Chapter 2 ALL WEATHER TERMINAL AREA OPERATIONS
Section 3 Approval of Small Category A Aircraft for Category
II Operations—Part 91
4-210 OVERVIEW. The general process of approval or acceptance
of certain operations, programs, documents, procedures, methods, or systems
is an orderly method used by Flight Standards Service (AFS) inspectors to
ensure that such items meet regulatory standards and provide for safe operating
practices. It is a modular, generic process that is ideally suited for the
approval of Category (CAT) II programs that are solicited by operators from
the Federal Aviation Administration (FAA). It is important for an inspector
to understand that the process described in this section is not all inclusive,
but it is rather a tool to be used with good judgment in conducting day-to-day
duties and responsibilities.
4-211 APPLICABILITY. The purpose of this section is to provide
operational system safety oversight, analysis, and guidance to principal
inspectors (PI) and All Weather Operations Specialists (AWOS) on the authorization
of operators of small Category A aircraft (including airplanes and rotorcraft)
to conduct CAT II instrument landing system (ILS) and/or Copter ILS with
a decision height (DH) below 200 feet approach and landing operations. The
principal operations inspector (POI) authorizes these operations via the
issuance of letter of authorization (LOA) C059, with concurrence of the
regional Flight Standards division (RFSD). The Next Generation (NextGen)
Branch (AXX-220) is the point of contact (POC) for CAT II operator approval.
The process in this section applies only to U.S. operators of small Category
A aircraft under Title 14 of the Code of Federal Regulations (14 CFR)
part 91. See Volume 4, Chapter 2, Section 2 for the process
to authorize operators for CAT II/III operations under 14 CFR
part 91 subpart F (part 91F)(large aircraft), 91 subpart K (part
135, and to authorize other helicopter operators for
Copter ILS operations with a DH less than 200 feet.
4-212 PROGRAM TRACKING AND REPORTING SUBSYSTEM (PTRS) ACTIVITY CODES.
POIs shall make a PTRS entry to record the actions directed by this
section. The PTRS entry shall be listed according to the applicable phase
as annotated below. POIs should use the “Comments” section to record comments
about interaction with the operators. The applicable PTRS codes for this
task are as follows:
· CAT II and/or Copter ILS with DH below 200 feet approval for
a small Category A aircraft operator: 1430.
· Copter ILS: 1220. Copter ILS approach procedures to minimums
lower than 200 feet DH. The PTRS code is “1220” and the “National Use” field
entry should be listed as “HBAT CILS.” The comments section of the PTRS
should be used to record the disposition of the applicant’s request.
4-213 PREREQUISITES AND COORDINATION REQUIREMENTS.
A. Prerequisites. This task requires knowledge of regulatory
requirements of part
91 and FAA policies and qualification as an aviation safety inspector
B. Coordination. This task requires coordination with avionics
and airworthiness units.

A. Category (CAT) A Aircraft. A grouping of aircraft based
on a speed of 1.3 times the stall speed in the landing configuration at
the maximum certificated landing weight, and that speed must be less than
91 knots. The FAA authorizes deviation for an operator of a small Category
A aircraft (less than 12,500 pounds certificated takeoff weight) to use
such an aircraft in CAT II operations without meeting the requirements of
B. Copter Instrument Landing System (ILS) Approach Approval.
An authorization issued after a successful demonstration of this capability
provides the holder the authority to descend to a DH of less than 200 feet
with a visibility as low as Runway Visual Range (RVR) 1200, while conducting a Copter ILS approach or a CAT II ILS
procedure. Operations of this type are currently considered only in the
case of Copter ILS approaches as described in paragraph 4-218.
C. Standard Category (CAT) II Operations. CAT II operations
are approach and landing operations conducted with a DH of less than 200
feet (60 meters), but not less than 100 feet (30 meters), and an RVR of
not less than 1,200 feet (350 meters).
4-216 OBJECTIVE. The objective of this task is to determine
if an operator of a small Category A civil aircraft (airplane or rotorcraft)
has developed acceptable procedures to conduct safe instrument approaches
to CAT II minimums and/or Copter ILS minimums with a DH below 200 feet.
Successful completion of this task results in acceptance or rejection of
the operator’s proposed CAT II procedures manual (if required) and issuance
or denial of LOA C059 to part
91 small Category A aircraft operators.
4-217 APPROVAL METHOD. A part
91 small Category A aircraft operator is issued LOA C059 in Web-based
automated Operations Safety System (WebOPSS) for CAT II operations and/or
Copter ILS operations with a DH below 200 feet.
4-218 SMALL Category A AIRCRAFT CAT II AND COPTER ILS OPERATIONS.
