What is NATIP?

NATIP is the Naval Aviation Technical Information Product, the Naval Air Systems Command (NAVAIR) publication that carries the technical data and limitations for a naval aircraft's weapons, avionics, and mission systems. NAVAIRINST 13034.1D, the NAVAIR flight clearance policy dated March 15, 2010, describes it as one of the two forms a permanent flight clearance takes, the other being the NATOPS flight manual. CNAF M-3710.7, the NATOPS General Flight and Operating Instructions Manual dated February 7, 2025, treats NATIP as a sibling product: hosted on the same website, reviewed against the same manuals, drawn on by NATOPS checklists, and testable on a NATOPS evaluation. This page sets out what the public documents say about NATIP, how it differs from NATOPS and from the tactics publications, who produces it, and how it changes. For the program it sits beside, see what NATOPS is.

What NATIP stands for and what it holds

The 2009, 2016, and 2025 editions of the Navy's general NATOPS manual expand the acronym the same way. The glossary of the February 2025 CNAF M-3710.7 reads "NATIP. Naval aviation technical information product." The May 5, 2016 edition of CNAF M-3710.7, hosted by Headquarters Marine Corps Aviation, and the 2009 OPNAVINST 3710.7U use the same expansion.

What the product holds is spelled out in the flight clearance instruction. NAVAIRINST 13034.1D says the NATIP provides critical technical data and limitations for all weapons, weapon systems, avionics, and mission systems required for the operator to safely and effectively employ the aircraft's weapon and mission systems. The instruction adds that NATIP primarily supports standardized aircraft weapon and mission system configurations operated within standard limits or operating envelopes, though a NATIP may include combinations of standard and non-standard configurations and limits.

The reason the product exists is also stated. The instruction says NATIP is "the technical foundation, limitations, and safety of flight information" on which the aircraft tactics publications are developed, and elsewhere calls it the primary technical reference upon which tactics are developed. A NATIP is therefore not a how-to-fight document. It is the engineering envelope inside which the fighting is planned.

NATIP versus NATOPS

Searchers type "natip vs natops" because the two travel together. NAVAIRINST 13034.1D draws the line in one paragraph. Permanent flight clearances come in two forms, NATOPS and NATIP, or a legacy Tactical Manual where one still applies. The NATOPS provides standardized aircraft operating procedures, limitations, technical data, and training requirements necessary for safe and effective operation of the aircraft model or aviation support activity. The NATIP provides the technical data and limitations for the weapons, weapon systems, avionics, and mission systems. In short, NATOPS covers flying the aircraft and NATIP covers employing what the aircraft carries.

CNAF M-3710.7 states the same division from the operator's side. Paragraph 7.1.1 says every Navy and Marine Corps aircraft shall have an airworthiness certification in the form of a flight clearance issued by Commander, Naval Air Systems Command (COMNAVAIRSYSCOM) or an airworthiness assessment, and that permanent flight clearances are issued for standardized configurations "in the form of a NATOPS and NATIP (when applicable)." The qualifier matters: NAVAIRINST 13034.1D says NATIPs are issued primarily for aircraft systems that have a corresponding AIR NTTP.

The two products share a legal effect. Under paragraph 7.1.1, an aircraft operated outside the limits or procedures of an existing promulgated NATOPS or NATIP, in a nonstandard configuration, or with nonstandard techniques requires a modified flight clearance, which may take the form of a NATOPS or NATIP change or an Interim Flight Clearance (IFC). The glossary of CNAF M-3710.7 defines a flight clearance as a temporary airworthiness approval that provides operating limits "pending issuance of the technical directive or change to the NATOPS, NATIP, or tactical manuals." Under paragraph 7.1.1, operating outside a NATIP limit requires a modified flight clearance, just as operating outside a NATOPS limit does.

