THE COMMUNITY OF FLYING by Josh Smith, General Manager
Happy spring to all of the members of West Valley Flying Club. I certainly hope everyone got their stimulus check… now let’s go out and spend it on some flying.
We are looking at adjusting the base rate. I am spending the first part of the month weighing different options with fleet owners and other forums for gathering data and feedback and will put forward whatever changes are decided upon by the end of June. Any changes to the base surcharge will result in changes to the base rental rates. These changes will be put into ecffect by July 1.Who knows - maybe oil will drop to $50/barrel by then.
With regard to Diamond Aircraft, for anyone who has been following the aviation blogosphere and various web pages, the engine supplier to the Diamond twin-star (Thielert) is going through a financial re-organization. This is of course creating a supply chain problem, and one of the two fleet twins has been down for an extended period of time. The club is following the news very closely and is going to work with the owner, Diamond, etc., to see if we can create a positive path forward with these aircraft.
The website was moved from one server to another. I apologize for any issues that may have arisen. It appears that most major functionality is working normally. There are a few issues that still remain on the fix-it list. I will continue to push through these as well as put in some much needed enhancements. If you find any issues, or would just like to see some improvements, please forward them to the webmaster at webmaster@wvfc.org Our goal is to completely re-do the website by next fiscal year.
I would of course like to draw people’s attention to the new safety forum on the BBS. My goal is publish a new string every week that is directly related to a reason that an aircraft has been damaged. This had not been a great year for WVFC and accidents. We need to all do out part to fly the aircraft as smartly and safely as we can. Remember that 95% of the reason a plane is damaged, or lost, or worst of all someone is injured is due to the pilot and not the plane. We should always been in a constant mode of learning.
We are changing the format for the newsletter; if you have thoughts or concerns please email them to Whatsup@wvfc.org
For the most current listing of fleet aircraft that are for sale please go to: Fleet Aircraft for Sale This is may be the last year you will be able to take advantage of the bonus depreciation; that combined with a buyer’s market makes it a good time to get into an aircraft.
Thanks for your support.
Josh
Board Elections If you have any questions pleas send an E mail to: Vote @wvfc.org
The board elections are coming up in June. For details on the process and an overview of the schedule please see the elections central website at www.wvfc.org/mem/v/election.html. Becoming a board member is a great way to participate and it is a good experience. If you have one particular agenda item, then I would suggest forwarding that item to the existing board rather than going through the entire elections process. For anyone who is interested, existing board members would be more than willing to make time to go over current strategic plans, an overview of the history, and review significant board history to give potential new members some insight to the inner workings.
We have received unopposed nominations for the following people to serve on the board:
Please come to meet them at the remaining “meet the candidate” sessions:
Finally, remember that votes will be accepted starting at 00:01 AM on Monday, June 16th and ending at 11:59 PM on Sunday, June 22nd. You can vote via the website, regular mail or in person.
Flight Safety Part II – Head work - HUMAN FACTORS IN AIRPLANE ACCIDENTS by Lucy Geever, WVFC Chief Pilot chiefpilot@wvfc.org
This is a continuation of last month’s newsletter article on Human Factors in Airplane Accidents. I promised to report back with incidents and accidents specific to the Club. When members damage an airplane I ask the member to do an assignment for me. I ask them to write up what happened, why it happened and how to prevent future damage. I also ask them to try and reconstruct the accident chain.
Our first accident for review involved a meticulous private pilot with 200 hours. He flies regularly about four hours per month. His plan was to fly from KPAO to 0Q5 (Shelter Cove, CA). On board were the pilot and one passenger.
It was a glorious April day in northern California. Visibilities were 20+ miles, winds were calm and temperatures were above normal. The accident happened on take-off. The pilot departed Runway 13 at E55 (Ocean Ridge, CA). The pilot rotated at 55 knots and the airplane lifted off the runway but did not appear to be climbing. The stall warning horn sounded. The pilot reduced the power and landed, aborting the take-off. He applied brakes, but the airplane overran the end of the runway, slid down a hillside, and collided with trees. The pilot reported there were no mechanical malfunctions or failures. Let us back up and see what happened earlier that day.
The pilot completed very detailed planning that included an alternate. He had gotten a comprehensive weather briefing and had on board all of the information he thought he would need for his flight. Overall, I believe any DPE would have considered his pre-flight planning comprehensive.
A link – the unexpected – a passenger need and a deviation from the plan.
The passenger had a physiological need; he had to relieve himself. A usual part of this pilot’s preflight is to ensure that he and his passenger use the bathroom. This had never been a serious issue in the past and the pilot did not have the necessary equipment that would have allowed his passenger to relieve himself in-flight. The pilot decided to stop at E55 (Ocean Ridge, CA) for a pit stop.
