CFI questions
Action of the elevators moves the plane on its... lateral axis
When did the Private Pilot ACS take effect for testing standards? June 2018
What FAR refers to Day VFR equipment required for flight? 91.205
91.213 refers to what? Inop instruments and equipment Affective domain relates to attitudes, beliefs, and values
According to the ACS, the student must bring a flight plan to the checkride. How far must the flight plan be planned to? First fuel stop
In a guided discussion, learning is achieved through the skillful use of questions
What is FDE? Does it effect what airports we can choose as alternates? Do all of our planes have it?
FDE is an ability provided through the GPS system receivers on the aircraft. 3 satellites provide 2D, 4: 3D, 5: RAIM (receive autonomous integrity monitoring) and we receive fault detection, 6: is fault detection and exclusion. It can affect the airports we choose especially if we are flying IMC and have to execute a missed approach due to losing RAIM and FDE. This inhibits our selections of airports a little.
I am not sure if all of the planes at USU have it. But it would seem logical that they do because we are supposed to compute RAIM for IFR flights.
How can you tell if your plane is equipped with WAAS?
Navigate to the AUX Chapter and then to the GPS Status page. If there is an SBAS softkey on the bottom of the MFD, your G1000 is equipped with WAAS/SBAS.
List what you would need to see in order to operate below the
DA/MDA. Additionally, list the FAR that tells us this.
FAR 91.175
(i) The approach light system, except that the pilot may not descend below 100 feet above the touchdown zone elevation using the approach lights as a reference unless the red terminating bars or the red side row bars are also distinctly visible and identifiable.
(ii) The threshold.
CFI questions
(iii) The threshold markings.
(iv) The threshold lights.
(v) The runway end identifier lights.
(vi) The visual glideslope indicator.
(vii) The touchdown zone or touchdown zone markings.
(viii) The touchdown zone lights.
(ix) The runway or runway markings.
(x) The runway lights.
What is a VDP? a defined point on a straight-in, non-precision approach from which you can descend below the MDA, as long as you have the required visual references
How could you calculate your VDP if one isn’t provided?
Take the AGL value of the MDA and divide it by 300.
Where is the missed approach point for the localizer 17 into Logan? Runway Threshold
What are the three different lapse rates? Environmental lapse rate (standard lapse rate) 3 degrees F per 1000 ft
Dry adiabatic lapse rate: 5.5 degrees F per 1000 ft
Saturated (wet) adiabatic lapse rate 1.5 degrees F per 1000 ft
APPROXIMATELY
What do the following takeoff minimums mean? How do you know if you can meet that climb gradient? Given the following
winds, temperature, and altimeter setting could you legally depart?
Rwy 17, 400-2 or standard with minimum climb of 270’ per NM to 4900
CFI questions
02017G22KT 10SM OVC014 09/06 A3014 RMK AO2 RAB34E46 SLP204 P0000 T00940061
Runway 17 400 fpnm climb gradient with 2 sm visibility. or standard visibility with min climb of 270' per nm to 4,900 ft. wind from 020 17 knots gusting 22 knots. 10 sm visibility overcast 14000 temperature (C) 09 dewpoint 06 Altimeter setting 30.14 rain began 34 min after the hr ended 46 min after the hour. You would have to calculate your climb gradient based on your weight, the aircraft and density / pressure altitude.
According to policies at USU you could not depart, but the FAA does not have any regulations stopping you. Based on experience with a temperature like that you could probably make that climb gradient.
Up to what percentage of the Instrument can be done in the simulator? Part 141 rules stipulate you cannot exceed 50% of total training time for this course within the SIM.

CFI questions
No: known icing conditions, I would not recommend doing so unless you have an aircraft equipped for it and even then I would consider not going.
Describe the different methods for inspecting the VOR in the airplane.
VOT: tune it to testing facility set to 0 degrees CDI centered should read 0 To the VOT. Tune to 180, CDI centered should read From the VOT.
VOR checkpoint: Tune to radial +/- 4 degrees from specified radial
Dual VOR: tune both Nav radios to the VOR with TO indications. Note the bearings should be within +/- 4 degrees.
Airborne: Select a radial on an established airway, select a prominent point approx 20 nm for the VOR. tune to VOR with a TO indication should read +/- 6 degrees.
How does the attitude indicator and Airspeed Indicator work on the G1000? Attitude indicator: operates on the gyroscopic principle of rigidity in space. Detects pitch and bank through the AHRS system and the ADC. This data is gathered from LRU's and communicates the information it gathers to the ADC. Solid state gyros, magnetometers, and accelerometers help determine the type of information that is gathered.
ASI: The pitot probe and static air are measured within the ADC and the LRU's.
This data is displayed on the PFD within the G1000.