The DH and RVR for an aircraft on an ILS approach is specified on the part
97 Standard Instrument Approach Procedure (SIAP) chart. The DH for a
CAT I ILS approach is 200 feet or more above the touchdown zone (TDZ) or
threshold and the RVR minimums is 1,800 feet or greater. The FAA determined
that altitude and visibility values could be lowered based upon the demonstrated
skill of the flightcrew and the performance of the aircraft and ground-based
navigation equipment. The FAA has authorized certain operators to use lower-than-normal
CAT I ILS minimums at specified airports after demonstrating the ability
to conduct safe instrument approaches.
A. Copter ILS and Helicopter CAT II Approval. Copter ILS
and Helicopter CAT II approval will permit operators to fly to minimums
no lower than 100 feet height above touchdown (HAT) and/or to visibilities
no lower than RVR 1200 on published part
97 Copter ILS and CAT II ILS procedures. An unpublished DH reduction
is not authorized; e.g., the authorized DH is no lower than the relevant
minimum on the instrument approach procedure (IAP). The visibility minimum
may be reduced in accordance with part
97.3. For operations with DH below
150 feet, either a marker beacon receiver providing aural and visual
indications of the inner marker (IM) or a functioning radio altimeter (RA)
B. Small Category A Airplane CAT II Approval. Small Category
A airplane CAT II approval permits operators to fly to minimums no lower
than 100 feet height above threshold (HATh) and to visibilities no lower
than RVR 1200 on published part
97 CAT II ILS procedures. Reductions to CAT I ILS procedures are not
authorized. For operations with DH below
150 feet, either a marker beacon receiver providing aural and visual
indications of the IM or a functioning RA is required.
C. Approaches Authorized.Operators approved for CAT II approaches
conducted under part
91 may conduct any part
97 public CAT II approaches (i.e., published approaches). The specific
approaches do not have to be listed in the LOA. Small Category A aircraft,
CAT II, and Copter ILS operations to a DH below 200 feet are not authorized when
operating for compensation or hire.
4-219 APPLICATION FOR DEVIATION. Section
91.193 provides for deviations to the requirements of §§ 91.189,
91.205(f). This authority applies to the operation of small Category
A aircraft that meet the requirements listed in §
97.3. Initial contact can occur in any of several forms (telephone conversation,
in-person visit, letter, submission of an application, etc.). Before approval
of a CAT II authorization, an operator must accomplish the following:
A. Letter of Intent (LOI). The applicant should submit an
LOI (Figure 4-15, Sample Letter of Intent to Conduct Category II and/or
Copter Instrument Landing System Operations) containing specific information
about the proposed operation (e.g., the types of aircraft, Schedule of Events
(SOE), aircraft and avionics configurations, and a description of the maintenance
and inspection program). Operators should state the extent of relief requested
from the requirements of §§
91.205(f). This LOI must be submitted to the appropriate Flight Standards
District Office (FSDO).
B. FSDO Receipt. Upon receipt of an LOI requesting a small
Category A aircraft CAT II and/or Copter ILS deviation, the inspector shall
provide the applicant a copy of the small Category A aircraft approval job
aid (Figure 4-16) and inform the applicant of the requirements for approval.
Provide a copy of the LOI to the airworthiness and avionics units for timely
coordination and review. The applicant can find additional information in AC
91-16, available at
C. Application Package. When the applicant submits a completed
job aid and application package, the inspector should review the application
package for completeness, verify that the aircraft/avionics are equipped
as required in paragraph 4-222, and forward that data to the RFSD NextGen
Branch (AXX-220). RFSD concurrence is required for all small Category A
aircraft, CAT II ILS, and Copter ILS authorizations.

The Hi-Flyer Company (proposed CAT II
350 Mulberry Avenue
The Hi-Flyer Company operates a Cessna
T-210F, N6114R on a regular basis into and out of the Portland International
Jetport, Portland, Maine (PWM). Because of the predominant inclement
weather (fog) during certain months of the year, we find it necessary
to conduct instrument landing system (ILS) approaches to Runway 11 on
a regular basis.
Our experience at Portland is that we
often execute a missed approach and proceed to our alternate when ceilings
of 100 feet and RVR 1600 are predominant.
Our aircraft is equipped with dual Nav-Coms,
one glideslope receiver, a 75 MHz marker beacon receiver capable of
receiving the outer, middle, and inner markers, and an automatic direction
finder (ADF). Routine aircraft and avionics maintenance is performed
by Aero Maintenance located at Bidwell Field. Aero Maintenance is an
FAA-approved repair station.
Initially, we anticipate qualifying one
pilot, Mr. James T. Moore. His total flight time exceeds 1,800 hours,
with 350 hours in our Cessna 210 and a total of 117 hours of instrument
time. He holds Airline Transport Pilot Certificate Number 1530983 with
an airplane single-engine land rating and a Class II medical certificate
issued on (date). Mr. Moore is available for any pilot qualifications
checks the FAA may require. We would like to begin our certification
process immediately. We look forward to hearing from you.
