Jeppesen Charts Explained: A Practical Guide for Part 135 and Part 91 Pilots

When was the last time you briefed a Jeppesen charts approach and felt genuinely confident you weren’t missing anything? Not just running through the motions, but certain you caught every detail that mattered for that specific procedure, at that specific airport, on that specific day? Consider this: Jeppesen charts are updated every 56 days — meaning you process roughly six to seven complete revision cycles per year. Now layer in the widespread misconception that Jeppesen and FAA charts present information identically. They do not. The differences are operationally significant, and they catch experienced pilots off guard more often than anyone likes to admit.

Why Jeppesen Charts Require Dedicated Training

Jeppesen and FAA NACO charts are the two primary sources for IFR approach procedures in the United States, and both are accepted by the FAA for operational use. But they are not interchangeable in format, organization, or information presentation. Treating them as equivalent — the way many pilots do after initial instrument training — creates real gaps in aviation chart interpretation that surface during checkrides, during flight planning, and in the cockpit at the worst possible moments.

This guide is built for instrument-rated pilots operating under Part 91 and Part 135 who want to close that gap. We will walk through how to read Jeppesen charts systematically, identify where Jeppesen diverges from FAA charts in ways that directly affect flight planning and approach execution, and address the regulatory requirements that govern chart use in both operational environments. Whether you’re transitioning between chart systems, preparing for an IFR oral exam, or building a recurrent training curriculum, the goal here is the same: operationally confident Jeppesen chart interpretation grounded in regulatory compliance.

With a 56-day update cycle driving six to seven revision periods annually, systematic chart literacy is not optional. It is a core professional skill that demands structured, dedicated training.

Jeppesen Charts vs. FAA Charts: Key Differences Pilots Must Know

So what is the difference between Jeppesen charts and FAA charts? The answer goes well beyond cosmetics. While both chart systems depict IFR approach procedures and are available through electronic flight bags, the way they organize, present, and format critical information differs substantially.

Layout and Organization: Jeppesen approach charts consolidate airport-specific information differently than FAA terminal procedures publications. Jeppesen groups charts by airport within a regional binder or digital folder structure, with dedicated introductory pages covering airport-specific notes, alternate minimums, and takeoff minimums. FAA NACO charts, by contrast, embed this information within the Terminal Procedures Publication (TPP) volume, using a different organizational hierarchy. Pilots transitioning between systems often lose time searching for information that lives in a different location than expected.

Symbology: Jepp chart symbols follow Jeppesen’s proprietary legend, which differs from approach chart symbology used in FAA publications. Missed approach icons, holding patterns, procedure turn depictions, and minimum altitude representations all look different between the two systems. A thorough review of the Jeppesen chart symbol and legend guide is essential before operationally relying on Jeppesen products.

Minimums Presentation: Jeppesen approach charts present minimums in a format distinct from FAA terminal instrument procedures charts. The order of information, the way visibility and ceiling values are displayed, and how categories are arranged require deliberate study. Pilots who brief FAA charts by muscle memory will miss critical data points on a Jepp plate if they haven’t invested time learning the differences.

Both chart types are updated every 56 days. Both are accessible via properly authorized EFBs. But the way a pilot extracts and applies information from each system requires separate, dedicated proficiency.

Alternate Minimums: The Most Critical Difference

The presentation of alternate minimums is where Jeppesen and FAA charts diverge most consequentially for IFR flight planning. Jeppesen uses dedicated 10-9 and 10-9A pages that consolidate alternate minimums data into standalone reference tables. FAA charts present this information through a different methodology embedded within the TPP, using the familiar “A” symbol (triangle with an “A”) to flag non-standard alternate minimums.

Under 14 CFR 91.169, Part 91 pilots must identify and apply the correct alternate minimums when filing an IFR alternate airport. Getting this wrong — because you referenced the wrong page, misread the Jeppesen table, or assumed the FAA format applied — directly compromises flight planning accuracy. This is a frequent source of confusion and a known pain point during IFR oral exam preparation. If you’re reading Jeppesen alternate minimums for Part 91 operations for the first time, start with the 10-9/10-9A pages and cross-reference them against the specific approach you intend to use at your alternate.

How to Read Jeppesen Approach Charts: A Systematic Briefing Method

Workload management in IFR operations demands a repeatable, disciplined process for chart briefing. This is not about reading faster — it’s about reading systematically so that nothing gets skipped. The MARTHA mnemonic, recommended by the NBAA, provides exactly that structure for efficient Jeppesen approach chart briefing technique.

MARTHA stands for:

• M — Missed Approach: Review the missed approach procedure, including the missed approach point, climb instructions, and holding pattern.
• A — Altitude: Identify all altitude restrictions — initial approach fix, intermediate segment, final approach fix, decision altitude or minimum descent altitude.
• R — Radials/Radios: Note the required navaids, frequencies, course settings, and any DME or GPS requirements.
• T — Time: Confirm timing from the final approach fix to the missed approach point (critical for non-precision approaches).
• H — Heading: Verify inbound course headings, procedure turn or hold-in-lieu-of headings, and any required course changes.
• A — Airport: Review airport elevation, runway length, lighting, and any pertinent notes on the chart.

When applied to Jeppesen approach charts specifically, this structured approach helps pilots account for Jeppesen’s unique layout. Minimums, notes, and procedural details occupy different positions on a Jepp plate than on an FAA instrument approach plate. Using MARTHA forces you to find each element deliberately rather than relying on visual habit patterns developed from the other chart system. Systematic chart briefing is not a suggestion — it is essential for safe IFR operations.