A link - “Up the creek without a paddle”
The pilot did not have an A/FD on board that could have supplied him with useful information. Up until this flight he claims had always carried an airport directory and other manuals. He had never had to reference them on a trip before and thought he was “just lugging around extra weight.” In a move to pare down the items in his flight bag, he elected to take only documentation for his destination and planned alternate. Thus when he headed into E55 he had to rely solely on the sectional chart and what he could see visually when he flew over the field. He believed that was enough information to get him on the ground safely. He did land safely.
A link – Forgetting those boring federal aviation regulations
Items that were relevant to this pilot were items the FARS very clearly require. He needed to calculate his take-off distance and he needed to understand how runway slope would factor into his take-off performance, but he did not.
Let us briefly review an edited section of the regs:
A link – Taking advice from other without backing it up.
After the pilot landed he spoke with the airport manager who told him that people preferred to take off on RWY 13 because of the downward slope of the terrain at the departure end of the runway. This guy was the airport manager - he was familiar with the field, so the pilot took his recommendation.
A link - Lack of take-off planning
If the pilot had had and then read the A/DF he would have known that Runway 31 was the FAA recommended calm wind runway. He would also have noted the runway pavement condition. Also the mention of tree obstructions may have prompted him consider the obstructions as a factor in his take-off.
Per the AFD here are some notes:
A link – Runway behind
When the pilot took off he did not use the displaced threshold, thus leaving 400’ of useable surface behind him.
The pilot stated, “If I had used RWY 31, I would have had easy access to the full length of the runway as the taxiway ended a couple of hundred feet behind the displace threshold. The taxiway for RWY 13 put us on the runway at the threshold”
He further stated, “The displaced threshold on RWY 13 that I could have used for my takeoff roll, would have required that I back taxi and make a tight 180 turn on a narrow runway. I made the decision not to use the displaced runway because of the maneuver and the thought that I could get a wheel in the ditch or gravel and damage the plane or prop which in hindsight was a very poor decision considering the outcome.”
“I believe most critical to the cause of the accident, was my decision not to perform a short field takeoff from this field. The temperature was around the low 80s, the field elevation is almost 1000 ft and the runway pavement is rough. Using the runway length listed on the sectional chart, I noted that the runway had similar dimensions to the runway at PAO and SQL where I had successfully made numerous takeoffs. But the runway lengths are the only similarities and I did not consider that my takeoff roll would be extended by the temp, altitude and surface conditions that day. Doing a short field takeoff, the gear would have been off of the rough surface and I would have gotten to the airspeed required for takeoff. Instead, the plane took longer than I expected to reach rotate speed and upon lift off I had immediately gotten a stall warning.”
A link – Comparing apples to oranges and ending up complacent
Since the runway length was similar to KPAO he thought it would be fine. KPAO often has a headwind and is not surrounded by obstructions.
A link - Unfulfilled expectations and unfamiliar visual cues
After adding full power the pilot stated that it took him longer than normal to reach 55 kts, his rotation speed. At 55 kts he rotated and the stall warning sounded. He saw the trees up ahead and he thought he might not clear them so he aborted the take-off and landed. He landed on the runway at the point where it started to slope downward. The pilot was unable to stop the airplane before it went off the end of the runway and slide down a 100 foot hill. The left wing hit a tree and pivoted the airplane 90°. The pilot and passenger were uninjured. The pilot’s door was jammed closed; both occupants had to egress via the passenger door. The airplane had significant structural damage and was totaled.
In the end the pilot said that had he referenced the A/DF, he believes he would have made a different decision regarding which runway to depart on. It is highly possible had the pilot continued his take-off he would had been just fine, but the terrain and trees in the environment spooked him and he thought he would not clear the trees. Of course this is speculation.
To be sure we will all have to deal with the unexpected, we can’t escape that. What are some strategies you can use to stay safe and make good decisions when the unexpected happens?
A good place to start is with a CFI doing some recurrent training. Why wait for that biannual flight review; why not do an annual review? Plan a cross country flight and have your CFI change plans mid flight, forcing you to divert and land at an airport you hadn’t planned for. The CFI can walk through everything with you, pointing out good decisions and pitfalls.
You can also sign up at www.faasafety.gov and take their safety courses. You can also take AOPA’s online courses.
Review the regulations and to the best of your abilities follow them – remember the rules are usually right.
Review the FAAs DECIDE model and the hazardous attitudes and the antidotes.
Do know that we are all susceptible to airplane accidents - from the novice pilot to the veteran 20,000+ hour pilot. I don’t know how many links a pilot needs to string together before he has an accident; I suppose it varies. Remember, if you can detect a link in a possible accident chain and slow yourself down long enough to consider the implications, use the FAAs DECIDE model then act accordingly you might avoid trouble.
