Mental dump of questions for PPL & CPL level

FAR91.1119:

Except when necessary for takeoff or landing, no person may operate an aircraft below the following altitudes:
(a) Anywhere. An altitude allowing, if a power unit fails, an emergency landing without undue hazard to persons or property on the surface.
(b) Over congested areas. Over any congested area of a city, town, or settlement, or over any open air assembly of persons, an altitude of 1,000 feet above the highest obstacle within a horizontal radius of 2,000 feet of the aircraft.
(c) Over other than congested areas. An altitude of 500 feet above the surface, except over open water or sparsely populated areas. In those cases, the aircraft may not be operated closer than 500 feet to any person, vessel, vehicle, or structure.

The quote is from "From The Ground Up". I missed the "U".

Oh. Well, whassisname (we're not allowed to mention it, are we?) should know better, then.

The attachment is from the RIC-21: Study Guide for the Restricted Operator Certificate.

In this situation, when they say "all transmissions shall cease", are they referring only to the frequency in use by the aircraft in distress? Or are they banning all transmissions on ALL frequencies within the geographic area where the situation is occurring? Could other aircraft in the area switch to a different frequency in order to coordinate their actions....?

This question was still hanging out there. The SEELONCE only applies to the frequency where the emergency is being communicated/coordinated. If the stations involved in the emergency were to switch to another frequency, they would call for SEELONCE there as well. Other frequencies are unaffected.

. . . in this context when they say "license" they are not referring to something that is held by an individual person... they are referring to a license that allows the station to be operated by SOMEONE, regardless of who that someone is.....

The radio station is the airplane "radiotelephone". It's the hardware in the panel. That's not you, it's the airplane. You are the radiotelephone "operator", and you have a "Radiotelephone Operator Certificate (ROC)".

When he gets out of the plane, the Operator leaves the "radio station" behind, and goes home.

Ok so then it's not the RPM that determines whether or not the engine may get damaged - it's the %power?

Maybe it would help to study how airplane engines are certified. When an engine is certified as a "2000 hour" limited engine, it means that it has been tested over and over again in service, and the boffins have figured out (using statistics) that when run at NOT over the 2700rpm red-line with regular maintenance, that it will likely run reliably for 2000 hours without anything unexpected happening. It's a matter of probabilities. So exceeding 2700rpm isn't inherently "dangerous" (airplane racers run at 4000rpm+), it just means the engine's reliability is less. The airplane racer may only get 100 hours out of his engine before the crankshaft breaks. If you run your engine constantly at 2700rpm, you'll probably get 2000 hours out of it, or you might not. Your probability INCREASES if you run it more moderately, and decreases if you're more abusive. There's lots of undocumented patterns that will reduce the life of your engine, but this question was only about the 2700rpm red-line.
