NOTAMs, Pirep, Airmet, Sigmet

Notam:

A notice to airmen (NOTAM) is a memo that informs pilots of important updates and potential hazards to note for a specific flight – anything from nearby construction cranes to rocket launches.

Pirep:
Pilot reports (PIREPs) are the only direct source of information on cloud heights, turbulence, visibility, winds and icing between weather reporting stations and at some airports. They’re particularly important on flights below 10,000 feet.

Submitted by pilots from situations in the air.

Can be submitted in the air, there's phraseology for that:

Airmet:

Information message issued by a meteorological watch office (MWO) to advise pilots of the occurrence or expected occurrence of specified weather phenomena which may affect the safety of aircraft operations, which were not already included in a Graphic Area Forecast (GFA), and the development of those phenomena in time and space

VNC / VTA, Lambert and Mercator, Arc of great circle, Rhumb Lines

Image
 VNC and VTA maps are owned by nav canada.  This pdf shows current version and next planned update: https://www.navcanada.ca/en/vfrchartlist.pdf For general VFR dead reckoning airspace navigation: VNC - 1 : 500,000 This is a Lambert conformal conic projection. A line on this map is an arc of a great circle and will match your compass heading after you add variation (on the map as isogonal / agonic lines) and deviation (your airplanes specific compass' error card), though it will not stay the same if you want to follow the great circle. This is impossible to navigate without computerized navigation.  For busier areas (eg Toronto airspace): VTA - 1 : 250,000 This is a Transverse Mercator Projection .  A line on this map is a direct route to your destination, or a Rhumb line.  Rumb lines are easier to navigate because you use a constant bearing. A Rhumb line is a curved line that meets all meridians at the same angle. Is a straight line on a Transverse Mercator P...
