Which VFR cruising altitude is appropriate on a magnetic course of 225° when more than 3,000 feet AGL?
Answer: 6,500 feet MSL
On magnetic courses from 180° to 359°, VFR pilots fly even thousands plus 500 feet, such as 6,500 feet.
On a standard VOR indicator, a full-scale CDI deflection represents how many degrees off the selected course?
Answer: 10°
A full-scale VOR CDI deflection is 10°, with each of the five dots worth about 2°.
What is the maximum permissible bearing error when checking a VOR receiver with a VOT?
Answer: ±4°
Under 14 CFR 91.171, a VOT check must read within ±4° of the 360° FROM or 180° TO indication.
For IFR operations, within what period must the VOR equipment have been operationally checked?
Answer: The preceding 30 days
14 CFR 91.171 requires a VOR check within the preceding 30 days before using the VOR under IFR.
The OBS is set to 360° with a TO indication and the CDI needle is deflected to the right. Where is the aircraft relative to the station?
Answer: Southwest of the station
A TO indication with 360° selected places the aircraft south of the station, and a right needle means the course lies to the east, so the aircraft is southwest.
At a groundspeed of 90 knots, how long does it take to fly 45 NM?
Answer: 30 minutes
At 90 knots, 45 NM takes 45 ÷ 90 = 0.5 hours, or 30 minutes.
An airplane burns 8 gallons per hour. How much fuel is needed for a flight of 2 hours 15 minutes, not counting reserves?
Answer: 18 gallons
8 gph × 2.25 hours = 18 gallons.
