II. G - Navigation And Flight Planning

Question 1

True course? True heading? Magnetic course?

Answer 1

TC - The direction of flight as measured on chart clockwise from true North.
TH = TC +/- WCA
MC - true course corrected from magnetic variation

Question 2

ICE-T air speeds?

Answer 2

Indicated- speed shown on the airspeed indicator
Calibrated- IAS corrected for installation and instrument errors
Equivalent - CAS corrected for adiabatic compressible flow for the particular altitude
True - the speed at which an aircraft is moving relative to the surrounding air. Equal to CAS corrected for density altitude

Question 3

Terminal Area charts (TAC)?

Answer 3

Helpful when flying in or near class B Airspace (more detailed display)
Scale is 1:250000 (1” = 3.43 NM)