Clear skies and smooth tailwinds!
Have fun and DECIDE often and as Nick Ulman says, “fly more!”
AS THE WRENCH TURNS by your friendly maintenance department, maintenance@wvfc.org
I would like to congratulate all of the members as it seems that the articles we have been writing have had a positive effect on the aircraft and their down time. We have seen a significant drop in the dead battery issues and the resulting missed flights. It helps a great deal when members minimize the amount of time electrical equipment is left on during the pre-flight. Also minimizing the use of non-essential systems during the flight helps prolong all of those systems not being used. In this economy, every dollar we can save in maintenance expenses will help in keeping the costs down. Lord knows with the price of everything else going up so rapidly every little step we take will make a big difference.
We also hope that people are using the MX status board and the squawk inquiry capabilities of that screen. Hopefully, this is reducing the concerns about knowing whether or not a plane has a squawk and verifying if all of the squawks are in order prior to renting, or showing up for the aircraft. If you have not used this screen please go to the bottom of most pages of the website and you will see a URL on the bottom of the page, mx status board. Clicking this URL takes you to the Maintenance status board, and the display page for all of the important MX information on our fleet aircraft.
Please let us know if there is any way we can help provide better services to the membership. E mail west valley maintenance at maintenance@wvfc.org.
On a final note, we continue to see a high number of false squawks on the aircraft. Please be sure to do your diligence to assure that system was pre-flighted and is being used correctly prior to squawk. False squawks both clog up the system and keep us from handling the more urgent issues; they also cost the club and you a lot of extra money every month.
Lets get out and enjoy the Spring flying.

Jets are Different by Dave Fry, Aviation Safety Counselor
Five years ago I got my first jet type rating. Eight months ago I got my second, and in the past eight months my total jet hours have gone from 33 to 180. And I’ve just begun to appreciate how and why jets are different from propeller-driven planes.
There are two major areas of differences: First, performance/technique, and second, procedures.
In the performance/technique area, some of the differences are pretty obvious: speed, fuel burn, operating altitudes, and in some cases weight and load-carrying ability. However, the implications of those differences aren’t as obvious.
For example, the speed differences show up in a couple of interesting places. Your pattern needs to be significantly larger to account for the turn radius. Less obvious, but equally important is the length of TIME it takes to turn. At the less-than-10,000-feet speed limit of 250 Knots, a steep 360 takes so long (and so many counties) that you can forget what you’re trying to do. Perhaps the best way to get at the difference it to look at the rollout numbers; in most of our club planes, you start a roll out from a steep turn about 20 to 25 degrees before the desired heading. In the jets, you use a ten degree lead, and still don’t roll out any faster than we normally do in a club plane. Another speed-related point to consider is what happens at higher speeds when the pitch changes just a bit. A pitch change that results in a 100 FPM climb or descent at 120 Knots gives 375 FPM at 450 Knots. And the biggest difference is how far ahead of the plane you need to be. It’s same as any other plane in terms of functions to be performed, but because the functions are more complex, and take longer, it means that you need to be farther ahead in terms of time, and MUCH farther in terms of distance.
When you pull the power in a propeller-driven airplane, it starts slowing down, and in the case of planes with large four-bladed props, it’s kind of like dropping anchor. In a jet, you pull the power, then go back to the galley for a cup of coffee while the plane begins to think about slowing down. The same thing applies to power increases – turbines don’t ramp up the way pistons do. This is why you compute a Vref for each approach based upon density altitude and aircraft weight. And why you fly that Vref. At Hayward for example, the runway required is already a significant part of the total available (unlike most club planes even at PAO), but if you add another 1000 feet onto the landing by coming in 10 knots hot, you’re landing at Oakland
Then there’s the momentum/inertia issue. When a couple thousand pounds starts going the wrong way or sinking faster than you want, it’s bad enough, but when somewhere around 10 tons starts heading the wrong way, it takes a LOT to stop it! And the standard 3 degree glide slope at 130 Knots has a much higher sink rate than the standard 65 Knot approach in most of our club planes.
Then when you finally get it onto the ground, you have to go into counter intuitive mode and get the nose wheel down NOW. Because the thrust reversers will cause the plane to pitch nose up and pop you back into the air at a REALLY slow speed. This is Not Good!! So forget the hold the nose-wheel off mentality we emphasize in club planes.
On the good news side, jets typically have amazingly good autopilots and Flight Management Systems, which can take up much of the pilot’s workload – if the pilot plans far enough ahead to allow for the time to set up the FMS. As an example, with enough time, you can program the FMS to fly a non-published hold hands off.
Finally, add the fact that some of the jets have swept wings, resulting in some very interesting characteristics in crosswinds (since the wind flows across the two wings at different angles).
Next time, we’ll talk procedures, and that’s where the real differences are.
