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).