NATIP versus NTTP and the old TACMAN

The second comparison searchers make is with the tactics publications. NAVAIRINST 13034.1D gives the history. In 2002 the Aircraft Tactical Manual (TACMAN) program was restructured into two programs: the Aircraft Naval Tactics, Techniques, and Procedures (AIR NTTP) program and the NATIP program. OPNAVINST 3510.15A designated AIR-4.0P, the NAVAIR airworthiness office, as the NATIP program manager and the Naval Strike and Air Warfare Center as the AIR NTTP program manager. After the split, NATIP carries the technical foundation and limitations, and the AIR NTTPs carry the tactics developed on that foundation.

The instruction describes the transition rules. NAVAIR remained responsible for sustaining the technical data in legacy TACMANs and for promulgating changes to the appropriate sections through the flight clearance process until each was converted. A TACMAN interim change was initiated by a flight clearance request and normally issued by naval message with replacement pages made available electronically; a TACMAN change was a sizable update, usually prompted by original equipment manufacturer contract deliverables. Legacy TACMANs were to be converted to AIR NTTP and NATIP.

CNAF M-3710.7 shows where the three products meet in practice. Paragraph 2.2.2 requires the NATOPS Program Manager for each aircraft to conduct a continuous review of existing publications, including NATOPS manuals, Maintenance Instruction Manuals, Allied Tactical Publications (ATPs), Naval Warfare Publications, Naval Tactics, Techniques, and Procedures (NTTPs), and NATIPs, to discover any conflicts, and to submit change recommendations through the Airworthiness Issue Resolution System (AIRS) to resolve them. The 2009 instruction placed the same duty on the Program Manager in the same words. A conflict between a NATOPS procedure and a NATIP limit is, by design, somebody's job to find.

Who produces NATIP

NAVAIRINST 13034.1D says that, per OPNAVINST 3510.15A, AIR-4.0P is responsible for the management of the NATIP program, and that the technical content, style, and format of a NATIP shall be in accordance with the NATIP Program Management Guide, which the instruction calls the primary NATIP working document for programmatics.

The 2025 general manual names a different office for these duties. CNAF M-3710.7 paragraph 2.2.1 assigns the NATOPS Products Administrator role to the NAVAIR Airworthiness and CYBERSAFE Office (ACO), and paragraph 2.2.2 gives that office the duty to maintain the Airworthiness website "to provide NATOPS and other airworthiness and flight clearance products (including Interim Flight Clearances and Naval Aviation Technical Information Product (NATIP)) to the Fleet." The 2016 edition carries the same duty, numbered as item 13 of the administrator's list. The 2009 instruction, in its flight clearance paragraph, named NAVAIR 4.0P as the office that determines whether a modified flight clearance takes the form of a NATOPS or NATIP update or an IFC.

Like NATOPS, a NATIP matures in stages. NAVAIRINST 13034.1D describes three. A Draft NATIP, begun by new acquisition or major upgrade programs in support of research, development, test, and evaluation, contains approved engineering data and limits, is restricted to the test community, and is used under an IFC during developmental test. A Preliminary NATIP, required before Operational Test Readiness Review, contains mature engineering data, configurations, limits, interfaces, and operating steps for the operational test community, again under an IFC. An Approved NATIP carries a NAVAIR-endorsed letter of approval authorizing fleet use and an AIR-4.0P release message that identifies the current NATIP by calendar date. The structure mirrors the Draft, Preliminary, and Promulgated categories that CNAF M-3710.7 paragraph 2.3.3 sets for NATOPS products.

Where NATIP lives: the Airworthiness website

CNAF M-3710.7 paragraph 2.3.1 lists the administrative tools of the NATOPS program and names the Airworthiness website, at airworthiness.navair.navy.mil, as the primary information conduit for all participants. The paragraph says NATOPS products, interim changes, the Program Manager's Handbook, AIRS, OPNAVINST 3710.7, the NATOPS Status Report, and the Review schedule are available there, and then adds that NATIP and Interim Flight Clearance information is also located at the website. The 2009 instruction said the same and described NATIP in its flight clearance paragraph as a "Web-based product."

NAVAIRINST 13034.1D is specific about the fleet's access. Approved NATIP shall be accessed by fleet users via an AIR-4.0P approved web-based electronic library, with the Airworthiness website given as the example. When a NATIP Update is approved, the updated content is incorporated into the NATIP immediately and promulgated to the fleet through the same library. No NATIP text is quoted on this page.

