PROGRESSION: MAINTENANCE TECH I II PRACTICE EXAM
2025/2026 QUESTIONS WITH SOLUTIONS GRADED A+
✔✔Which typical over-the-air signal sources can cause a false alarm with a signal
leakage detector? - ✔✔Typical sources include aircraft communication signals and
ham, mobile, and government radio broadcasts.
✔✔When adjusting or selecting the elements of a dipole antenna for measuring signal
leakage, what is the approximate length of each element relative to the wavelength of
the signal being measured? - ✔✔One-quarter wavelength.
✔✔Which of the following problem(s) are caused by egress? - ✔✔Interference with
aeronautical navigation and communication, amateur radio, public service, and cellular
communications.
✔✔What cumulative leakage index (CLI) meets Federal Communications Commission
(FCC) requirements? - ✔✔64 or less.
✔✔What is the maximum allowable signal detectable in the airspace during a flyover? -
✔✔10 µv/m.
✔✔CLI calculations do not include leakage below: - ✔✔50 µv/m.
✔✔Which of the following is a repair order specification when measuring leakage
levels? - ✔✔The location of the leak.
✔✔What is the FCC specification regarding repair of leakage of the 20 µv/m level?. -
✔✔There is no FCC specified time.
✔✔A dipole antenna is used for FCC tests because: - ✔✔Its performance is well
characterized.
✔✔What are the disadvantages of using an SLM for leakage detection? - ✔✔Less
sensitive than a leakage detector and doesn't have an alarm.
✔✔How long must the leakage log be kept on file? - ✔✔2 years.
✔✔What leakage level must be entered in the leakage log? - ✔✔Leaks 20 µv/m or
higher measured 10 feet from the cable.
✔✔In modern sweep systems, what type of nonintrusive and noninterfering test signal is
inserted into the downstream? - ✔✔Narrow-band continuous wave (CW) test carriers,
called pulses, at frequencies between channels.
