1. Introduction
This document is a community-made reference guide for Falcon BMS 4.38.1, focused on practical use of three HOTAS controls: the Target Management Switch (TMS), the Display Management Switch (DMS), and the Countermeasures Management Switch (CMS). The fundamental behavior of these switches has remained consistent since at least Falcon BMS 4.36, making this guide applicable to virtually any Falcon BMS user.
This work is entirely unofficial. The author is not affiliated with Benchmark Sims, MicroProse, any real-world air force, or any aircraft or weapons manufacturer. All interpretations, simplifications, errors, and omissions are solely the responsibility of the author and must not be attributed to the Falcon BMS development team or any real-world organization.
Nothing in this document should ever be used for real-world operations, training, or procedures.
1.1 Sources and references
This guide is grounded in the following primary Falcon BMS documents:
- TO BMS 1F-16CMAM-34-1-1 (Dash-34, Change 4.38) — Avionics and Nonnuclear Weapons Delivery Flight Manual. Primary source for HOTAS behavior, SOI logic, and weapons employment.
- BMS Training Manual 4.38.1 (October 2025) — Training missions and learning objectives. Used for practical cross-references and recommended training progression.
All technical claims in this guide are cross-referenced to these sources. Where specific sections are cited, the notation Dash-34 § X.Y.Z refers to Dash-34 section X.Y.Z.
1.2 Scope and purpose
The guide organizes TMS, DMS, and CMS behavior by operational context: master mode, sensor configuration, and weapon employment scenario, presenting each switch input and its effect in mode-based tables. Other systems, avionics, and controls are described only when essential to understanding the behavior of these three switches.
Knowledge of basic F-16 operation and familiarity with master modes (NAV, A-A, and A-G) is assumed. This is not a comprehensive HOTAS or avionics manual and does not replace the Dash-34 or Training Manual.
1.3 Document structure and how to read it
1.3.1 Chapter overview
This guide is organized into six chapters:
- Chapter 2 establishes the conceptual framework for all three switches: Sensor of Interest (SOI), master modes, and a high-level overview of DMS, TMS, and CMS.
- Chapters 3–5 cover one switch each — DMS (Chapter 3), TMS (Chapter 4), and CMS (Chapter 5) — combining narrative explanation with standardized HOTAS tables organized by master mode and sensor configuration.
- Chapter 6 is a quick reference chapter, combining the HOTAS tables from Chapters 3–5 with switch diagrams for immediate visual lookup.
1.3.2 Table format
Chapters 3, 4, and 5 use a standardized seven-column table format to document switch behavior. Each row describes a single switch action in a specific operational context:
| Column | Description |
|---|---|
| Mode | Operational context: master mode, sensor state, or weapon configuration |
| Dir. | Switch direction: Up, Down, Left, or Right |
| Act. | Actuation type: Short press or Long press |
| Function | Brief name of the function performed |
| Effect / Nuance | Detailed explanation of system behavior, constraints, and tactical considerations |
| Dash34 | Cross-reference to Dash-34 section(s) |
| Train. | Recommended BMS training mission number(s) |
1.3.3 Typographic conventions
Three inline formatting conventions are used consistently throughout the guide:
- Bold identifies the three HOTAS switches covered by this guide and their directions when referenced in prose: TMS Up, CMS Down, DMS Left.
Monospacereproduces strings exactly as they appear on a system display or are generated as system voice messages:DISPENSE RDY,COUNTER,STBY,AVNC.- Italic marks a technical distinction where sentence structure alone does not sufficiently convey the critical information.
