7.1-7.13 Flashcards
Examples of hazardous operation include, but are not limited to:
- Interfere with me and aircraft operations
- Operating an SUAS over people not directly participating in the operation
- Loading the SUS beyond its capabilities to the point of losing control
- Failure to consider weather conditions. Your structures trees are rolling, terrain, when in a densely populated area.
- Flying near emergency responders during a crisis
The FAA recommends flying at least ________________ horizontally, from skeletal structures, like radio and television antenna towers, to be clear of guy wires
2000 feet horizontally
Good judgment on the part of the pilot dictates that aircraft should remain well clear of all_________________ , and flight below them should be avoided at all times
Unmanned free balloons
High temperature exhaust plumes can cause significant air disturbances such as __________________ and __________________.
Turbulence and wind shear. Avoid exhaust flames as much as possible that come from smokestacks and cooling towers.
As ______________, you are ultimately responsible for breathing, the participants, your clients, your crewmembers, other ground, base, crew, etc. about emergency procedures.
Remote PIC
Part of preparing for an emergency is conducting a _________________ to understand the environment that you’ll be operating in
Site survey
A good site survey may include:
- local hazards, such as towers, powerlines trees, and other structures
- Check for radio interference that may compromise communication signals between remote controller and aircraft
- magnetic interference
- Traffic patterns that may be endangered by your operation
- non-participatory bystanders that may not be aware of what you’re doing
-Wind obstruction
Examples of situations that might trigger an emergency maneuver are:
Loss of orientation
Loss of GPS signal
Compass error
Loss of direct line-of-sight
Loss of video feed
Fly-away
Erratic movement
Structures in line of flight
Birds
One of the big things to know here is that you should always be prepared to switch to your aircraft’s _____________ mode during an emergency. That’s just a general best practice and, frankly, something that not enough pilots in this industry are comfortable doing.
Manual
Another general best practice in an emergency is that, after you’ve regained control, you should _______________________. Let the adrenaline wear off, analyze the situation, and then only if it’s appropriate to do so, get back in the air.
land safely as soon as possible and turn off your aircraft
Circular patterns of rotating air left behind the wing of a large aircraft as it generates lift. The __________________ are greatest when the aircraft is heavy, slow and developing full power, such as takeoff. In this case, the _______________ tend to sink below the aircraft generating turbulence.
Wingtip vortices
You’re flying an unmanned aircraft, and a helicopter enters your airspace. What should you do?
Yield the right of away to the helicopter
When using a small UA in a commercial operation, who is responsible for briefing the participants about emergency procedures?
The remote PIC
In any sUAS flight emergency, rule #1 is to:
Maintain control of aircraft
Wingtip vortices created by large aircraft tend to
Sink below the aircraft generating turbulence
The ____________________ frequencies are the unlicensed radio frequency bands that most UAS use for the connection between the control station and the unmanned aircraft.
2.4 GHz and 5.8 GHz
Both RF bands (2.4 GHz and 5.8 GHz) are considered ________________, and the command and control link between the CS and the small UA will not work properly when barriers are between the CS and the UA.
line-of-sight
To avoid frequency interference, many modern sUAS operate using a _____ GHz system to control the small UA and a _______ GHz system to transmit video and photos to the ground.
2.4
5.8
Use a safety bag or fire-proof container like a metal ammo box for charging, discharging, and storage for __________________.
LiPo batteries
They can cause fires. Just because your battery comes in a protective case doesn’t mean it’s safe. Your battery charging/discharging and storage area should be free from any materials that can catch fire, such as wood tables, carpet, or gasoline containers. The ideal surface for charging and storing LiPo batteries is concrete or ceramic.
Speaking of travel, do/do not travel with a LiPo battery in your checked baggage.
do NOT travel with a LiPo battery in your checked baggage. Use a carry-on.
If your battery is __________________, it’s done-zo. Make sure to follow proper disposal procedures and find a new battery ASAP.
damaged or puffy / swollen
LiPo batteries do not work well in _______ weather.
Cold
Your unmanned aircraft has been in an accident during a commercial flight, and during the accident your lithium battery was ejected from its compartment. You notice a small dent in the battery. What should you do before flying next?
Assess the extent of the damage. You might need a new battery.
Properly maintaining your LiPo batteries can increase their useful life by 3 to 4 times, saving you a lot of money throughout the course of your career as a remote PIC. Proper maintenance includes:
Avoid subjecting the battery to moderate to really cold temperatures
