 Requires one reporting transmissometer – touchdown – controlling
1200 RVR (350 M) or 1000 RVR (300 M)

 Mid-field or rollout – one must be operational, but is advisory (except in Canada where midfield
must be reporting 600 RVR or better).
 1000 RVR (300 M) authorized only where 1000 RVR published on Approach Chart
 1000 RVR (300 M) only at certain foreign airports at this time
Cat II Approach
Considerations
 DH is identified by an RA as specified on the approach chart.
 For Cat II approaches (1200 or 1600 RVR), a coupled approach down to DH is required.
(AUTOLAND is recommended.)
 For Cat II approaches (1000 RVR), AUTOLAND is required.
 Arm Autoland or ILS as desired.
 Crew coordination procedures for CAT II are same as CAT III.
 AA Ops. Specs. authorize 100-foot HAT/1000 RVR. The number of transmissometers is tied
only to visibility.
CAT I Operations to RVR 18 Without TDZ and CL Lights
CAT I ILS operations to RVR 18 without TDZ/CL lights are authorized if the
operator employs the use of
 Flight Director (FD)
 Autopilot (AP) with an approach coupler
CAT I Operations to RVR 18 Without TDZ and CL Lights
Required Runway Lighting and Ancillary Equipment:
 A simplified Short Approach Lighting System with Runway Alignment Indicator Lights
(SSALR), Medium-Intensity Approach Lighting System with Runway Alignment Indicator
Lights (MALSR), or Approach Lighting with Sequenced Flashing Lights (ALSF-I, ALSF-II).
Some airports may have Ops Specs authority to use MIRL lighting.
 High Intensity Runway Lights (HIRL)
 A TDZ sensor of an RVR reporting system
 Runways must have—or be qualified for—a Standard Instrument Approach Procedure (SIAP)
with no restrictions to LOC course structure and alignment or glide path structure.
 Runways must have—or be qualified for—CAT I minimum of 200 feet DH and associated
visibility minimum of not more than RVR 24.

• May be flown to an RVR as low as 1000, 1200 or 1600, as published.
• RVR 1000 requires an AUTOLAND.
• RVR 1200 or 1600, a coupled approach down to DH is required
(AUTOLAND is recommended).
• Has a DH specified on the approach plate.
Cat III
• May be flown to an RVR as low as 600.
• Requires a DH of 50 feet.
• Requires AUTOLAND.

Autopilot requirement for Cat II approach
RVR 1200 or 1600, a coupled approach down to DH is required
(AUTOLAND is recommended).
1600 RVR (500 m)
Requires one reporting transmissometer:
– Touchdown: Controlling
1200 RVR (350 m) or 1000 RVR (300m)
Requires two reporting transmissometers:
– Touchdown: Controlling
– Mid-field or Roll-out: One must be operational but is advisory
(except in Canada where Mid-field must
be reporting 600 RVR or better)

One-dot deviation on PFD
.15 NM Approach
0.5 NM Terminal
1 NM En Route
The Waypoint (WPT) annunciator illuminates how long before sequencing the TO waypoint.
En Route 30 seconds
Terminal and Approach 10 seconds
When Autoland System Logic is Not Satisfied or Cockpit Setup Error Occurs,
 LND annunciator flashes – ARM Window.
 Check the following
 RUDDER TRAVEL UNRESTRICTED light illuminated
 ILS frequencies
 ILS course selectors
 Landing Flaps (28 or 40)
If flashing LND is not corrected, Autopilot disconnects at 300 feet and a Go-Around is
mandatory.
 Autopilot disengages.
 Autopilot warning annunciator illuminates.
 Aural warning sounds: “Autopilot.”
Non-ILS/Non-RNAV Approaches
 Vertical Deviation Indicator (VDI) is NOT available inside the FAF
 Flown using Vertical Speed mode, which results in constant rate approach.
Adding missing waypoints
may be added, except between FAF and MAP.
When is the PFD Lateral Course Deviation Indicator present
Indicator is always present unless an ILS frequency is tuned in the NAV receiver and
the NAV Display must be in the MAP mode.
Phase of Flight RNP
En Route (RNP 2 NM) ± 500 feet
Terminal (RNP 1 NM) ± 500 feet
Approach (RNP 0.3 NM) ± 150 feet
On final approach segment, a callout will be made anytime any crewmember observes an
UNABLE RNP or UNABLE APPROACH message or displacement greater than:
 2º on a VOR approach
 5º on an NDB approach
 1/3 dot (PFD) on a LOC approach
 1-dot (.015) lateral deviation on PFD for RNAV (GPS) Approaches
 Vertical deviation greater than half-scale on RNAV (GPS), VOR, or NDB Overlay
approaches
 When the underlying ground-based NAVAID indicates a course deviation described above
A stabilized approach with normal bracketing means the airplane must be:
• At Approach Speed (VREF + additives ± 5 knots).
• On the proper flight path at the proper sink rate.
• At stabilized (spooled up) thrust
