Keel beamTransverse beamBox beamAll 7 Structural fuse Prevents primary structure damagePrevicts shear loadsPrevents overflow of current in the circuitAs in a & c 8 When the temperature is more than standard value, the TAS will be HigherLowerFirst & then remains with effectedRemains inaffected 9 Strain is measured by Original length divided by change in lengthForce by areaPressure multiplied with change in lengthUnit distortion of body 10 A solid metallic sound in coin tap test of honeycomb structure indicates : Core damageFacing damageFacing & core damageSeparation of layers in honeycomb constructions 11 Smoke clearance system is used with Fire protection systemPneumatic systemsAs in b and a pre-set temperatureNone 12 To avoid tip stalling & making the aileron effective for complete flight, wing is provided with was out, wash out means Incidence is angle is greater at wing tip than wing rootIncidence angle is greater at wing root than wing tipWing tip is a located ahead when componed to wing rootNone 13 Under inflation is indicated by Shoulder wear out in the tyreMore tread wearHigh brake heatNone 14 Static discharge damage is identified by Pits on the surfaceWing tips & trailing edges are damagedWing tips & trailing edges are damagedUsually found at wing tips, trailing edges & antennas 15 When proper jigs are not available, the smoothness of center of the a/c wing is measured by Applying Vaseline & cellulose paperUsing a thin cord along the leading edge to trailing edge parallel to the line of flightVeins a thin cord long the lending edge to trailing edge parallel to the lateral axisBoth a & b 16 Purpose of surge tank is It protects tank structure damageIt allows fuel to flow into the tank which is at a laterally lower levelIt collects over flowing fuelAs in b & c 17 Mark the correct statement Damage of nose cone does not affect flt of an a/cDamage to secondary structure like wing tip & nose cone does not affect the flt of a/cDamage to seat & seat supporting structure affect flightNone of the above 18 Mark the correct statement regarding reynold's number If the Rey's no is high then kinematic velocity is highHigher the Rey's No. , higher the kinematic viscosityHigher the Rey's No, smaller the kinematic viscosityHigher the Rey's No. smaller the kinematic viscosity & velocity 19 Mark the correct statement Steel & magnesium is used for secondary structural membersIberglass & magnesium is used for secondary structural membersAl honey comb & fiberglass honey comb structure is used for secondary structural memberAl is used for a particular type of lead only 20 Turn & slip indicator measure The amount of tumThe rate of tumIn slip the amount of tum is too lowIn skid the amount of tum is too high 21 The station number is distance in enhance from A yew reference point forward of fuselageReference point on the nose tipReference point at wing of empty a/cReference point at the most forwarded C. G point of empty a/c 22 Inboard & king of taper rolled provide Max thickness area of heavy loadingMin thickness area of reduced loadingThickness skin at root and across fuselage.Thickness at high tort ional loads 23 Plate between front and rear span Has thickness taperedIs butt splicedHas tapered thickness and is but splicedHas tapered thickness with flush fastness 24 Artificial Horizon Has a complete freedom 360° in roll and 85° freedom input is hat it is difficult But not impossible topple the horizonHas a wonder rate of gyro less than 15° per hourHas a gyro axis titled forward about 15° to compensate to rate of turningAll the above are correct. 25 If a/c alternates on easterly heading the compass will indicate Apparent turn towards northApparent turn towards southDoping of compassNone of the above. 26 Rate of climb indicator is A different pr gauge to indicate rate of altitude changeNot a D pr gauge sime operation depends upon static programmeHaving, is most cases, a logarithmic scale as it is advantageous in start & statementEffected by position error 27 Rate of climb indicator Has two springs for selling range, which bears on stem connected to center piece.With range setting spring to extent force of capsule to achieve relation between capsule pr deflection characteristicHas spring screws the upper row of screws to upper row of spring control rate of decent calibrationAll above the are correct 28 Dip magnetic compass Is caused by the horizontal component of earths magnetic fieldIs called by vertical component of earth magnetic fieldIs max at equator & min at polesBoth a & b are correct 29 When automatic control is selected in electro HYDRAULIC auto pilot system The engage com is out of detentEngage signal is fed to the 5. 0 voltsA & bPilot control valve is operated 30 When control wheel is released in control wheel sterling the automatic control Holds a/c at originally selected altitudeIs provided by a pilot & Roll forces simultaneously pilot through force transactionsHolds the a/c a newly established altitudeBoth b& c correct A mistake in this Quiz ?
