Operating Practices

Master your aircraft with PMOPA's Operating Practices. 

Standardization is the foundation of aviation safety. The PMOPA Operating Practices (POPs) represent our community’s best practices for operating the M-Class fleet. Derived directly from the POHs for each aircraft type, and compiled with the collective experience of senior members of the M-Class community, these profiles are designed to establish a safe, consistent, repeatable flow during critical phases of flight. 

By flying a standardized profile, pilots internalize a baseline of "normal." When normal is strictly defined, it is not only easily repeatable, but also any deviation—whether mechanical, environmental, or operational—becomes immediately obvious. This helps the pilot promptly recognize the anomaly and make appropriate corrections in a timely manner.

Aeronautical Decision Making (ADM) and Deviations

PMOPA's Operating Procedures are designed for a normally operating aircraft, within limitations and under typical flight conditions. Always keep in mind that aviation is dynamic. Sound ADM requires the PIC to recognize when environmental or operational factors dictate a departure from the standard profile.

Pilots must be prepared to modify these baselines when encountering situations such as:

• Known or forecast icing conditions, or active airframe icing.
• Strong crosswinds, wind shear, or high gust spreads.
• Significant convective or mechanical turbulence.
• Exceptionally short or long runway operations.
• Approaches with glidepaths significantly steeper or shallower than standard 3-degree angles.
• Any abnormal or emergency checklist execution.

1. Supplemental Advisory Content Only (Not Operational Procedures)

The information, operational techniques, safety suggestions, and "best practices" contained herein are contributed solely by individual aircraft owners and pilots sharing personal experiences. This content is intended strictly for educational, informational, and recreational purposes. 

• This information does NOT constitute official operational procedures, approved flight training curriculum, or official maintenance instructions.
• The strategies discussed here have not been tested, engineered, or certified by the aircraft manufacturer, the Federal Aviation Regulations (FARs), the Federal Aviation Administration (FAA), or any other civil aviation authority.

In all circumstances, the official, government-approved documentation for your specific aircraft takes absolute legal and operational precedence. You must NEVER substitute advice from this publication for official data. If any information in this document conflicts in any way with official sources, you must disregard this document entirely. Official sources include, but are not limited to:

• The FAA-approved Pilot’s Operating Handbook (POH) or Airplane Flight Manual (AFM).
• Factory Service Bulletins, Service Letters, and Airworthiness Directives (ADs).
• Federal Aviation Regulations (FARs) and the Aeronautical Information Manual (AIM).

3. Sole Responsibility of the Pilot in Command (PIC)

Under FAR § 91.3 (or applicable local aviation laws), the Pilot in Command (PIC) is directly responsible for, and is the final authority as to, the operation of the aircraft. Every aircraft, engine, and environmental situation is unique. The application of any "best practice" or technique found in this publication is done at the sole discretion and risk of the PIC. It is the PIC’s exclusive duty to evaluate whether any advice is safe, applicable, and lawful for their specific flight profile, aircraft configuration, and atmospheric conditions.
