# 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

## **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.
