True course is 090°, TAS is 120 knots, and the wind is from 180° at 20 knots. What true heading should the pilot fly?
Answer: Approximately 100°
A 20-knot direct crosswind from the right at 120 knots TAS requires about a 10° right wind correction, so the heading is about 100°.
True course is 270° and magnetic variation is 10°E. What is the magnetic course?
Answer: 260°
East variation is subtracted from true course ("east is least"), so 270° − 10° = 260°.
Which correction converts magnetic heading to compass heading?
Answer: Deviation
Deviation is the aircraft's own compass error, listed on the compass correction card, and it converts magnetic heading to compass heading.
Under 14 CFR 91.151, what is the minimum fuel reserve for a VFR flight in an airplane during the day?
Answer: 30 minutes at normal cruise
Day VFR in an airplane requires enough fuel to reach the first point of intended landing plus 30 minutes at normal cruising speed.
What does an isogonic line on an aeronautical chart connect?
Answer: Points of equal magnetic variation
Isogonic lines join points with the same magnetic variation, and the agonic line marks zero variation.
How many nautical miles are in one degree of latitude?
Answer: 60 NM
Each degree of latitude spans 60 nautical miles, so each minute equals 1 NM.
What is the scale of a VFR Sectional Aeronautical Chart?
Answer: 1:500,000
Sectional charts use a 1:500,000 scale, which is about 6.86 NM per inch.
