What is the semi circle rule?
Semicircular rule Your aircraft has track between 180° and 359°, your flight level or altitude must be even. By following the semi-circular rule, an IFR aircraft will limit possible conflicts with another aircraft coming from the opposite direction through providing 1000ft separation between opposite west/east tracks.

How high can a VFR pilot fly?
VFR cruising altitude rules in the US and Canada In the US, there are specific VFR cruising altitudes, based on the aircraft’s course, to assist pilots in separating their aircraft while operating under visual flight above 3,000 ft above the surface (AGL) but below 18,000 ft Mean Sea Level (MSL).
Can you fly VFR at 3000 feet?
There are a few things worth emphasizing about this rule. First, you only need to comply with the VFR cruising altitudes if you are flying more than 3,000 feet above ground level (agl). Below 3,000 feet agl, you are not required to follow the altitude rule (although it’s a good idea) and neither are other aircraft.
What are basic VFR minimums?
Basic VFR Weather Minimums cloud ceiling at least 1,000 feet AGL; and. ground visibility at least 3 statute miles (usually measured by ATC but, if not available, flight visibility at least 3 statute miles as estimated by the pilot).
