NCATT AET & AEIT Endorsement Exam Latest 2026 Updated
Questions and Verified 100% Solutions (2026/2027) Grade:
A+|Status: Guaranteed Pass -EMI, Grounding, Bonding, TSO,
PMA & Aircraft Wiring
Hardware Identification - Answers -AN - Air Force Navy Standard
NAS - National Aircraft Standard
What prevents RFI? - Answers -Grounding and bonding
BONDING JUMPER length - Answers -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 - Answers -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 - Answers -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 - Answers -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 - Answers -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- - Answers -Bonding straps must be installed across the instrument mounts as a
current path.
Bonding straps - Answers -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 - Answers -Lightning diverter strips are located along the outer surface
of the radome to dissipate the electrical energy
Radome - Answers -Lightning protection is critically important for the long-term durability of an
aircraft radome, especially since composite components cannot handle the high current and
