Instrument Approach Types - QT
Lesson Quicktakes cover the items that should be memorized from each of the wifiCFI Lessons. They do not cover all of the lesson details in-depth.
PRECISION APPROACHES:
Azimuth Guidance.
Vertical Guidance.
Distance Information.
Approach Light System.
NON-PRECISION APPROACHES:
Azimuth Guidance.
May or may not include the other elements.
LOCALIZER SERVICE VOLUME:

LOCALIZER COURSE WIDTH:

GLIDESLOPE SERVICE VOLUME:

MARKER BEACONS:
Outer Marker (OM):
Light Color = Blue.
Beacon Code = - - - -
Location = Final Approach Fix (FAF).
Middle Marker (MM):
Light Color = Amber.
Beacon Code = - . - .
Location = 200’ AGL on Glidesope (DH).
Inner Marker (IM):
Light Color = White.
Beacon Code = . . . .
Location = CAT II Decision Height (DH).
LPV AND LNAV/VNAV APPROACHES:
Lateral and Vertical Guidance provided by GPS Satellites.
LOCALIZER BACK COURSE APPROACH:

LDA APPROACH:
LDA = Localizer Type Directional Aid.

SDF APPROACH:
SDF = Simplified Directional Facility.

OTHER NON-PRECISION APPROACHES:
VOR Approach:
Utilize VOR radials to guide pilot to runway.
RNAV Approach:
Utilize GPS satellites to guide pilot to runway.
PAR Approach (Precision Approach Radar):
ATC gives lateral and vertical guidance to pilot.
ASR (Airport Surveillance Radar):
ATC gives lateral guidance to pilot.
No-Gyro Approach:
ATC gives lateral guidance to pilot.
Requested by pilot if he/she has gyroscopic instrument failure(s).
Visual Approach:
Pilot lands under visual conditions.
Pilot must have airport or preceding aircraft in sight.
Can be assigned by ATC.
Contact Approach:
Pilot’s familiar with the area may follow known landmarks to approach and land at airport.
Must have at least 1 SM visibility.
Must be able to avoid clouds.
Is pilot requested (not ATC assigned).
