Here we are all ready to depart on that long awaited family vacation. Hotel reservations and rental car arrangements are all in place. We have done our flight planning, performance planning, and have completed our preflight inspection. People and baggage are all loaded aboard our single-engine airplane. Everyone is excited as we taxi onto the active runway and apply full power for takeoff.
Even though we have briefed our passengers on having a "sterile cockpit" until we reach a safe altitude, a cheer is heard coming from the rear seats as the wheels leave the ground. What a satisfying feeling to know that all the hard work and sacrifices we have made to provide this unique opportunity to the family is truly being enjoyed. We allow a small smile to come through our "all business" pilot persona.
Wait! What's going on? Something isn't right! We're not climbing! We're losing power! We're coming down! What should I do? I think I'll... No, that won't work! Maybe I can...
Is losing engine power soon after takeoff a terrifying thought? You bet it is. This is not just a theoretical possibility that we instructors talk about. It happens many times each year. Sure, it happens to those "other pilots" who skimp on maintenance, do sloppy preflight inspections, or don't check fuel for contamination. But it also happens to conscientious pilots flying well-maintained airplanes.
So let's assume that we are doing all that is reasonably possible to prevent an engine failure. Let's make sure we take one more step and always, yes always, give a takeoff briefing at least to ourselves. Multiengine pilots have been taught to do this for a very long time, but the practice is not common among pilots of single-engine airplanes. This article will skip multi-engine operations and discuss the takeoff briefing for single-engine operations.
In order to do a proper takeoff briefing we need to study the factors involved in this particular takeoff. Therein lies the main benefit of the takeoff briefing! The takeoff briefing should include an analysis of the wind direction and velocity and what effect it will have on the takeoff. It should include the calculated ground roll and distance required to clear the standard fifty foot obstacle versus runway length and actual obstacles in the departure path. It should include the planned rotation speed given the wind, aircraft loading, etc. A point along the runway should be chosen as an abort point in the event something doesn't seem right during the takeoff run. (Yes, that's how I intended to say that. If something doesn't seem right there's usually a reason for that feeling.) The briefing should include any early turns that may be necessary due to ATC instructions, noise abatement procedures, etc. Individual pilots will choose to include various other items. Finally, it must include a plan for a low altitude engine failure and it might include more than one trigger based on the particular circumstances of this takeoff.
For example, most pilots will agree that an engine failure at less than about one hundred feet of altitude in a typical four or six passenger general aviation airplane is best handled by landing straight ahead. Of course there are exceptions to every rule. Would we continue straight ahead into a large propane tank when a 10 degree turn would put us into small trees? Of course not. But as the altitude increases we enjoy more options. What if the engine quits at 300 feet? Where will we go? Back to the airport? Probably not but there might be an empty field thirty to forty-five degrees off the nose. Our best course of action will depend on the terrain and on our altitude.
So perhaps our takeoff briefing will include pre-made decisions on what to do if the engine quits at less than 100 feet, between 100 feet and 500 feet, between 500 feet and 1000 feet, etc. We can choose our altitude bands depending on our airplane, today's wind and density altitude, and the particular airport environment.
A great tool for learning more about the airport environment is Google Earth. A small program downloaded onto our computer lets us examine, from various angles, the terrain and obstacles around an airport. This can be extremely valuable graphic information when used in conjunction with traditional tools such as the Airport/Facility Directory and other government publications.
So let's make a commitment to include the possibility of an engine failure into our takeoff planning and to verbalize the plan just prior to executing the takeoff. Yes, it's OK to talk to yourself!
