A sudden drop in the vacuum gauge reading in a maintenance scenario often indicates failure of which component?
Pitot tube
Flap actuator
Vacuum pump
Altimeter
The vacuum gauge measures pressure drawn by the vacuum pump; a sudden drop typically points to pump malfunction or failure.
Given an aircraft weight of 5,000 pounds, wing area of 200 square feet, air density of 0.00237 slugs/ft³, and cruise speed of 150 knots (253 ft/s), what is the required lift coefficient (Cl)? (Use L = Cl - 0.5 - ϝ - V² - S)
0.25
0.33
0.15
0.45
Substituting L=5000, ϝ=0.00237, V=253 ft/s, S=200 ft² into the lift equation gives Cl ≈5000/(0.5 - 0.00237 - 253² - 200)≈0.33.
What is the primary function of the pneumatic de-ice boot system on wing leading edges, and what certification standard must it meet?
Hot bleed-air panels and must meet FAR Part 25
Electric heating coils melt ice and must meet TSO-C14
Inflatable rubber boots break ice accretions and must meet TSO-C18
Chemical spray anti-ice and must meet STC only
Pneumatic de-ice boots inflate to crack off accumulated ice and are certified under TSO-C18 or equivalent to ensure reliability in icing conditions.
During a borescope inspection of a turbine engine, what indication typically signifies a fatigue crack in a compressor blade?
Excessive debris in the oil filter
Uniform discoloration across the blade surface
Coating wear on the trailing edge only
Fine linear hairline cracks emanating from the leading edge
Fatigue cracks often appear as fine, linear hairline defects beginning at stress concentration points on the blade leading edge.
How does partial icing of the static port affect airspeed and altimeter readings?
Airspeed reads erratically high in climbs and low in descents; altimeter freezes at a constant reading
Airspeed drops to zero; altimeter remains accurate
Airspeed unaffected; altimeter overreads slowly
Airspeed underreads in all flight phases; altimeter underreads
Blockage of the static port traps a constant pressure in the system, causing the altimeter to freeze and airspeed to vary inaccurately with vertical movement.
What is the difference between a Type Certificate (TC) and a Supplemental Type Certificate (STC) regarding aircraft modifications?
TC applies to individual serial numbers; STC applies to whole fleets only
TC is only for engines; STC is only for airframes
TC approves original design; STC approves specific modifications not covered by the original TC
STC replaces the TC when new models are produced
A Type Certificate validates the original aircraft design, while an STC authorizes specific aftermarket modifications that the original TC did not include.
