The problem is that there is no redundancy in the sensor input. The quote from the article is:
This original version of MCAS, according to two people familiar with the details, was activated only if two distinct sensors indicated such an extreme maneuver: a high angle of attack and a high G-force.
So on the original design, MCAS activation required two ...

The Boeing 737 MAX MCAS system is there ONLY to meet the FAA longitudinal stability requirements as specified in FAR Section 25.173, and in particular part (c) which mandates "stick force vs speed curve:, and also FAR Section 25.203 — "Stall characteristics".
FEDERAL AVIATION REGULATIONS Sec. 25.173 — Static longitudinal stability.
Sec. 25.173 — Static ...

Part 91 does not require an EGT probe for any operations so the next thing to look at is your AFM.
Your C172S has an AFM that includes a Comprehensive Equipment List. It is probably similar to this one that indicates that the EGT probe is standard equipment—not required for certification, this airplane can fly with it placarded.

You will need to pass the US commercial pilot test to remove the restriction. If you have enough hours, you may want to consider applying for an ATP certificate.
A couple of things are required to be completed.
Verify the authenticity of your foreign license through the FAA

Where noted, the information in this answer is from Advisory Circular 103-6, which was issued in 1983, but which apparently is not actually obsolete.
Is it possible to get the equivalent of flight following or at least call up ATC to let them know you are there, if you are planning on flying at higher altitudes? I am used to doing this for a D airspace if ...

When is a runway considered to be wet or slippery for 135 or 121 landing performance considerations?
I also could not find a definition for wet or slippery by the FAA, only for a contaminated runway:
CONTAMINATED RUNWAY− A runway is considered contaminated whenever standing water, ice, snow, slush, frost in any form, heavy rubber, or other substances are present. A runway is contaminated with respect to rubber deposits or other friction-degrading ...

As the Internet is a World wide communication medium, it should be noted what country's rules are being quoted. In Australia the rules for recreation aviation activities is governed by CASA (Civil Aviation Safety Authority). The general rule is 120 metres or 400 ft. AGL. and not within 5 km of airports and requires apecial approval with a zone and conditions ...

That's a completely incorrect understanding of the article. The summary should be:
MCAS activates if:
a) Sensor detects a high angle of attack
and
b) Sensor detects a high normal G load
If one sensor is erroneous and and the other one isn't, then MCAS would not erroneously activate.

From publicly available sources, the first motive of the MCAS was to satisfy the stick force per G requirements, or maneuvering stability (not static longitudinal stability, which deals with speed stability). This is confusingly captured in 14 CFR 25.255(b) and (c) under Out-of-Trim Characteristics, but also applies broadly to buffet characterization at mid/...

The MAX feels like the NG, which feels like the Classic, which feels like the -200. The flight control artificial forces are identical across the different versions, which share a type rating. No need for MCAS there.
Also, the MAX is longitudinally stable. MCAS was implemented for tackling some situations in extreme corners of the flight envelope, as ...

Beginning an instrument approach would mean being established on any segment of that approach, whether the initial, intermediate, or final approach segments, and they have received ATC clearance to do so.

When is a runway considered to be wet or slippery for 135 or 121 landing performance considerations?
The FAA does not appear to have issued a regulatory definition for wet or slippery, nor included such definitions in any current advisory circulars.
However, in addition to the information provided by @Bianfable, certain guidance has been provided which may be informative.
The original issuance of AC 91-79 (now superseded), Runway Overrun Prevention, ...

The only requirement is the height of the registration number, 12" if flying internationally (from the US anyway), 2" I think if staying domestic, and maybe new weight & balance - but usually a layer of paint and primer is taken off, and a new layer is put on, so the weight change is minimal. Any control surfaces that were removed may need rebalancing. ...