NATIP on a NATOPS evaluation

A pilot preparing for the annual NATOPS check may be tested on NATIP. CNAF M-3710.7 paragraph 2.7.1, which introduces the evaluation program, says "NATIP data is testable during NATOPS evaluations" at the discretion of the Model Manager Unit (MMU). The rule is repeated for each phase. Paragraph 2.7.2.4 says the areas evaluated in the ground phase, the open book, closed book, and oral examinations, are set by the aircraft's NATOPS manual, and that NATIP material may be included in the ground evaluation at the MMU's discretion. Paragraph 2.7.2.5 says the same for the evaluation flight. The 2009 instruction carried all three provisions.

NATIP as a source for checklists

NATIP also reaches the cockpit through the pocket checklist. Paragraph 2.3.2 of CNAF M-3710.7 defines NATOPS Checklists as abbreviated excerpts of the flight manual for use while airborne and says the information in a NATOPS checklist shall be derived from the flight manual, other approved NATOPS, or NATIP. The 2009 wording was looser, "other approved NATOPS or related source (e.g., NATIP)," and the 2016 and 2025 editions name NATIP outright. A weapon system step on a NATOPS checklist can therefore trace to a NATIP rather than to the flight manual, which is one reason the Program Manager's conflict review covers both.

NATIP in a flight clearance message

A public interim flight clearance shows how NATIP is cited in practice. The Multiplatform Interim Flight Clearance for Use of Portable Electronic Tablets in Flight, a 2018 COMNAVAIRSYSCOM message hosted by Training Air Wing FIVE, sets the aircraft configuration and loading for tablet carriage "IAW applicable T/M/S NATOPS, NATIP" and the limitations as the most restrictive of the applicable NATOPS, NATIP, and the clearance itself. The message cites NAVAIRINST 13034.1F, dated June 30, 2016, as the governing airworthiness policy, which shows that the flight clearance instruction has been revised at least twice since the 2010 edition quoted on this page.

The maintenance program recognizes the same clearance family. COMNAVAIRFORINST 4790.2E, the Naval Aviation Maintenance Program dated 28 October 2024, says an unmanned aircraft control station must complete its NATOPS preflight and system checks before use and that, for systems without a NATOPS, the approved preflight procedures identified in the IFC must be followed. The NAMP's Technical Data Management procedure, paragraph 10.8, lists CNAF M-3710.7 among its references, so the maintainer's technical data rules and the aircrew's flight clearance products are formally linked.

What to check

• Is the limit or data point in question in the NATOPS flight manual, the NATIP, or an Interim Flight Clearance? NAVAIRINST 13034.1D assigns aircraft operation to NATOPS and weapon and mission systems to NATIP.
• Is the NATIP cited by calendar date? The instruction says the AIR-4.0P release message identifies the current NATIP that way, and a NATIP Update is issued by message.
• Is the NATIP Draft, Preliminary, or Approved, and if not Approved, which IFC authorizes its use?
• Has the aircraft's NATOPS Program Manager reviewed the NATIP against the NATOPS manual and NTTPs for conflicts, as CNAF M-3710.7 paragraph 2.2.2 requires?
• Does a quoted tactic come from an NTTP, and does its underlying limit trace to a NATIP?
• Which edition of NAVAIRINST 13034.1 is cited? The copy quoted on this page is 13034.1D of 2010; the 2018 tablet clearance cites 13034.1F of 2016.

Azcuna's ELLMENT, the E-2D Large Language Model Entity, was proposed to NAVAIR PMA-231 under Navy SBIR Phase I topic DON26BZ01-NV010. The prototype, built at private expense on publicly available doctrine, answers with a page-level citation and refuses when the documents do not support an answer. The proposal has been submitted.

Questions people ask

What does NATIP stand for?

