# Before You Fly

### You are fully responsible for operating safely and legally. 

You must follow:

* Local aviation regulations
* Airspace restrictions
* Safe flight practices

{% hint style="warning" %}
**Important Safety Note:** Obstacle avoidance is disabled when flying with the Spexi app. As a pilot you must maintain situational awareness at all times and avoid obstacles manually during Spexi Flights.
{% endhint %}

### **Taking Back Manual Control**

You can immediately regain control of your drone by:

* Pressing the Return-to-Home (RTH) button on the controller
* Switching the mode on the controller


* Pulling down on the left power stick

### **How Missions Are Designed for Safety**

Missions are designed to work within the current civilian aviation regulations and best practices that all airspace pilots must follow. There are three main network design decisions to help ensure safe operations:

#### Airspace 

Missions should not appear:

* Near take-off and landing areas of airports/aerodromes


* Over restricted airspace (CYR areas, prisons, military bases)

#### Flight Altitude

Missions capture imagery at: 80 meters (\~260 feet) above ground level (AGL) with terrain following enabled. This provides optimal image resolution while remaining safely below the 400-foot regulatory limit.

#### Visual Line of Sight (VLOS)

Spexigons are sized at approximately 25 acres so missions can be flown within visual line of sight.

At all times, pilots are meant to act as the primary Detect and Avoid (DAA) function. This ensures pilots can make an emergency descent or maneuver in the unlikely event a manned aircraft enters their vicinity.
