Point of No Return.
It is the furthest point away from the departure aerodrome you can go and still come back to the departure aerodrome within the PNR endurance/Safe endurance.
Nowadays, they call PNR as PSR - Point of Safe Return.
Question for you guys:
What is Endurance?

Air Speed Indicator(ASI) is simply a dynamic pressure gauge which is calibrated to read in airspeed (knots).
Dynamic pressure = Total Pressure - Static pressure.

QDM - Magnetic bearing to the station.
QDR - Magnetic bearing from the station.
QTE - True bearing from the station.

A rhumb line is a curve that crosses each meridian at the same angle.
This curve is also referred to as a loxodrome (from the Greek loxos, slanted, and drome, path).
Although a great circle is a shortest path, it is difficult to navigate because your bearing (or azimuth) continuously changes as you proceed. Following a rhumb line covers more distance than following a geodesic, but it is easier to navigate.
All parallels, including the equator, are rhumb lines, since they cross all meridians at 90°. Additionally, all meridians are rhumb lines, in addition to being great circles.
A rhumb line always spirals toward one of the poles, unless its azimuth is true east, west, north, or south, in which case the rhumb line closes on itself to form a parallel of latitude (small circle) or a pair of antipodal meridians.
The above figure depicts a great circle and one possible rhumb line connecting two distant locations.
