFi and open OperationCenter
8. If a drone update is available, OperationCenter will propose you to update your drone
automatically
9. Follow the update procedure
10. The process can take up to 3minutes. After uploading the new firmware, the aircraft will
begin the update process and aircraft leds will be switch OFF. They will turn ON again at the
end of the process. DO NOT DISCONNECT THE BATTERY before the end of the process.
11. When ended, you can disconnect the battery and reconnect it. Then open
OperationCenter and check if you need to import again your LogBook backup.

the controls, and more.
Flight Preparation
WARNING: Pre-flight preparation is essential in ensuring a safe flight
Flight preparation:
Require specific authorizations if needed (from field owner and/or Aviation Authorities)
Check weather conditions (1 to 3 days before operations and again the day of flight)
Charge all batteries (aircraft, camera, tablet/PC) and check all systems before leaving
Pre-Flight planning
1. Select a safe operation area (tall objects like trees or antennas must not be on the way of
take-off and landing)
2. Select a safe landing area (L-A Series aircraft can land on most of the surfaces but it is best
to avoid rough surface to prevent damage. Do not land on water)
3. Check wind direction and always take-off and land FRONT WIND. Otherwise, L-A Series
aircraft might not have enough power to climb properly during take-off, or can be damaged
at landing
