A
- Under instrument flight rules aka an IFR flight plan
- In weather conditions less than the minimum for VFR flight
- Class A airspace
- Under special VFR within B/C/D and E b/w sunrise and sunset
- when carrying pax for hire on cross-country in excess of 50nm miles or at night
3
Q
Outline the recency of experience requirements to be PIC of a flight in IFR
A
- Flight review within the past 2 years or a check ride.
- 3 takeoffs and landings within the preceding 90 days in an AC of the same category, class and type.
- Within the 6 calendar months preceding the month of the flight, performed and logged weather conditions or under simulated conditions have done: 6 instrument approaches, holding procedures and tasks, intercepting and tracking courses through the use of navigational electronic systems, 6 HITS
4
Q
Do you need an instructor to be present if you are planning on using an aviation training device to maintain your IFR currency?
A
No, as long as the category of AC for the instrument rating privileges to be maintained and the pilot performs the tasks and iterations in simulated instrument conditions. Needs to be logged.
5
Q
Do you need an instructor present when a using time in an FFS, FTD or ATD to acquire instrument experience for a pilot certificate or rating?
A
Yes, must be present.
6
Q
If a pilot allows currency to expire, what can you do to be current again?
A
You are current for the first 6 months following check ride or proficiency check. If you haven’t done the 6 hits, you cannot legally fly. To be legal, you have a grace period, of 6 months, to get current by finding a safety pilot and in simulated IFR to acquire the 6 approaches. If the second 6 month period passes, then you can get currency back 1) accomplishing proficiency check by examiner, an authorized instructor, or an FAA-approved person to conduct instrument practical tests.
7
Q
Explain current vs. proficient
A
Currency means the pilot has done the minimum FAA regulatory requirements within a specific time period to exercise privileges of the certificate. Proficiency means a pilot is capable of conducting a flight with a high degree of competence
8
Q
Safety pilot requirements
A
- Possess a private pilot certificate with category and class ratings for the AC flown
- Possess an appropriate medical certificate
- If the flight is in IFR flight plan, then the person acting as POC must hold an instrument rating and be current.
9
Q
Can a pilot who does not hold a medical certificate but has basic med authorization act as a safety pilot?
A
Only if the pilot acting as PIC while performing the duties of safety pilot. BasicMed cannot be exercised by safety pilots who are not acting as PIC yet are required members.
10
Q
Can an instrument rated pilot fly IFR under BasicMed?
A

35
When utilizing a GPS for IFR navigation, are you required to have an alternate means of navigation appropriate for the route of flight?
AC using non-WAAS must be equipped with alternate means of navigation like VOR. Active monitoring of that other equipment is not required if you have RAIM. WAAS devices don't need a secondary method.
36
Can a handheld GPS received be used?
VFR and handheld GPS systems are not authorized for IFR navigation, approaches or as a principal flight reference. May only be used as an aid to situational awareness.
37
During preflight, you notice several static discharge wicks are missing? Explain the function of them and the problems that could occur if they are missing.
Static wicks are installed to reduce radio receiver interference caused by corona discharge emitted from the AC as a result of precipitation static, which occurs during snow or rain. If it occurs, you could experience loss of VHF comms and erroneous magnetic compass readings.
38
When must a pilot file for IFR?
Prior to departure from within or prior to entering controlled airspace, a pilot must submit a complete flight plan and receive clearance from ATC if weather conditions are below VFR minimums.
39
When will ATC delete from the system a departure flight plan that has not been activated?
2 hours after the proposed departure time or expected departure clearance time.
40
When can a pilot cancel the IFR flight plan?
Operating in VFR conditions outside of class A airspace.
41
After filing an IFR flight plan, can you depart VFR and pick up clearance in the air?
A VFR departure can be used w/o having to wait for a slot in the IFR but you have to
1. maintain separation from other AC
2. maintain terrain and obstruction clearance. Can't fly in IMC w/o your clearance
3. departing VFR relieves ATC of duties, but you can only get safety alerts as workload permits
4. You must maintain VFR until you have obtained IFR clearance.

If not, alternate must be filed. If no minimums are specified then precision approach 600 feet and 2 statute miles and nonprecision 800 feet and 2 statute miles.
If no IAP has been published then, the ceiling and viz minimums are those allowing descent from MEA approach and landing under basic VFR.
45
What if the destination and alternates don't have TAF? How do you determine forecast?
Use GFA, graphical forecasts for aviation to determine ceilings and visibilities.
46
During preflight, you notice that your destination airport has no published IAP. The weather is 3000 and 5 miles viz 1hr before and after. Do you need to file an alternate?
Yes because it does not have a SIAP.
47
What is the definition of the term ceiling?
Ceiling is defined as the height above the Earth's surface of the lowest layer of clouds: broken. OVC
48
What minimums are to be used on arrival at the alternate?
If an IAP has been published for that airport the mins specified there.
49
What restrictions apply concerning filing an airport as an alternate when using non-WAAS equipment?
The alternate must have an instrument approach that does not require a GPS.
50
What instrument approach procedures may you flight plan to use as the planned approach at the required alternate when using WAAS.
Can use any instrument procedure.
51
You executed a MAP at your destination airport due to unforecasted weather and during climb you lose contact and make the decision to go to your alternate. Does ATC know the alternate? Can you divert to a different alternate than filed?
No, they don't know the alternate airport filed. If dviersion is necessary, pilots are expected to notify ATC and request an amended clearance. No requirement for you to prcoeed to your filed alternate, you can go to any alternate you deem appropriate. If loss of comms, then choose any airport you deem safe.
52
What restrictions apply to flight planning when using WAAS at the alternate?

67
How does an altimeter work?
Contains a stack of anaeroid pressure wafers set to stand pressure. Static air enters the casing from a port and they contract and expand based on the surrounding pressure. Compression of them is a higher surrounding pressure or a decrease in altitude.

Absolute: vertical distance above the terrain
Pressure altitude: the altitude read when the altimeter is set to 29.92 in HG.
Density altitude: pressure altitude corrected for variations in standard temperature
71
How does an airspeed indicator work?
The airspeed indicator is a scale that measures the difference between the static pressure from your static ports, and the ram pressure (dynamic + static) from the pitot tube. The static pressures cancel each other out resulting in a dynamic pressure measurement.
72
What are the airspeed indicator errors?
Static port ices over and you climb: airspeed is lower than what is indicated
Static port ices over and you descend: airspeed is faster than

Pitot and drain hole are blocked and you descend: airspeed is higher than indicated
73
Name the four different types of AC speeds
Indicated: what is shown on the ASI
Calibrated: indicated corrected for instrument error
Groundspeed: true airspeed corrected for wind
True: airspeed corrected for temperature and pressure

4200 MSL is the freezing level because of lapse rate 2C for every 1000 feet. 3000ft above ground is freezing level.
80
What corrective action to take if static port freezes or pitot tube freezes?
Alternate static source for static port and break VSI glass as a backup.
Pitot heat for the pitot tube.
81
If you need to use the alternate static source, how will the instruments be affected?
Altimeter - higher than actual
Airspeed - higher than actual
VSI - momentary climb then stable
82
