V-tail

[Ref Pilot’s Handbook of Aeronautical Knowledge, FAA-H-8083-25B Page 6-8] What’s V-tail design? two slanted tail surfaces (fixed surface) + ruddervators (movable surfaces) V-tail design utilizes two slanted tail surfaces to perform the same functions as the surfaces of a conventional elevator and rudder configuration.

Magnetic? or True?; AGL? MSL?

As you may know that the true north is different from magnetic north – true direction ≠ magnetic direction. Then when we look at the charts and weather report/forecast, or when we hear the information form the ATC controller, whether these information is based on true or magnetic direction? Similar question is that when we […]
