A "Bourdon tube" is used in:
To indicate a temperature, a thermocouple requires:
Given: E = electromotive force (emf), Tc = cold junction temperature, Th = hot junction temperature, K = constant. The relationship that applies to a thermocouple is:
When, in flight, the needle of a needle-and-ball indicator is on the right and the ball on the left, the aircraft is:
In computer technology, an EPROM: 1) is a read-only memory 2) is a write memory 3) erases its content when power supply is cut off 4) keeps its content when power supply is cut off. The combination re-grouping all the correct statements is:
For an installed EFB host platform used for on-board documentation, which statement about its operating system is correct under EASA AMC 20-25A?
Which of the statements about computer architecture are correct or incorrect? 1) The software part includes the programs that make up the operating system (OS). 2) The hardware part includes the physical components of the computer.
What is the name of an evacuated, sealed flexible diaphragm capsule used to sense absolute pressure, such as in a conventional aircraft pressure-measuring instrument?
An aircraft indicates 16 000 ft with the correct current QNH set, referenced to a sea-level datum. The outside air temperature is -30°C. Assume ISA temperature decreases by 2°C per 1000 ft, the ISA temperature deviation is constant throughout the layer, and instrument and position errors are negligible. Using the approximate 4%-per-10°C temperature-correction rule, what is the true altitude?
Hard iron magnetism in aircraft may be caused by:
