PERFORMANCE
FLIGHT TIMES
o
The AV is designed to hover at high efficiency. Hovering is much less efficient than flying on
a wing, thus flight times are low compared to fixed wing aircraft.
o
All the weight of the AV is supported by power from the batteries. As the batteries are used in
a flight, the amount of power available decreases. Therefore the power reserve is constantly
decreasing as the battery is being used. Thus loading a rotorcraft above its limit is not
recommended. While the AV may have enough power to lift off initially on a full charge, the
power reserve at partial charge may be too low to allow for maneuvering and will result in a
crash.
o
High lateral speeds will add lift to slightly improve efficiency. The rotors act similar to fixed
wings at higher speeds. This increase in efficiency may be negated by the increased power
consumption of forward flight.
o
High winds or gusts decrease efficiency/flight time. The motors work harder to hold position.
o
As weight increases flight times decrease.
WIRELESS TRANSMISSION
o
Refer to the specific manuals for performance ratings.
o
Wireless communications utilized provide acceptable communication for LOS.
o
In general:
LOS is required
The higher the GCS antennas, the better the range
Any freq. at may have severe degradation due to location to other admitters such as
cell towers
RSSI (Received Signal Strength Indication) should be monitored for indication of
communication drop out.
