Where do I usually find the tolerance of the leak rate for a large airplane pitot static system?

Damage may occur to other aircraft instruments, such a s the vertical speed indicator (VSI), if the altitude rate changes than the limit of the installed instrument

Those instruments directly applicable to the immediate control and navigation of the aircraft are defined as what type of instruments?

What is the purpose of the Comparator Function of the EFIS system?

These are a set of regulations that dictate how aircraft are to be operated when the pilot is unable to navigate using visual references.

What is the purpose of Powerplant instrument (display) range marking?

What are some of the precautions to be taken when carrying out a compass swing?

At minimum how often do you perform a compass swing?

What can a technician use to check for free card movement before a compass swing and only if symptoms of a fault do exist?

What are the measurements of a Standard Day?

These are located above or below the main sensor magnets.

Who is allowed to sign a Green Serviceable Tag?

At the Earths magnetic Equator the magnetic lines of flux are parallel to the surface. Everywhere else there is also a component pointing toward the surface.

What required paperwork MUST be shipped with the unserviceable component?

When doing a compass swing you would remove all the error on these two headings and then half the error on these two headings and

On a compass swing the aircraft is aligned on each magnetic heading and the compensating magnets are adjusted to the difference between the compass indication and the actual magnetic heading of the aircraft.

This Pitot/Static test instructs you to tap around the case of the instrument (not the glass) to see if the vibration will cause a change in the indication.

The purpose of this analyzer is to functionally check the aircraft EGT system for error, without running the engine or disconnecting the wiring.

Deviation, unlike variation, is on each heading, but it is not affected by geographic location

The 3 main instruments that use the pitot-static system of the aircraft are what?

To find the leaks of an altimeter air system, ensuring that the there is positive pressure, apply a mild soap solution to the fittings or air lines to identify leak and see if it bubbles because the air will leak out.

What type of screwdriver should be used when adjusting the compensating screws on a compass?

This occurs because the compass card CG is located BELOW the card’s suspension point

The EFIS system goes into this mode automatically if a display failure is detected.

Upon completion of a compass swing, we align the aircraft every ___ degrees to record the deviation

This Pitot/Static test tests at a constant atmospheric pressure and changes the barometric setting?

What does RVSM stand for

What is the difference between Variation and Deviation?

In order to make it obvious, the tape must be removed after test completion of a Pitot/Static check.

Which system can a technician turn on from the EFIS control panel (for example, Boeing 737 NG)?

On a Thermoelectric temperature sensing, where is the cold junction?

What is the effect when two junctions are maintained at different temperatures

What pressure(s) does an Air Speed Indicator (ASI) require to operate?

What is the purpose of the Kollsman window?

Deviation in excess of degrees must be maintained by checking for local magnetic effects

What must be done to the compensating magnets before a compass swing

True Altitude is the vertical distance of your airplane above what reference?
