Routine Maintenance - YUNEEC H520 Maintenance Manual

ROUTINE MAINTENANCE

before flying / everytime)
(
Yuneec recommends that you take off and land on clean, level ground surfaces. Dust, dirt, sand,
leaves, and other light particles can cause Foreign Object Damage (FOD), shortening operating time
and causing sudden aircraft failure during flight operations. Take off and land on a clean surface,
e.g. on a clean concrete, wood or plastic surface or on a dry textile. For take-off and landing, a clean
take-off and landing space should be used. It should be made of a heavy material and secured so
that the side edges are not raised by the downdraft. Make sure that the take-off and landing area
provides sufficient space for the landing gear and the downdraft caused by the propeller.
Never take off directly from a sandy, soft soil or a dirty concrete surface.
Aircraft
Make sure that: the engines are turning smoothly; the battery is fully charged; the battery is
completely located/locked in the flying frame; the propellers are locked on the engine;
the propellers have no dents, cuts or other damage (replace if necessary);
the propellers are symmetrically arranged (if necessary, replace); the landing gear is at the
appropriate angle;
the gimbal is properly attached to the pin rails;
the gimbal vibration dampers are seated correctly and secured with the pins; the camera is
completely free of movement.
If the aircraft is more than 8 kilometers from the last calibration, recalibrate the compass / GPS.
ST16S ground station
Make sure that: the remote control is fully charged; at least 7 satellites for the aerial antenna (s) are
permanently attached; the openings are not blocked.
For each flight, always keep the unmanned aircraft about half a meter above the ground (so that it
does not fly at eye level) and then check that it is properly controlled.
Before starting the job, check the forward/reverse/down/up/down and yaw functions.
