IFR Written Flashcards
For a/c other than helicopters, what minimum weather conditions must be forecast for your ETA at an alternate airport that has a PRECISION approach procedure, with standard alternate minimums, in order to list it as an alternate for IFR flight?

91.169
What is the 3rd fundamental skill in instrument flying?
Aircraft control! (Pitch, bank, and power)
What indication does the BALL in the turn coordinator provide?

Prior to using GPS waypoints for RNAV, what can you do to check the current status of the GPS database?

NO! You must have either an unrestricted ATP-airplance cert or an airplane instrument rating
What is the primary pitch instrument when ESTABLISHING a constant altitude standard rate turn?
ALTIMETER
If during an ILS approach under IFR, the approach lights are not visible upon arrival at the DH, what do you do?
Immediately execute the missed approach procedure
What is the maximum tolerance allowed for an operational VOR equipment check when using a VOT?

What is the maximum tolerance allowed for an operational VOR equipment check when using an airborne checkpoint?
+/- 6 degrees
Military training routes above 1,500’ are depicted on:
IFR Low Altitude En Route Charts
Reception of signals from an off-airport radio facility may be inadequate to identify the fix at the designated MEA. In this case, which altitude is designated for the fix?
MRA (Minimum Reception Altitude) - the lowest altitude at which an intersection can be determined, assigned to fixes with an MEA
What are the 3 skills used in instrument flying (in order)
- Cross-Check
- Instrument Interpretation
- Aircraft Controls
When an alternate airport is required, what are the weather minimums that must be forecast at the ETA for an alternate airport that has a PRECISION approach procedure?
600ft ceiling and 2sm visibility at your ETA
91.169
If the pilot loses visual reference while circling to land from an instrument approach and ATC radar service is not available, the missed approach action should be to:
Follow the missed approach specified for that particular procedure - Make a climbing turn toward the landing runway and continue the turn until established on the missed approach course
If you are departing from an airport where you cannot obtain an altimeter setting, what should you set your altimeter to?
To the current airport elevation
The rate of turn at any airspeed is dependent upon:
The HORIZONTAL lift component!
Centrifugal force acts against:
The horizontal component of lift/the turn
When flying a GPS approach procedure, what effect will overriding an automatically selected sensitivity have?
It will cancel the approach mode annunciation
The pilot in command of a civil aircraft must have an instrument rating only when operating:
Under IFR, in weather conditions less than the minimum for VFR flight or in Class A airspace
Prior to conducting “timed approaches from a holding fix,” what is required?
The airport where the approach is to be conducted must have a control tower in operation
When the approach procedure involves a procedure turn, the maximum speed should be no greater than:
200 KIAS!
During a WAAS GPS approach, you receive an LNAV+V annunciation on the GPS display. What should you do?
Descend to LNAV approach minimums using the barometric altimeter to comply with altitude restrictions, referencing advisory vertical guidance as an aid - the altimeter remains the primary altitude reference - LNAV+V is advisory in nature and is not approved for vertical guidance!
To meet the minimum instrument experience requirements, within the last 6 calendar months you need:
- 6 Instrument Approaches
- Holding Procedures
- Intercepting and Tracking courses in the appropriate category of a/c
To ensure proper airspace protection while in a holding pattern, what is the maximum airspeed above 14,000’ for civil turbojet a/c?
265 knots!
What is the maximum speed for civil turbojet in holding patterns between 6,001’ to 14,000’
230 knots!
How can a pilot determine if a GPS installed in an a/c is approved for IFR en route and iFR approaches?
Flight Manual Supplement - a supplement to the a/c’s POH
What does the symbol T within a black triangle in the minimums section of the IAP for a particular airport indicate?
Takeoff minimums are not standard and/or departure procedures are published! - Consult the alternate takeoff procedure.
When operating under IFR with a VFR-on-Top clearance, what altitude should be maintained?
- A VFR cruising altitude appropriate to the magnetic course being flown and as restricted by ATC
When operating in VMC with an ATC authorization to maintain VFR-on-Top, what 3 things are pilots on IFR flight plans required to do?
- Fly are the appropriate VFR altitude
- Comply with the VFR visibility and cloud dist. criteria
- Comply with instrument flight rules that are applicable tot he flight (Min. IFR altitudes, position reports, clearnaces, etc.)
What cruising altitude is appropriate for VFR on Top on a westbound flight below 18,000’?
EVEN thousand-foot levels + 500, but never below MEA
During coordinated turns, what force moves the pendulous vanes of the vacuum-driven attitude indicator, resulting in precession of the gyro toward the inside of the turn?
Centrifugal
If the a/c’s transponder fails during flight within Class B airspace, what might ATC do?
Tell ATC!
ATC may authorize deviation from the transponder requirement to allow a/c to continue to the airport of ultimate destination.
One characteristic that a properly functioning gyro depends upon for operation is the:
Resistance to deflection of the spinning wheel or disc (RIGIDITY)
What is the IFR fuel requirement?
The amount of fuel required to fly to the destination airport, then to the alternate, plus 45 mins reserves!
The time entered in block 12 (fuel on board) of an IFR flight plan should be based on what fuel quantity?
Total usable fuel on board!
When using de-icing boots, the pilot should:
Activate the de-icing system at the first indication of icing and do so in accordance with the manufacturers guidance
A pilot has an IFR flight plan for July 10 of this year, what is the earliest date the pilot can meet the IFR experience requirements w/o having to take an IFR proficiency check?
January 10 of this year (within the preceding 6 calendar months)
For planning purposes, what is the highest usable altitude for an IFR flight on a VOR airway?
17,000’ (the VOR airway system consists of airways designated from 1,200’-17,999’)
If a DME becomes inop, what will the airborne DME do/indicate?
It will not transmit a coded identification audio tone…however a signal may still be received
What happens to residual ice that remains after de-ice boots are inflated and shed ice?
Residual ice increases with a decrease in airspeed or temperature
A particular VOR station is undergoing routine maintenance. This is evidenced by:
Removal of the identification feature (morse code tone) since navigation signals may still be transmitted
When using GPS for navigation and IAPs, any required alternate airport must have:
An approved operational instrument approach procedure other than GPS
How is a SKIDDING turn indicated on a turn coordinator?
The Ball will be rolled to the OUTSIDE of the turn (mini airplane banked in one direction, and ball is on the other side)
Using an average GS of 90 knots, what constant rate of descent from 3,100’ MSL at the 6 DME fix would enable the a/c to arrive at the FAF at 2,400’ MSL? (There are 3nm between 6 DME and the FAF)
- 700 feet to be lost in 3nm at 90 knots
- At 90 knots the a/c will cover 1.5nm per min, or 3nm in 2 mins
- 700’/2 = 350ft/min
