If a VFR flight plan is not closed or extended, how soon after the ETA does Flight Service normally begin search procedures?
Answer: 30 minutes
Search and rescue procedures normally begin if the VFR flight plan is not closed within 30 minutes after the ETA.
When is DME slant-range error greatest?
Answer: At high altitude close to the station
DME measures slant range, so the error is largest when the aircraft is high and close to or over the station.
Magnetic heading is 030° and the ADF shows a relative bearing of 090°. What is the magnetic bearing TO the station?
Answer: 120°
Magnetic heading plus relative bearing equals magnetic bearing to the station: 030° + 090° = 120°.
What navigation method relies mainly on visual reference to landmarks?
Answer: Pilotage
Pilotage is navigation by visual reference to landmarks shown on a chart.
Which navigation method computes heading and groundspeed from known TAS, wind, time, and distance?
Answer: Dead reckoning
Dead reckoning uses computed values (TAS, wind, heading, time) to estimate position without outside references.
After flying 60 NM, a pilot is 4 NM off course with 60 NM still to go. Using the 1-in-60 rule, what total heading change will take the airplane directly to the destination?
Answer: 8°
You need 4° to parallel the course plus 4° to converge over the remaining 60 NM, for 8° in total.
Using the rule of thumb that TAS rises about 2% per 1,000 feet over IAS, what is the approximate TAS at 10,000 feet with an IAS of 120 knots?
Answer: 144 knots
2% × 10 = 20%, and 120 × 1.2 ≈ 144 knots TAS.
