RNAV is Radio Navigation ("nav"). It is a form of electronic navigation that uses DME and other signals to form a point in the distance that an aircraft can fly to even though there is no actual signal coming from that point.

What does VGSI and RNAV glidepath not coincident mean?
VGSI is the visual guidance (VASI or PAPI) and RNAV is the electronic guidance on an instrument approach. When the VGSI and RNAV glidepaths are not exactly the same, it is said that they are not coincident.

What is the Blue federal airway on the VFR terminal area chart?
Class E airspace at low altitude federal airways are indicated by center line. Intersection-arrows are directed towards facilities which establish intersection. Class E airspace at low altitude federal airways are indicated by center line. Intersection -arrow are directed towards facilities which establish intersection. Class E low altitude RNAV 2 routes are indicated by center line.
What is the abbreviation of intersection?
intersectionAs the circumstances require, this may be(a) a point on the surface of the earth over which two or more position lines intersect. The position lines may be true bearings from non-directional beacons (NDB) (magnetic bearings shown on charts for pilot usage); radials from VHF/UHF NAVAIDs; centrelines of airways, fixed RNAV routes or air routes; localizers; or DME distances; or(b) the point where two runways, a runway and a taxiway, or two taxiways cross or meet.abbreviation: INTXNFr: intersection

Is radar and radio navigation the same thing?
They are VERY different. Let's start with RADAR first. Radar sends out a high frequency signal from an antenna located at the base of the radar device. The signals goes out, at the speed of light, and bounces off of any solid object it encounters. The antenna at the radar station now will receive this bounced back signal. The signal will have had a slight phase shift associated with it This shift cooresponds to distance. The strength of this signal will be determined by the density of the object the signal bounced off of. The quality of the receiver determines how thin or small a signal is processed. It takes a great receiver for rain and weather, for example. Radio Navigation is much different. Land based transmitters are located throughout the world. For us pilots, we use systems that transmit in the 110 Mhz range. These stations are based a few hundred miles apart and send out signals that we can follow to and from these sites. These transmitters are called VORTACs. These VORTACS sometimes also send us other information, including weather. Before VORTACs, we had a system called ADF. These systems used AM radio stations and other transmitters in the 700 Khz range. They could be heard much further but did not offer quite the accuracy of VORTACs. Today, a newer form of navigation system is making all of these obsolete. This new system is a Radio Navigation system called GPS. Global Positioning Systems use several satellites in what is called a polar coordination system. Three satellites must be used to determine where you are exactly and the height you are at. It really gives us two possibilities, but one is many miles above the planet, so we mathmatically remove that choice. GPS systems only know how far you are from there position and the exact time and there exeact position for that time. As a result two satellites give us four possible positions (two logical and two way too high). This is why we must have three to be useful. Bottom line is Radar uses a single transmitter located in the system. Rnav systems use external transmitters that we use for position.
