What prevents RFI? - Answer-Grounding and bonding
BONDING JUMPER length - Answer-Bonding jumpers should be kept as short as
practicable, and installed so that the resistance of each connection does not exceed
0.003 ohm. The jumper should not interfere with the operation of movable aircraft
elements, such as surface controls; normal movement of these elements should not
result in damage to the bonding jumper.
Bonding and grounding surface prep - Answer-To be sure a low resistance connection
has been made, nonconducting finishes, such as paint and anodizing films, should be
removed from the surface to be contacted by the bonding terminal.
Bonding and grounding return current path - Answer-When bonding jumpers carry a
substantial amount of ground return current, the current rating of the jumper should be
adequate, and it should be determined that a negligible voltage drop is produced.
Bonding and grounding methods - Answer-Bonding and grounding connections are
normally made to flat surfaces by means of through-bolts or screws where there is easy
, access for installation. The general types of bolted connections are: a bolt or screw is
locked securely to the structure becoming a stud. Grounding or bonding jumpers can be
removed or added to the shank of the stud without removing the stud from the structure.
Nutplates are used where access to the nut for repairs is difficult. Nutplates are riveted
or welded to a clean area of the structure.
Bonding Straps - Answer-The electrical bonding straps between different components of
your airplane prevent static electricity build-up that can interfere with radio and
navigational equipment. More importantly, they provide lightning protection by allowing
current to pass through the airframe with minimum arcing.
Bonding straps- - Answer-Bonding straps must be installed across the instrument
mounts as a current path.
Bonding straps - Answer-Transfer electric charge due to static electricity or lightning
strikes back to the static wicks without damage to moving or sensitive parts (pivot
points, bearings, etc.).
Ground strips / Radome - Answer-Lightning diverter strips are located along the outer
surface of the radome to dissipate the electrical energy
Radome - Answer-Lightning protection is critically important for the long-term durability
of an aircraft radome, especially since composite components cannot handle the high
current and heat generated by lightning. During a preflight inspection these must be in
good condition. During both pre- and post-flight inspections check for any signs of a
"short" or disbonding of the strips from the radome.
radome - Answer-The protective covering of a radar antenna mounted on an aircraft.
Normally constructed of GRP honeycomb material and transparent to electronic energy.
Static wicks - Answer-Long, thin extensions installed on the trailing edges of aircraft for
the purpose of dissipating static electricity that can accumulate during flight by
discharging it into the air.
Bonding methods Direct Bond - Answer-Direct Bond: In this bonding type, specific areas
of members to be joined are placed in direct contact by permanent or semi-permanent
bonds. Permanent bonds are carried out using welding, soldering or brasing. Semi-
permanent bonds are carried out using bolted connections.
Bonding methods Indirect Bond - Answer-Indirect Bond: This type of bonding is used in
the applications where metal to metal contacts are not reliable to be used such as
where parts are frequently removed, parts which use dis-similar metal types, parts
which are exposed to corrosion or parts which will have relative motion such as hinges.
In this type of bond, other than primary bond with the help of mechanical joint, indirect
bond with the help of jumper wires is being employed.