Applying NOTAMs to Jeppesen Chart Data

A current Jeppesen chart is not a complete picture. Pilots must apply both FDC procedural NOTAMs and navaid/lighting/runway NOTAMs to every approach chart before commencing an IFR operation. Charts are not static documents, even when they are current within the 56-day cycle. An active NOTAM can alter minimums, close a procedure entirely, or change a critical navaid status.

During preflight, cross-reference your NOTAMs against the specific Jeppesen chart data you plan to use. Confirm navaid operational status, verify runway lighting availability (which affects published minimums), and check for any FDC NOTAMs that amend the procedure itself. This is not optional diligence — it is a regulatory obligation under 14 CFR 91.103, which requires pilots to become familiar with all available information concerning a flight before departure. The chart gives you the baseline. NOTAMs give you the reality. For the latest NOTAM information, consult the FAA Notices to Air Missions directly.

Part 91 Pilots: Jeppesen Chart Requirements and Common Mistakes

Part 91 pilots operating IFR must comply with 14 CFR 91.169 when selecting an alternate airport. This means correctly identifying and applying published alternate minimums — and as discussed, Jeppesen charts present standard versus non-standard alternate minimums in a fundamentally different format than FAA charts. If you file an alternate using Jeppesen data, you need to be reading the 10-9/10-9A pages, not guessing based on FAA chart conventions.

Here is a misconception that needs to be corrected directly: Do Part 91 pilots need special authorization to use digital Jeppesen charts? No. Standard Part 91 operators do not require OpSpec A061 or any FAA authorization to transition from paper to digital electronic flight bag charts. This requirement applies only to Part 91K, Part 125, and Part 135 operators. If you fly under standard Part 91, you can adopt digital Jeppesen charts on your EFB without a formal approval process. This is widely misunderstood, and the confusion often delays pilots from transitioning to digital formats that improve chart currency management.

That said, chart currency obligations under 14 CFR 91.103 apply regardless of format. Paper or digital, your charts must be current. Your IFR chart currency requirements do not change based on the medium — only the process for staying current does. For Part 91 operators building comprehensive IFR training programs, resources like the IS-BAO/Part 91 training package from CTS can provide a structured foundation for chart competency alongside broader operational training.

Part 135 Operations: Elevated Standards for Jeppesen Chart Use

Part 135 operators face regulatory requirements that go well beyond Part 91 standards. Weather minimums are more restrictive, equipment requirements are enhanced, and crew competency standards are formalized through recurrent training mandates. Jeppesen charts Part 135 operations training must reflect these elevated standards at every level.

Ops Spec C055 — Derived Alternate Minimums: Part 135 operators who hold Ops Spec C055 gain the capability to calculate derived alternate minimums beyond standard published values. This is a significant flight planning tool that interacts directly with Jeppesen chart data. Pilots and dispatchers must understand how to apply C055 derived minimums against the alternate minimums tables in Jeppesen’s 10-9/10-9A pages. Without this understanding, the operational advantage of holding C055 is effectively lost.

OpSpec A061 — EFB Authorization: Unlike standard Part 91 operators, Part 135 operators must obtain OpSpec A061 authorization before transitioning to digital charts. This is not a formality. A061 mandates documented procedures and training for all crew members, backup plans for device failures, procedures for device mounting and power compliance, and a defined process for chart updates. Part 135 EFB transition timelines are typically longer than Part 91K timelines, and operators often run both paper and electronic charts simultaneously during the transition period. The FAA’s Advisory Circular library contains current guidance on EFB authorization requirements for Part 135 operators.

Part 135 pilots-in-command must meet minimum experience requirements — 1,200 total flight hours, including 500 cross-country hours and 100 night hours — and must hold an instrument rating. Recurrent training every 12 months, including simulator training and proficiency checks, is mandatory under Part 135 Subpart G. Jeppesen chart competency — including alternate minimums interpretation, NOTAM application, and EFB procedures — should be embedded in those recurrent training cycles as a non-negotiable element of crew competency.

EFB Transition and Paperless Cockpit Compliance

Transitioning from paper Jeppesen charts to a digital EFB environment under Part 135 is a regulatory compliance process, not a technology upgrade. OpSpec A061 authorization requires the operator to demonstrate that crews are trained on EFB procedures, that backup protocols exist for device failure scenarios, and that chart update processes are documented and followed.

During the dual-use transition period, pilots operate with both paper and electronic flight bag charts available. This creates its own workload management challenges — knowing which source is primary, maintaining currency on both, and ensuring backup accessibility. Documented pilot chart training covering these procedures is a regulatory expectation, not a best practice suggestion. Operators should build this training into their A061 compliance documentation from day one.

Integrating Jeppesen Chart Training into Recurrent Programs

For training managers and chief pilots, the question is not whether Jeppesen chart training belongs in your recurrent program — it’s how thoroughly it’s integrated. The 12-month recurrent training cycle under Part 135 provides a natural structure for reinforcing chart competency, and dedicated modules should cover Jeppesen versus FAA chart differences, alternate minimums interpretation, NOTAM application, and EFB procedures.

IFR practical test oral exams frequently test Jeppesen-specific knowledge, making this training equally relevant for initial instrument rating training candidates. Pilots who train exclusively on FAA charts arrive at checkrides unprepared for Jeppesen-format questions. Training programs must address both chart formats to produce well-rounded, operationally prepared aviators. The NBAA Flight Operations resources offer additional industry guidance on recurrent training standards for business aviation operators.

E-learning platforms offer an efficient delivery mechanism for this content, allowing pilots to complete dedicated aviation chart interpretation modules on their own schedules while maintaining documented training records for regulatory compliance. For Part 135 operators building or refining their recurrent training curriculum, CTS aviation training packages offer structured resources aligned with Part 135 operational requirements.
