IFR specifics from the AIM Flashcards
What is the VOR frequency Band?
108.0-117.95 MHz (1-1-3(a.))
How do you use a VOT test Frequency?
Tune the VOT test frequency located in the Chart Supplement. Center the CDI, it should read 0 degrees from or 180 degrees to (1-1-4(b.))
What is the typical VOT frequency?
108.0 (1-1-4(e.1))
To what distance can you reliably receive DME information and to what level of accuracy?
199 NM and to 1/2 nm or 3 percent of the total distance, whichever is further. (1-1-7(b.))
Where can you find NAVAID service volume restrictions?
Notams and then under the listings of NAVAIDs in the Chart Supplement (1-1-8(b.))
What are the Maximum ranges for each type of VOR?
70 NM for VL and 130 for VH VORs (Fig 1-1-3)(P. 475)
What are the components of an ILS?
Guidance info: Localizer, GS
Range info: Beacon
Visual Info: Approach lights, runway lights, touchdown and centerline lights
(1-1-9(a.3.))
How far off course must you be for a full-scale Localizer deflection while at the runway threshold?
350 ft to either direction of the centerline (1-1-9(b.2.))
What is the maximum differential between an LDA’s approach course and the runway in order for the approach to have straight in minimums?
30 Degrees (1-1-9(c.2.))
What is the typical glide slope angle on an ILS?
3 Degrees (1-1-9(d.3.))
What is the minimum DH for a CAT 1 ILS?
200 FT (1-1-9(i.1.a))
What is RAIM? How does it work and what are the requirements for a RAIM check?
Receiver Autonomous Integrity Monitoring (RAIM) determines if the satellites being used are meeting the performance requirements for a specific phase of flight, it requires 5 satellites to be in view of the receiver. A RAIM check can be completed using 4 satellites + baro-aiding (1-1-17(3.))
What is FDE? How does it work and what are the requirements for it?
Fault Detection and Exclusion (FDE) is the ability of the GPS to determine if a failed satellite is being used by the GPS. If the FDE detects a failed satellite it will exclude its information when determining positional information. It required 6 satellites for 5 + Baro aiding (1-1-17(3.a))
What TSO standard does your GPS fall under and is it IFR legal?
Our GTN 650 falls in accordance with TSO-146c, making it IFR compliant, it is also a WAAS GPS, so we don’t have to conduct a RAIM check during preflight (1-7-17(2.a.1))(Garmin - GTNxi Series Pilot’s Guide)
If your IFR GPS database doesn’t have a waypoint that you intend to use, can you just manually insert the point with longitude and latitude?
No, you may attempt to update the database but you must be able to retrieve waypoints to be used under iFR by name (1-1-17(2.b.3))
