In other words, I use my knowledge of the airplane’s performance under SOP conditions to extrapolate what it’ll do if I change any of the variables. I then experiment with a new plan, adjusting my inputs if actual performance varies from expectations. In effect, I develop a technique “on the fly,” fine-tuning it on subsequent flights until it becomes a new SOP for use in this special circumstance.Writing your SOPsHow can you go about developing a set of SOPs for the airplane(s) you’re flying? Start with:Airplane checklists. Almost all airplanes have written normal, emergency and (in some types) abnormal procedures checklists in an Approved Flight Manual (AFM) or Pilots Operating Handbook (POH). These are the basis of a good set of SOPs for the actual operation of the airplane. There are several aftermarket sources for checklists for the most popular types of airplanes as well, often more detailed in some areas than those from the manufacturer.Supplemental checklists. Most additions to the basic airplane – for example, autopilots and GPSs – have a POH supplement that contains additional checklists. Educational programs should give you ideas for customizing your operations. There’s nothing that says a specific checklist is mandatory, so most pilotseventually create their own SOPs that are a synthesis from POH, supplements and other sources.Regulatory sources. Weather minima, fuel requirements, oxygen use and all manner of other decisions are made easier if you compare your alternatives to those you have under aviation regulations. Remember that most rules were written because of an accident, or the strong likelihood of a mishap.Instructor and/or type club guidance. Ask the experts in your airplane type – often an owner’s group (“type club”) or a CFI or MEI experienced in your aircraft type – what they use as SOPs.Your own experience. What works for you? As you gain experience and knowledge, you’ll undoubtedly update your personal SOPs to reflect your greater ability.vioniCs R.C.AExceeding the standardsR.C.