What is a contact approach and a cruise clearance? Contact approach: Flown the same way as a visual approach, but you don't need the airport in sight. You need to remain clear of clouds, have 1 statute mile of flight visibility, and reasonably expect to continue to the airport in those conditions. Plus, the airport must have a published instrument approach. There's no missed approach procedure.
Cruise clearance:
issued to allow a pilot to conduct flight at any altitude from the minimum IFR altitude up to and including the altitude specified in the clearance. Also authorizes a pilot to proceed to and make an approach at the destination airport. Climbing/descents within the block is to be made at the discretion of the pilot. However, once the pilot starts descent and verbally reports leaving an altitude in the block, the pilot may not return to that altitude without additional
ATC clearance.
What is the MON network?
A list of airports that have ILS and VOR approaches designated as backups if the GPS system is disrupted. FAA plans to decommission 30% of existing VOR network and only keep a few for navaids.
CFI questions
What are the elements of an IFR clearance? C: Clearance limit
R: Route
A: altitude
F: frequency
T: Transponder code
What is Vtgt? It is the target speed you will be using for your approach.
On the Idaho Falls Departure procedure what does CW mean? Clockwise
Describe how to correct for wind in a hold Calculate your wind correction angle on the inbound leg and triple that on your outbound leg. What is the lowest altitude you can have the autopilot engaged while on an instrument approach Regulations: 500 ft AGL 14 CFR 135.93.
AFM: The autopilot must be disengaged below 200 feet AGL during approach operations and below 800 feet AGL for all other phases of flight.
How can you calculate the bank degrees needed for a standard rate turn partial panel? Standard rate turns of 3 degrees per second will require different angles of bank depending on true airspeed (faster=more bank, slower=less bank) Rule of thumb: 15% of true airspeed is about the bank angle necessary to achieve a standard rate turn.
Doing this partial panel requires you to know your speed by utilizing the PFD backup display button. Because this will display your TAS of the MFD (assuming the PFD has failed) if it hasnt and the MFD has you already have that information.
You can also add 2% to your Indicated Airspeed (IAS) for every 1,000 feet of altitude to approximate the TAS.
CFI questions
Describe how you would execute a missed approach from a circle to land Make the initial climbing turn toward the landing runway and then maneuver to intercept and fly the missed approach course.
What are the 141 requirements to obtain an instrument rating, and what are the specific cross country requirements. No specific cross country other than a flight at least 250 nm along airways or ATC directed routes. With one leg at least 100 nm straight line. IAP at each airport and three different kinds of approaches.
35 hours of instrument training
Knowledge areas FAR 61.56
What is p-static? What purpose do static wicks have? P static refers to the noise and interference that could result from a buildup of static electricity. As the aircraft moves through the air it creates friction, this friction induces static electricity. When this builds up enough it could interfere with navigational and radio signals. The static wicks enable the energy generated from moving to be transferred back into the atmosphere without interfering with aircraft operations.
How many static wicks are required to be on the DA-40 for IFR flight? According to 91.205 they are not required. Reading through the AFM I have not
seen this detailed either, so unless there is a policy USU has instituted I would say they are not required. But they are a good idea, there are 4 of them on the DA-40.
What is the difference between LNAV, LNAV/VNAV, LP, and LPV on RNAV approaches LNAV: WAAS capable systems enable this approach to be flown with vertical guidance advisory. you need to use LNAV minimums but you have a glideslope helping you maintain a steady descent 9advisory).
LNAV/VNAV: approaches with vertical guidance used in tandem with baro aided GPS units. Mainly used with WAAS today, they do not funnel you to the runway but have a .3 nm limit within 2 miles of the final approach fix to the missed approach point. 250 ft above TDZ
LP: non precision approach with WAAS as lateral guidance, no vertical. Typically in areas that do not allow vertical guidance to be published.
LPV: is a WAAS/GPS approach similar to an ILS they are considered an APV. The LPV approach scales down as you get closer to the runway funneling you to the the threshold. Does not meet FAA/ICAO guidelines for precision approach. 200 ft above TDZ

Your mission was extended 90 minutes requiring at least one additional aerial refuel. The moon has now set. A shift in prevailing winds causes an infrequently used runway to be active. You are less familiar with the approach to this runway and have only used it during VFR conditions. The instrument approach plate reveals you will fly a prolonged DME arc taking you out over the unlit desert away from the dimly lit base. While flying the above instrument approach, you take another look at the approach plate. When you look up again the airfield lights are visible through the upper portion of your canopy. You did not sense any change in your aircraft attitude. Which of the following best describes what happened while you looked at the approach plate? OA. The black hole effect has amplified the normal reflection of the airfield lights…arrow_forwardPlease give a complete solution in Handwritten format. Strictly don't use chatgpt,I need correct answer.