NATIP stands for Naval Aviation Technical Information Product. The glossary of CNAF M-3710.7, the NATOPS General Flight and Operating Instructions Manual dated February 7, 2025, expands the acronym that way, as did the 2009 OPNAVINST 3710.7U and the 2016 edition of CNAF M-3710.7. NAVAIRINST 13034.1D, the NAVAIR flight clearance policy, describes the NATIP as the product that provides critical technical data and limitations for weapons, weapon systems, avionics, and mission systems.

What is the difference between NATIP and NATOPS?

NAVAIRINST 13034.1D says permanent flight clearances come in two forms. NATOPS provides standardized aircraft operating procedures, limitations, technical data, and training requirements for safe and effective operation of the aircraft. NATIP provides the critical technical data and limitations for weapons, weapon systems, avionics, and mission systems the operator needs to employ them safely and effectively. CNAF M-3710.7 paragraph 7.1.1 puts it the same way: permanent flight clearances are issued in the form of a NATOPS and a NATIP when applicable.

Is NATIP a tactics manual?

No. NAVAIRINST 13034.1D says the Aircraft Tactical Manual program was restructured in 2002 into the Aircraft Naval Tactics, Techniques, and Procedures (AIR NTTP) program and the NATIP program. NATIP is the technical foundation, limitations, and safety of flight information on which the AIR NTTPs are developed, and the primary technical reference upon which tactics are developed. The tactics themselves sit in the NTTPs, which the instruction said were managed by the Naval Strike and Air Warfare Center.

Who produces NATIP?

The Naval Air Systems Command. NAVAIRINST 13034.1D says that, per OPNAVINST 3510.15A, AIR-4.0P is designated the NATIP program manager and is responsible for the management of the NATIP program, with content, style, and format governed by a NATIP Program Management Guide. CNAF M-3710.7 assigns the NATOPS Products Administrator role to the NAVAIR Airworthiness and CYBERSAFE Office and gives that office the duty of maintaining the Airworthiness website to provide NATOPS and other flight clearance products, including NATIP, to the fleet.

Where is NATIP hosted?

On the NAVAIR Airworthiness website. CNAF M-3710.7 paragraph 2.3.1 says NATIP and Interim Flight Clearance information is located on the Airworthiness website at airworthiness.navair.navy.mil, the primary information conduit for the NATOPS program. NAVAIRINST 13034.1D says approved NATIP shall be accessed by fleet users through an AIR-4.0P approved web-based electronic library, and the 2009 OPNAVINST 3710.7U called NATIP a web-based product, located on the same website as NATOPS products and interim changes.

Can NATIP be tested on a NATOPS evaluation?

Yes. CNAF M-3710.7 paragraph 2.7.1 says NATIP data is testable during NATOPS evaluations at the discretion of the Model Manager Unit. Paragraph 2.7.2.4 adds that NATIP material may be included in the ground evaluation, the open book, closed book, and oral examinations, and paragraph 2.7.2.5 says it may be included in the evaluation flight, both at the Model Manager Unit's discretion. A pilot preparing for an annual NATOPS check may therefore be examined on weapon and mission system data from the NATIP.

How is NATIP changed?

NAVAIRINST 13034.1D says approved NATIP are changed by a NATIP Update, initiated by a flight clearance request and normally issued by a naval message that identifies the current NATIP by calendar date, with the updated content incorporated and promulgated through the web-based library. CNAF M-3710.7 paragraph 7.1.1 says operating outside the limits or procedures of a promulgated NATOPS or NATIP requires a modified flight clearance, which may take the form of a NATOPS or NATIP change or an Interim Flight Clearance.

Can a NATOPS checklist contain NATIP data?

Yes. CNAF M-3710.7 paragraph 2.3.2 says information in a NATOPS checklist shall be derived from the NATOPS flight manual, other approved NATOPS, or NATIP. The 2009 OPNAVINST 3710.7U used the phrase other approved NATOPS or related source, giving NATIP as the example. The NATOPS Program Manager must also review NATIPs, along with Allied Tactical Publications, Naval Warfare Publications, and NTTPs, for conflicts with the NATOPS manuals and submit change recommendations through AIRS to resolve any conflict.