Mr. Theodore Everberg, President

4-221 EVALUATION PROGRAM. An evaluation program
will be conducted by the operator when the aircraft flight control guidance
system required for CAT II operations is not approved under an appropriate
type certificate (TC) or Supplemental Type Certificate (STC) (part
91 appendix A). Information derived from the evaluation program should
be used to update appropriate operational procedures and techniques in the
operator’s CAT II manual. Request for deviation of the evaluation program
must be coordinated with the RFSD.
A. Evaluation Program Requirements. An evaluation program is
not required if an applicant has an aircraft in which the instruments and
equipment have been TC’d or STC’d for CAT II operations. The applicant must
present the rest of the application package for approval. This manual may
have been developed by a manufacturer and adapted for a specific operator’s
B. Demonstration of Flight Control Guidance System. The equipment
to be evaluated for approval will be the flight control guidance system.
This program provides a method of approval for those airplane owners or
operators having airplanes equipped with a flight control guidance system
that is not approved for CAT II operations under an appropriate TC or STC.
Satisfactory demonstration will show that the equipment performs to the
standards with the reliability necessary for CAT II operations.
C. Requirements for Conducting the Evaluation Program. The
procedures and requirements for conducting an evaluation program are prescribed
91 appendix A, section 3(e). The following should be considered:
1) When IM receiving equipment is to be used as the primary means
of identifying the 100-foot DH, its use will be permitted when the ground
equipment is operable. However, in the absence of operable IM ground equipment,
the lowest authorized DH is 150 feet using only a barometric altimeter.
It will be necessary to rely on barometric altimeters required by part
91 appendix A, section 2(a)(7). These altimeters will be acceptable
under that section if:
a) The altimeters and their static systems meet the requirements of
91.411 within the past 12 months; and
b) Altimeter correction data, which considers both scale error and main
landing gear wheel height of the airplane, is available to the pilot in
command (PIC). Scale error is determined by an altimeter test and inspection
43 appendix E.
2) If the first five approaches are successful, the demonstration
is complete. Otherwise, a success rate of 90 percent must be achieved for
10 approaches. If this cannot be demonstrated, the application is disapproved.
All demonstration approaches must be observed by an FAA inspector and recorded
on a suitable form developed by the operator in order to facilitate evaluation.
See Figure 4-19, Category II Approach Evaluation, for an example. A successful
approach is one in which:
a) At the 100-foot DH, the indicated airspeed and heading are satisfactory
for a normal flare and landing (speed must be plus or minus 5 knots of programmed
airspeed, but may not be less than the computed threshold speed if autothrottles
b) The aircraft at the 100-foot DH is positioned so that the cockpit
is within, and tracking so as to remain within, the lateral confines of
the runway extended;
c) Deviation from glideslope after leaving the outer marker (OM) does
not exceed 50 percent of full-scale deflection as displayed on the ILS indicator;
d) No unusual roughness or excessive attitude changes occur after leaving
the MM; and
e) In the case of an aircraft equipped with an approach coupler, the
aircraft is sufficiently in trim when the approach coupler is disconnected
at the DH to allow for the continuation of a normal approach and landing.
3) All evaluation approaches must be conducted under simulated instrument
conditions after prior arrangement with the controlling air traffic control
(ATC) facility. When conducting approaches, the operator should ask ATC
to ensure that vehicles or other aircraft on the surface will not move into
the ILS critical area. An aircraft or vehicle in the ILS critical area could
cause momentary deviations to ILS course or glideslope signals, which may
result in an unsatisfactory approach. If the FAA inspector identifies an
external condition and is reasonably sure this external condition caused
an unsatisfactory approach, that approach may be disregarded at the inspector’s
4) Although the evaluation approaches are not required to be performed
on a CAT II ILS, it is important to note that an unsatisfactory evaluation
approach is extremely difficult to attribute to small errors in ILS ground
equipment. Many CAT I ILS facilities are capable of meeting CAT II signal
standards, but are not monitored to the same tolerances as CAT II/III facilities.
An unsatisfactory approach due to a critical error incursion is something
that may be identified, but an unsatisfactory approach due to a signal or
monitor error outside CAT II limits but within CAT I limits cannot be detected
by the PIC or FAA inspector.
5) Flags, lights, aural warnings, and other displays associated
with normal and abnormal functioning of the flight control guidance system
should be evaluated to determine if they provide the crew with information
suitable for a CAT II operation.
6) The PIC conducting an evaluation program is not required to meet
the CAT II pilot requirements of § 61.67.
D. Current Form 7711, Application for Certificate of Waiver or
Authorization, Authorizations. Operators currently approved using Form
7711 for CAT II operations can continue to conduct CAT II operations under
the terms of those approvals until their normal expiration. Upon expiration,
a renewal can only be granted by issuing LOA C059, in accordance with this
