FAR Part 91 Quiz

#3

There are at least 2 ways to practice this quiz. One way is to check your answer by clicking the "Check answer" button. This will give you immediate feedback regarding specific questions. The other option is to simply answer all the questions as a test and "Flip the switch" or "Press the button" (grade the test) after the last question to receive a test score. You can then check each question individually to see which questions were missed. If you have any problems or suspect an error, feel free to contact me anytime.

Thank you and good luck.

1. A pilot is flying in IFR weather conditions and has two-way radio communications failure. What altitude should be used?

Last assigned altitude, altitude ATC has advised to expect, or the MEA, whichever is highest.
An altitude that is at least 1,000 feet above the highest obstacle along the route.
A VFR altitude that is above the MEA for each leg.

2. A pilot is holding at an initial approach fix after having experienced two-way radio communications failure. When should that pilot begin descent for the instrument approach?

At the EFC time, if this is within plus or minus 3 minutes of the flight plan ETA as amended by ATC.
At flight plan ETA as amended by ATC.
 At the EFC time as amended by ATC.

3. What altitude and route should be used if the pilot is flying in IFR weather conditions and has two-way radio communications failure?

Continue on the route specified in the clearance and fly the highest of the following: the last assigned altitude, altitude ATC has informed the pilot to expect, or to the MEA.
Descend to MEA and, if clear of clouds, proceed to the nearest appropriate airport. If not clear of clouds, maintain the highest of the MEA's along the clearance route.
 Fly the most direct route to the destination, maintaining the last assigned altitude or MEA, whichever is higher.

4. While in IFR conditions, a pilot experiences two-way radio communications failure. Which route should be flown in the absence of an ATC; assigned route or a route ATC has advised to expect in a further clearance?

The most direct route to the filed alternate airport.
An off-airway route to the point of departure.
The route filed in the flight plan.
5. What action is necessary when a partial loss of ILS receiver capability occurs while operating in controlled airspace under IFR?
Continue as cleared and file a written report to the Administrator if requested.
 If the aircraft is equipped with other radios suitable for executing an instrument approach, no further action is necessary.
 Report the malfunction immediately to ATC.
6. What action should be taken if one of the two VHF radios fail while IFR in controlled airspace?
Notify ATC immediately.
 Squawk 7600.
 Monitor the VOR receiver.
7. While flying IFR in controlled airspace, if one of the two VOR receivers fails, which course of action should the pilot in command follow?
No call is required if one of the two VOR receivers is operating properly.
 Advise ATC immediately.
 Notify the dispatcher via company frequency.
8. While flying in controlled airspace under IFR, the ADF fails. What action is required?
Descend below Class A airspace.
 Advise dispatch via company frequency.
 Notify ATC immediately.
9. When may a pilot descend below 100 feet above the touchdown zone elevation during a Category II ILS instrument approach when only the approach lights are visible?
After passing the visual descent point (VDP).
 When the RVR is 1,600 feet or more.
 When the red terminal bar of the approach light systems are in sight.

10. When is DME required for an instrument flight?

At or above 24,000 feet MSL if VOR navigational equipment is required.
In terminal radar service areas.
Above 12,500 feet MSL.

11. A function of the minimum equipment list is to indicate required items which

are required to be operative for overwater passenger air carrier flights.
may be inoperative for a one-time ferry flight of a large airplane to a maintenance base.
May be inoperative prior to beginning a flight in an aircraft.

12. In what altitude structure is a transponder required when operating in controlled airspace?

Above 12,500 feet MSL, excluding the airspace at and below 2,500 feet AGL.
Above 10,000 feet MSL, excluding the airspace at and below 2,500 feet AGL.
 Above 14,500 feet MSL, excluding the airspace at and below 2,500 feet AGL.

13. For what purpose may cockpit voice recorders and flight data recorders NOT be used?

Determining causes of accidents and occurrences under investigation by the NTSB.
Determining any certificate action, or civil penalty, arising out of an accident or occurrence.
 Identifying procedures that may have been conducive to any accident, or occurrence resulting in investigation under NTSB Part 830.

14. How long is cockpit voice recorder and flight recorder data kept, in the event of an accident or occurrence resulting in terminating the flight?

60 days.
 90 days.
30 days.
15. Information obtained from flight data and cockpit voice recorders shall be used only for determining
who was responsible for any accident or incident.
evidence for use in civil penalty or certificate action.
possible causes of accidents or incidents.

16. Which operational requirement must be observed by a commercial operator when ferrying a large, three engine, turbojet-powered airplane from one facility to another to repair an inoperative engine?

The computed takeoff distance to reach V1 must not exceed 70 percent of the effective runway length.
The existing and forecast weather for departure, en route, and approach must be VFR.
No passengers may be carried.

17. A commercial operator plans to ferry a large, four-engine, reciprocating-engine-powered airplane from one facility to another to repair an inoperative engine. Which is an operational requirement for the three-engine flight?

The gross weight at takeoff may not exceed 75 percent of the maximum certificated gross weight.
Weather conditions at the takeoff and destination airports must be VFR.
The computed takeoff distance to reach V1 must not exceed 70 percent of the effective runway length.

18. Which operational requirement must be observed when ferrying an air carrier airplane when one of its three turbine engines is inoperative?

The weather conditions at takeoff and destination must be VFR.
The flight cannot be conducted between official sunset and official sunrise.
Weather conditions must exceed the basic VFR minimums for the entire route, including takeoff and landing.

19. Which operational requirement must be observed when ferrying a large, turbine-engine-powered airplane when one of its engines is inoperative?

The weather conditions at takeoff and destination must be VFR.
Weather conditions must exceed the basic VFR minimums for the entire route, including takeoff and landing.
