Instrument Checkride GK (Approach Plates, IFR Sup, FIH)
Terms in this set (18)
Approach selected must be compatible with navigation equipment installed and operating on aircraft [217v1 - 18.104.22.168]
* Including missed approach instructions (though alternate MAP may be requested prior to accepting clx]
2) You can only fly an approach for your category aircraft or higher
3) A current copy of the IAP must be available. Consult the TCN to make sure the approach is current.
4) Pilots shall not begin an en route descent, arrival, or published approach if destination's wx below req'd mins(vis only for straight-in or sidestep approaches) [202v3 - 8.17]
DA/DH vs. MDA
-MDA - Lowest altitude (normally MSL) to which descent authorized on final approach or during circling [217v3-p202]
* Where no electronic glideslope is provide
-DA/DH - Specified altitude on a precision approach where decision must be made to continue or execute missed approach
* Outside the NAS, decision altitude (DA) is referenced to MSL and decision height (DH) references threshold elevation
HAT v. HAA
- HAT - Difference between MDA or DA/DH above the highest runway elevation in the touchdown zone. [217v3-p201]
* Touchdown zone is the first 3,000 feet of the runway.
* HAT is published on instrument approach charts in conjunction with all straight-in minimums
- HAA - Height above aerodrome, noting the height of the MDA above the published airfield elevation. (circling approach)
TDZE v. Elevation
- TDZE - Touchdown Zone Elevation is the highest point in the first 3,000 feet of landing surface [217v1-22.214.171.124.2]
- Elevation - the MSL altitude of the highest point of an airport's useable runways
- For USAF aircraft, straight-ins can be flown using vis requirements only; circling approaches require both ceiling and vis.
- The minimum visibility and cloud ceiling required to commence a given IAP
- CHECK ABOUT CONTINUING WITH CLOUD IN THE WAY
Once the aircraft is inside the FAF, one navigation receiver must remain tuned to and display the facility that provides final approach course guidance.
-Due to having only one VOR receiver, we can only cross tune intersections up to the final approach fix in the T6.
Missed approach instructions
- Shown in text at top and graphically in profile view
-Clearance for the approach is clearance for the published missed approach as well [217v1 - 14.3]
- Multiple approaches require departure/ climbout instructions prior to the FAF [217v1 - 14.3.1]
- When practices instrument approaches under VFR, aircraft is not automatically cleared for the published missed [126.96.36.199]
- Pilot should tell ATC how approach will terminate prior to beginning the approach
Minimum Safe Altitude v. Emergency Safe Altitude
- MSA - Min altitude providing at least 1k feet of obstacle clearance for emergency use w/in a specified distance to NAVAID
* Minimum sector is 1k feet of clearance w/in 25 NM of facility and is used if more than 1 min safe alt is required.
* Minimum safe altitudes do not guarantee NAVAID reception.
- ESA - Provides 1k feet of obstacle clearance (2k mountainous areas) w/in 100 NM of facility (normally only military procs).
- Important information of short term nature that may impact preflight planning.
* Temporary in nature or not known sufficiently in advance to permit publication in FLIP.
* Includes aiport/ runway closures, NAVAID issues, radar availability, obstacle or airfield lighting.
Types of NOTAMS
* Airfield Notams
* ARTCC Notams - Air Route Traffic Control Center
* Civilian (FAA)
1) D (distant) Notams - requiring wide dissemination, obtain from any FSS, about airfields NAVAIDS
2) FDC (flight data center) Notams - request specifically: Change in standard instrument arrival (SIA), flight restrictions, aero chart revisions, etc within 400 NM Area beyond servicing FSS
* NTAP - Notams expected to remain in effect for an extended period of time (greater than 90 days), Expected to reference NTAP first before contacting FSS
* A/FD Notams - Notams of a permanent nature are contained in the A/FD, obtain at base ops: for civil airfields not in IFR Sup
* L- Local - About airfields (call particular airfield/servicing FSS)
Basic Airfield Lighting
* White lights on either side, green threshold lights, red departure end lights.
Pilot controllable lighting (distinguished by the L or lighting system displayed in the negative)
* HIRL-High Intensity Runway Lighting, Military sometimes yellow up to runway last 2000'
* MIRL- Medium Intensity Runway Lighting
* LIRL- Low Intensity Runway Lighting
* Runway End Identifier Lights
(REIL)- Approach end, Flashing White (more easily vis at night/bad vis), May have 2 step/may be pilot activated (3, 5 sec), 1 step off with 5 clicks, 5 sec
* Activated by keying the radio on the depicted freq either 3, 5, or 7 times within a 5 second period (on for 15 minutes).
Multi Step Lighting (intensity can be varied by ATC or pilot)
* Check A/FD in IFR Sup for multi step info per field
* 3 step HIRL: HIRL, MIRL, LIRL (7,5,3 clicks, 5 sec)
* 2 step HIRL: HIRL, LIRL (7,3 clicks, 5 sec)
* Black Oval, White L (airport sketch) pilot controlled
* Airports without a control tower or intermittently manned tower.
* Remain on for 15 minutes (can't be turned off)
* Refer FIH for more info
"TDZ/CL RWY ##'
* Rows of white available in runway first 3000'
* White from threshold
* White/Red 3000' to 1000' runway remaining
* Red last 1000'
Approach Lighting System
* Supplements electronic NAVAIDs
* Green row is approach end
* Rows of white define extended centerline
* Row width, # of rows, row spacing differ between system
* Refer to FIH ALS legend
* ALS symbol - circled "A"
* Subscript is type of ALS
* Black dot (top of circle) indicates sequenced flashing
* Negative symbology (white on black) is pilot controlled/activated
* NOTAMS are published if ALS is inop due to change in required wx minimums
1) Squawk 7600
2) Monitor Guard
* VMC - mx VMC and continue under VFR, land as soon as practicable and notify ATC
* IMC - Continue according to FIH and remember AVE FAME
Route - AVE F = order of route precedence
1) Assigned Rout
2) Vectored Route
3) Expected Route
4) Filed Route
Altitude - AME = highest of the three options
1) Assigned altitude
2) Minimum altitude for IFR (MEA)
3) Expected altitude
