RESPECTING STANDARD OPERATING PROCEDURES (SOPs) & LIMITATIONS
Standard Operating Procedures (SOPs) are fundamental to ensuring safe aviation operations. Adhering to these procedures plays a crucial role in enhancing flight safety and mitigating the risk of accidents.
01 INTRODUCTION
Strict compliance with SOPs, including the diligent use of normal checklists, significantly enhances the safety of both ground and flight training by preventing pilot errors and effectively managing operational threats.
02 DATA
Research has highlighted various factors contributing to approach and landing accidents. The table below illustrates the percentage of studied accidents linked to issues related to understanding or following SOPs. The data clearly indicate that many accidents stem from SOP-related challenges.
Factors Related to SOP Understanding and Adherence |
Percentage of Events |
|---|---|
| Omission of action or inappropriate action | 72% |
| Nonadherence to criteria for stabilized approach | 66% |
| Inadequate coordination, cross-checking, and backup | 63% |
| Insufficient horizontal or vertical situational awareness | 52% |
| Inadequate understanding of prevailing conditions | 48% |
| Slow or delayed action | 45% |
| Deliberate nonadherence to procedures | 40% |
| Incorrect or incomplete pilot/controller communication | 33% |
| Ineffective interaction with automation | 20% |
| Absence of go-around when required | 17% |
03 MANUFACTURER & ATO PROVIDED SOPs
SOPs outlined in the Pilot Operating Handbook (POH) by manufacturers and in the ATO's Visualized Flight Maneuver Manual are designed to:
- Reflect the cockpit design and operating philosophies of the manufacturer.
- Address training and operational limitations specified in the respective manuals.
- Promote adherence to various aircraft, training, and local limitations, including rotation and climb SOPs (such as speeds), landing techniques (including configuration and speed limitations), and minimum altitudes for certain maneuvers like stalls and spins.
- Standardize flight training across different ATO environments while ensuring that all safety-related actions are followed.
- Incorporate lessons learned from past training experiences.
- Integrate experience gained during training and flight operations.
04 TRAINING ASPECTS
The disciplined application of SOPs and normal checklists should begin at the outset of any training course. Habits formed during initial training can have lasting repercussions.
Whenever possible, discuss not only the reasons behind rules and procedures but also the consequences of non-compliance. Allowing relaxed adherence to SOPs or checklists during initial or recurrent training can encourage future deviations. We must all remember: Train as you fly, fly as you train!
05 FINAL ATO HIGHLIGHTS
- Compliance with SOPs and limitations forms the foundation of aviation safety.
- SOPs are designed to guide us toward the most efficient and safe outcomes.
- The ATO motto is to prioritize safety by using SOPs and respecting limitations, as they provide the best chance for achieving safe operations. However, if circumstances change, we must be prepared to adapt while keeping SOPs and regulations in mind.
- Always exercise sound airmanship, critical thinking, and judgment. For example:
- Takeoff Run: Refuse ATC instructions if directed to take off from a position with insufficient runway length.
- Cruise Altitude: Reject ATC instructions to maintain an altitude that falls below your minimum safe altitude or places your aircraft on a collision course.
- Crosswind during Takeoff/Landing: Cancel your flight planning if headwind or crosswind conditions exceed safe limitations.
- Diversion: Make timely diversion decisions in response to deteriorating weather, fuel starvation, or engine issues. Do not succumb to the mentality that "it won't happen to me," as unforeseen situations require immediate corrective actions.
