Which instrument is the primary bank instrument during a stabilized standard rate turn?

Answer: Turn coordinator

During a stabilized standard rate turn the turn coordinator is the primary bank instrument because it shows the rate being held.

What error causes the magnetic compass to indicate a turn toward the north when the aircraft accelerates on an east or west heading?

Answer: Acceleration error (ANDS)

Acceleration on east/west headings causes the compass to show a turn toward north, remembered by the mnemonic ANDS.

An instrument-rated pilot must have logged what recent experience to act as PIC under IFR within the preceding 6 calendar months?

Answer: Six instrument approaches, holding, and intercepting/tracking courses

The glideslope provides vertical guidance on an ILS, while the localizer provides lateral guidance.

A pilot loses two-way radio communication while operating IFR in IMC. What route should the pilot fly?

Answer: Assigned, then Vectored, then Expected, then Filed (AVEF)

Under lost communications in IMC, route is flown in order of Assigned, Vectored, Expected, then Filed (AVEF).

What is the standard service volume range of a low-altitude VOR below 18,000 feet?

Answer: 40 nautical miles

On an instrument approach, the term 'DA' refers to what?
