A 24 volt lead-acid battery has how It has 12 cells, and each cell is rated at 2 volts
many cells, and what is each cell
rated at?
AC fluid line fittings have a flare 35°
cone angle of what?
Briefly describe the procedure for 1) Thoroughly clean all grease, oil and dirt from
performing a magnetic particle the part, part must be of ferrous material ex
inspection. iron or steel. 2) magnetize the part and then
apply the ferromagnetic particles, either held in
liquid suspension or in dry powder form, to the
area to be inspected. 3)If a discontinuity is
present, the magnetized particles will form a
pattern in the approximate shape of the
discontinuity.
Can Lead acid and Ni-cad batteries No, the fumes from the lead acid battery can
be stored together? contaminate the electrolyte in the Ni-cad
battery.
,Define "Clearance" as used in aircraft This is the dimension given for the space
drawings. between parts.
Define "Tolerance" as used in aircraft The difference between the plus and minus
drawings. allowable dimension of a part. (± of .005
=.010)
Describe a no-trip (trip-free) circuit this type of breaker makes it impossible to
breaker. manually hold the circuit closed when excessive
current is flowing through the circuit. (the
breaker pops when the circuit gets hot, and
cant be reset until the circuit has cooled off.)
Describe the system used to For fuels below grade 100, octane numbers are
designate performance rating of used, such as 91/96. The fuel is compared with
aviation gasoline. mixtures of iso-octane and normal heptane.
Thus , grade 91 fuel has the same knock
characteristics as a blend of 91 percent octane
and 9 percent hexane. When two numbers are
used, the firtst number is the lean mixture
performance rating, while the second number
is the rich mixture performance rating.
For fuels above grade 100, the numbers
represent the performance rating of the fuel
compared to 100 percent Iso-octane. That is,
its knock-free power available as compared
with that available with pure iso-octane.
AN fluid line fittings have a flare 37°
cone angle of what?
, Give examples of perfect square 4, 9, 16, 64, 100, 144, etc.
numbers.
How are battery compartments They are coated with special corrosion resistant
protected from against corrosion? paint such as a bituminous paint, an asphaltic
(tar based) paint, or with polyurethane enamel.
How are standard AN type and AC AN fluid lines are either blue or black, while AC
Type fluid line fittings identified? fittings are usually gray or Yellow. AN fittings
have coarser threads and they have a small
shoulder between the threads and the and the
flare cone. AC fittings are threaded all the way
down to the flare cone.
How can a change to an aircraft By it's revision letter (A,B,C, etc). the revision
drawing be identified? letters are usually listed in a table next to the
title block, or in the corner of the drawing.
How can the correct "grip length" of Grip length should be equal the total thickness
a bolt be determined? of the material being bolted together.
How can the correct torque for a Standard torque table should be used as a
bolt be determine? guide whenever specific torque values are not
called out in the manufacture procedures.
how does a quick disconnect each half has a valve that is opened when
coupling work? coupled together, and are spring loaded to
close when disconnected.
How do you divide one fraction by multiply the 1st {numerator/denominator }by
another? the 2nd fractions {denominator/numerator}. ex.
(a/b) ÷(c/d) = (a/b) x (d/c)
