b. Other Navigation Equipment Required. Aircraft employing multi-sensor equipment for IFR navigation must also be equipped with an approved and operational alternate means of navigation appropriate to the intended route to be flown. Within the contiguous United States, Alaska, Hawaii, and surrounding coastal waters, this requirement may be met with an operational, independent VOR receiver, although data from this receiver can provide an input to the multi-sensor equipment. For oceanic and remote operations, an alternate means of navigation is required unless the multi-sensor equipment incorporates within itself a sensor approved individually for the particular area of operations (some oceanic airspace may require additional redundancy).
c. Alternate Airport Requirements. An alternate airport (if required by the applicable operating rules) must be served by an approved instrument approach procedure based on a navigation system other than GPS or Loran-C and the aircraft must be properly equipped to conduct that approach.
d. Operational Area. Operators and their flight crews must consult the approved flight manual supplement for their aircraft to determine approved operational areas that may apply to particular systems and/or sensors. Flight crews must be aware that operational areas for different systems/sensors may be different, and the appropriate operating area(s) for a particular system can only be determined by reference to the approved flight manual supplement or other FAA approved documents.

Appendix 1 Par 1 1 APPENDIX 1. PROCEDURES FOR OBTAINING FAA APPROVAL OF FOLLOW-ON
MULTI-SENSOR EQUIPMENT INSTALLATIONS FOR IFR/VFR OPERATIONS BY FAA FORM 337
1. FOLLOW-ON MULTI-SENSOR EQUIPMENT INSTALLATIONS LIMITED TO VFR USE ONLY. Approval of follow-on multi-sensor equipment installations limited to VFR use only (where the initial approval was accomplished using the TC or STC process) are normally obtained using FAA Form 337 approved by the responsible Flight Standards District Office (FSDO). Such installations can usually be approved for return to service by one of the entities noted in 14 CFR part 43; i.e., repair station, manufacturer, holder of an inspection authorization, etc., provided the installation:
a. General Installation Methods. Conforms to the acceptable methods, techniques, and practices contained in AC 43.13-1A, Acceptable Methods, Techniques and Practices - Aircraft Inspection and Repair, and AC 43.13-2A, Acceptable Methods, Techniques, and Practices - Aircraft Alterations.
b. Installation Criteria. Is in accordance with the criteria specified in paragraph 8c(1)(ii) of this AC. A certification from the manufacturer to confirm that the en route/terminal accuracy requirements of paragraph 6 and ground accuracy test requirements of paragraph 8c(1)(iii) have been met should be provided. This certification can be accomplished by reference to the first time TC/STC approval.
NOTE: Limited test data may be required to verify/demonstrate that the applicable requirements have been satisfied.
c. Aircraft Flight Manual Supplement/Placard(s). Except for those installations where placards address required limitations, an airplane or rotorcraft flight manual supplement (or supplemental flight manual) prepared by the applicant and containing at least the following information must be presented for FAA approval. The proposed flight manual supplement (or supplemental flight manual) is submitted for approval along with the other data associated with the installation.
(1) Equipment operating limitations.
(2) Emergency/abnormal operating procedures (if applicable).
(3) Normal procedures for operating the multi-sensor equipment and any interfaced equipment. (May be provided in a pilot’s guide that is referenced in the flight manual supplement.)
(4) General description of system (or reference to a pilot’s guide that provides an equipment description).
Appendix 1 2 Par 1
d. Functional Flight Evaluation. A functional flight evaluation covering the items listed in paragraph 8c(2)(iii) is accomplished by the installer. The results of this evaluation are included with the data provided to the FSDO.
2. FOLLOW-ON MULTI-SENSOR EQUIPMENT INSTALLATIONS FOR IFR USE.
Approval of follow-on multi-sensor equipment installations for IFR use (where the initial approval was accomplished using the TC or STC process) may be obtained using an FAA Form 337 approved by the responsible FSDO.
a. Data Submitted by the Applicant. Alteration data for the equipment installation is submitted with a properly executed FAA Form 337, and a certification from the manufacturer to confirm that the accuracy requirements of paragraph 7a and ground accuracy test requirements of paragraph 9c(1)(iii) of this AC and system performance specifications of TSO- C115a or b have been met. (This certification can be accomplished by reference to TSO-C115a or b approval and the original TC/STC approval.) The FAA Form 337, along with all required data pertaining to the installation, should be submitted to the responsible FSDO
b. Additional Data That May be Required. If required by the FSDO (or an ACO when consulting with the FSDO when reviewing the data/conducting necessary tests requested by the FSDO) approving the technical data/installation, the applicant may also be required to furnish a copy of the equipment data (for equipment not produced under TSO-C115a or b authorization), manufacturer’s operating and installation instructions, fault analysis for installation, installation details and/or photographs, structural substantiation, system wiring diagrams, and ground test evaluation results.
c. Aircraft Flight Manual Supplement. An airplane or rotorcraft flight manual supplement (or supplemental flight manual) prepared by the applicant and containing at least the following information must be presented for FAA approval. The proposed flight manual supplement (or supplemental flight manual) is prepared using the guidance contained in Appendix 2 and submitted to the FSDO.
(1) Equipment operating limitations.
(2) Emergency/abnormal operating procedures.
(3) Normal procedures for operating the multi-sensor equipment and any interfaced equipment. (May be provided in a pilot’s guide that is referenced in the flight manual supplement.)
(4) General description of system (or reference to a pilot’s guide that provides an equipment description).
d. Functional Flight Evaluation. A functional flight evaluation covering the items listed in paragraph 9.c.(2)(iv) is accomplished. The inspector may authorize the installer to
Appendix 1 Par 2 3 conduct the flight evaluation. In situations where additional FAA evaluation is necessary, required flight evaluations will be conducted by the cognizant ACO or, when authorized, by a Flight Test Pilot Designated Engineering Representative (DER) in accordance with the procedures used by the ACO.
Appendix 2 Par 1 1 APPENDIX 2. SAMPLE AIRPLANE FLIGHT MANUAL SUPPLEMENT (FAA Form 337 Approval Process).
1. The following sample Airplane Flight Manual Supplement (AFMS) is provided as an example of the format to be used and information to be included when preparing required supplements. An AFMS must follow the organization of the flight manual being supplemented.
