# 2. OPERATING LIMITATIONS
## **2.1 Introduction**
This Section includes operating limitations which are necessary for the safe operation of the Meadowhawk, motors, standard equipment and standard payload.
**WARNING**
All limitations given in this Section must be complied for all operations.
**NOTE**
Refer to the Supplements, Section 9 of this Remote Vehicle Flight Manual for amended Operating Limitations, Operating Procedures, Performance Data and other necessary information for the Meadowhawk equipped with specific equipment or payload.
## **2.2 Airspeed Limitations**
| | |
| --------------------------------- | ------ |
| Stall Speed | N/A |
| Operating Maneuvering Speed | 22 MPH |
| Maximum Structural Cruising Speed | 30 MPH |
| Never Exceed Speed | 38 MPH |
**NOTE**
Flight speeds and flight envelope are limited by flight controller factory settings. Wind speeds may affect these values.
## **2.3 Mass | Centre of Gravity Limits**
| | |
| ------------------------------------------------------------------------ | --------------- |
| Empty Weight - Without Flight Battery or Payload | 4 lbs / 1.8 KG |
| Nominal Take-Off Weight - with Standard Flight Battery, Standard Payload | 7 lbs / 3.1 KG |
| Maximum Take-Off Weight | 10 lbs / 4.5 KG |
**WARNING**
Exceeding weight limitations may lead to overloading of the Meadowhawk structure and cause loss of control of the Meadowhawk and/or structural damage.
The reference datum for determining the longitudinal Centre of Gravity is located below; given the lateral symmetry of the Meadowhawk, the reference line for the lateral Centre of Gravity is located on the symmetry axis.
**WARNING**
Exceeding the centre of gravity limitations reduces the maneuverability and stability of the Meadowhawk.
**NOTE**
The values are based on simulations and are verified during D\&R

**Forward/Aft**
### **2.3.2 Lateral Centre of Gravity Limits**
**Left/Right**
## **2.4 Flight and Maneuver Limitations**
## **2.5 Flight Battery Limitations**
| | |
| ------------------------------- | ---------------------------- |
| Approved Types of Batteries | Union Robotics® Li-ion 14 Ah |
| Minimum Operation Voltage | 17V |
| Recommended Operation Voltage | 25.2V |
| Maximum Number of Charge Cycles | 200 |
## **2.6 Weather Limitations**
| | |
| --------------------------------------- | ------------------------------------------------------- |
| Do not fly Meadowhawk in temperatures | Exceeding 45°C(113°F)
or Below -20°C(-4°F)
|
| Do not fly Meadowhawk in wind exceeding | 20 MPH |
| Do not fly Meadowhawk in weather | Snow, Rain, Fog |
**NOTE**
The values are based standard flight conditions and will be updated upon our D\&R
## **2.7 Range and Endurance Limitations**
### **2.7.1 Flight Battery**
| | |
| ----------------------------------- | ----- |
| Total Capacity | 25.2V |
| Do Not Fly Meadowhawk Battery Below | 17V |
### **2.7.2 Command and Control Link**
| | |
| ---------- | ------------------------------------------------------------------- |
| Max. Range | 10 km / 6.2 mile
(unobstructed, free of interference)
|
## **2.8 Kinds of Operation**
As governed by the U.S. Federal Aviation Administration, sUAS flights are limited to Visual Line-Of-Sight (VLOS) flights, under Day Visual Flight Rules (VFR) conditions.
