Which navigation instrument uses VHF signals to determine your bearing to a station?
ADF
DME
VOR
GPS
A VOR (Very High Frequency Omnidirectional Range) station transmits VHF signals that allow the receiver to determine the bearing to or from the station. ADF uses low- to medium-frequency NDB signals, DME measures distance, and GPS uses satellites.
Which instrument is not part of the six basic required for IFR flight?
Attitude Indicator
GPS
Altimeter
Airspeed Indicator
The six basic IFR instruments include the airspeed indicator, altimeter, attitude indicator, turn coordinator, heading indicator, and vertical speed indicator. GPS is not one of the required six traditional instruments.
In an ILS approach, what does the term "DA" stand for?
Decision Area
Decision Altitude
Descent Altitude
Descent Advisory
DA stands for Decision Altitude, which is the specified altitude in a precision approach at which the pilot must decide whether to continue the approach or execute a missed approach. It is expressed in feet above mean sea level.
Under IFR communication procedures, which transponder code indicates radio failure?
7600
7000
7700
7500
Squawking 7600 alerts ATC that you have experienced two-way radio failure. Code 7700 indicates an emergency, 7500 indicates unlawful interference, and 7000 is the standard VFR code.
If ATC clears you "direct" to a waypoint, what action should you take?
Fly over the next waypoint first
Fly directly to that waypoint along the shortest route
Circle the waypoint before proceeding
Maintain current heading
A clearance direct to a waypoint means you should proceed directly to that fix by the shortest available route. You do not need to fly any intermediate legs or maintain your current heading.
On a nonprecision approach, when can you descend below the minimum descent altitude (MDA)?
After reaching MDA with runway environment in sight and in a position to land
After flying the missed approach segment
Only after ATC gives permission
Immediately upon crossing the final approach fix
You may descend below the MDA only when you have the runway environment in sight and are in a position to safely land. Descending below MDA without visual reference risks terrain or obstacle collision.
How many degrees does a full-scale deflection represent on a conventional VOR course deviation indicator?
5°
10°
2°
15°
A full-scale deflection on a conventional VOR CDI represents 10° of course deviation. Each dot typically equals 2°, so five dots equals a 10° deflection.
For an IFR flight, what fuel reserve requirement must you plan for?
Fuel to destination only
Fuel to reach destination, then alternate, plus 30 minutes at cruise speed
Fuel to reach destination, then alternate, plus 45 minutes at cruise speed
Fuel to destination plus 45 minutes loiter at 500 ft AGL
Under IFR, you must plan for enough fuel to fly to your destination, then to your most distant alternate, and then have at least 45 minutes of reserve fuel at normal cruising speed.
If ATC assigns you an altitude that differs from your filed flight plan, what should you do?
Refuse the clearance
Immediately climb or descend to the assigned altitude
Remain at the filed altitude until approval
File a new flight plan
Under IFR, you must comply with ATC-assigned altitudes even if they differ from your flight plan. If unable, you must request an amended clearance, but you should not ignore the ATC instruction.
Which holding pattern entry should you use if your inbound course crosses the holding course by 80°?
Teardrop
Parallel
No entry
Direct
With an 80° intercept angle between inbound and your heading, the parallel entry is appropriate. Direct is used for intercept angles under 70°, and teardrop for angles between 110° and 180°.
What is the maximum allowable error for a VOR receiver check when using a VOT test?
±10°
±6°
±2°
±4°
The allowable tolerance for a VOR receiver when performing a ground VOT check is ±4°. Any deviation beyond that indicates the receiver is out of tolerance.
When not being radar vectored, when are you required to report your position under IFR?
Only if requested by ATC
When passing Flight Level 180
Every 10 minutes
At compulsory reporting points
Without radar vectors, IFR pilots must report over compulsory reporting points, as indicated on enroute charts. This ensures ATC maintains traffic separation.
After a vacuum pump failure, which primary instrument will likely become unreliable?
Altimeter
Magnetic compass
Airspeed indicator
Attitude indicator
A vacuum pump drives the attitude gyro (and sometimes the heading gyro). If the pump fails, the attitude indicator will malfunction, while pitot-static instruments and the magnetic compass remain functional.
What phraseology indicates you must await ATC clearance before departure from an IFR clearance limit?
Release pending
Hold for release
Standby for clearance
Cleared as filed
The term "Hold for release" means you cannot depart until ATC explicitly clears you to do so. It is a standard IFR clearance phraseology.
Which enroute minimum altitude ensures both obstacle clearance and adequate navigation signal coverage?
Minimum Obstruction Clearance Altitude (MOCA)
Minimum Enroute Altitude (MEA)
Minimum Crossing Altitude (MCA)
Maximum Authorized Altitude (MAA)
The MEA ensures that you have sufficient obstacle clearance and reliable navigation signal reception along the route segment. MOCA only guarantees signal reception within 22 NM of the navaid.
For an RNAV (GPS) LPV approach, which minima category relies on barometric VNAV?
LPV
LNAV/VNAV
LP
LNAV
LNAV/VNAV minima use barometric vertical navigation (baro-VNAV) to provide vertical guidance. LPV uses WAAS vertical guidance, while LNAV and LP provide lateral guidance only.
During a precision approach, you observe an unstable descent below 500 ft AGL. What is the safest action?
Execute a go-around
Level off until stabilized
Continue and adjust on final
Reduce power and flare early
An unstable approach below 500 ft AGL increases the risk of runway excursions or hard landings. Executing a go-around is the recommended safe decision.
On a low altitude IFR chart, what distinguishes the MOCA from the MEA?
MEA assures obstacle clearance but not nav signal
MOCA assures obstacle clearance and nav signal coverage everywhere
MEA assures nav signal and clearance; MOCA assures clearance within 22 NM of facility
There is no difference
MEA guarantees both obstacle clearance and navigation signal coverage along the entire route segment. MOCA guarantees obstacle clearance but only ensures VOR reception within 22 NM of the station.
According to the mnemonic ANDS, what happens to the magnetic compass when accelerating on an east heading?
It shows no change
It dips toward north
It swings south
It swings west
ANDS stands for "Accelerate North, Decelerate South." When accelerating on an east or west heading, the compass indication will falsely swing toward north.
In a two-way radio failure under IFR, which altitude should you fly?
Minimum IFR altitude only
Expected altitude only
Last assigned, the minimum IFR altitude, or the expected altitude, whichever is highest
Last assigned altitude only
After a two-way radio failure, you must fly the highest of the last assigned altitude, the minimum IFR altitude for the route segment, or the altitude ATC has advised to expect.
