Each four to five minute video focuses on approach, landing, and taxi scenarios at select U. FlyQ EFB 4. Students can complete their interactive ground training at home before their in aircraft or simulator training.
The webinar will cover how to effectively use flight sims at home, as well as what mistakes to avoid. The best advice is always ask lots of questions, review the logbooks carefully, and be certain to have a good pre-purchase inspection by a well qualified maintenance technician.
The problem in the overhauled Cessna engine is the oil pressure drops gradually after a four to five minute run-up. When it comes to radio communication between flying objects, the single most important thing a pilot can do is be on the right frequency.
I provide my own renter's insurance, of course, and split the cost of the annual with Jeff. That allows me access to fly the Cub. When I'm done with a flight, I top up the fuel tank and put it back in the hangar just as I found it. I fully expect ACE to continue engaging, educating and accelerating the next generation of aerospace professionals. In the media business, we call Jeffrey's column "evergreen" content. It is as valuable today as it was when he started in and will remain so far into the future.
If your plane has been sitting this winter, there's a few things you need to do before spring flying season. In more than 60 years there has been no significant change in aviation oils, even with all of the technical advances in lubricants.
As the piston aviation community faces the switch to unleaded fuel, it pays to know the history of avgas. He added that, during departure from the airstrip in England, Arkansas, after they became airborne for about nine seconds, the engine rpm dropped to idle.
The propeller was still rotating, but the engine was not producing power. Subsequently, the plane landed in a cotton field, the nose landing gear sheared off, and the plane came to rest nosed over. The student pilot reported that the airplane had gone through a pre-purchase inspection the previous week, and the airplane had accrued little time since the annual, which was seven months before the accident.
He added that it seemed like the airplane was starved for fuel. Published as an educational tool, it is intended to help pilots learn from the misfortunes of others. General Aviation News reserves the right to delete snarky, offensive or off-topic comments. See our Comment Policy for more details.
Gravity works 24x7x Water in the fuel…. The airspace between the eardrums of the PIC was a contributing factor of why the aircraft did not reach its destination. Took delivery of my Cessna after having it flown to my home airport by the son of the IA who did the preflight and then the annual for me. Distance was about 50 miles. First thing I did was check the tanks, gascolator and belly drain. Collected a full cup from that belly drain.Cessna Level Post a Comment.
Attached to the outboard end of each strut is a die-cast aluminum wheel and disc brake assembly. Steering nose wheel that is linked through the rudder pedals to give ground control. Shock Strut - The shock strut is made of top and bottom machined cylinders that contain a mixture of oil and air. The top and bottom cylinders give changes in the shock-absorb rates.

TTP Cessna Fuel-injected engines have been common in automobiles for years, and are gaining popularity in General Aviation aircraft.
Fuel injection systems have several advantages over carbureted systems. With fuel injection, each cylinder gets an almost identical amount of fuel. This helps each cylinder put out an equal amount of power.
This in turn makes the engine run smoother and more efficiently. In contrast, carbureted systems are prone to have cylinders which run slightly rich or lean in comparison to the rest because of the differing lengths of the intake pipes.
Fuel-injected engines are much easier to start when the engine is cold because each cylinder gets primed with an identical amount of fuel. Fuel injection systems do have a couple of disadvantages when compared to carbureted systems. Fuel-injected engines can be difficult to start when hot. This process can be frustrating for folks unfamiliar with the quirks of fuel-injected engines.
The fuel injection system is also very intolerant of even the slightest piece of dirt or debris in the lines or injectors. Carbureted systems are generally easy to start when the engine is hot. They also, by design, tolerate impurities a little better than fuel injection systems do. Aircraft owners who fly behind fuel-injected engines will likely enjoy many years of reliable and efficient operation.
Most airplanes also have an electric fuel boost pump, which provides fuel pressure for starting and as an emergency backup. The engine-driven fuel pump is designed to provide constant fuel pressure to the inlet of the fuel servo.
The airflow to the intake pipes of the engine cylinders is controlled through the throttle body and butterfly valve in the servo. This butterfly valve is similar to the butterfly valve in a carburetor. The throttle body is made with a venturi inside; again similar to those in a carburetor. However, the venturi in a fuel servo is only there to provide air pressure settings to an inside chamber in the fuel control section of the servo, not to provide nozzle suction for fuel discharge as it does in a carburetor.
Cessna 172s fuel system; reservoir tank connection to main fuel tanks.
The ball valve is regulated by a series of diaphragms and springs. The diaphragms are used to allow the opposing pressures of incoming impact versus venturi air and metered versus unmetered fuel pressure to constantly regulate the amount of fuel sent out to the nozzles.
The shape of the housing creates the venturi for the throttle body. Impact air pressure is ducted through impact tubes from an opening in the front of the throttle body ahead of the venturi to an enclosed chamber on one side of a diaphragm. Air from the low-pressure venturi section of the throttle body is ducted to a chamber on the opposite side of the diaphragm. As airflow increases, venturi pressure drops.
As airflow decreases, venturi pressure rises. The pressure difference between the impact air which stays constant except for atmospheric changes and the venturi air causes the diaphragm between the two chambers to move slightly whenever there is a change in air pressure on one side or the other. The fuel servo ball valve in the fuel regulator is attached to the diaphragm in such a way that it moves toward a more open or closed position as the diaphragm moves in response to air metering force.
Aviation Stack Exchange is a question and answer site for aircraft pilots, mechanics, and enthusiasts. It only takes a minute to sign up. I went for a 1. I was alone. When I left, I had 18 gallons in each tank. When I arrived back, I had 15 gallons in the left tank, and 10 in the right tank.
Consulting your handy POH or one for a N that I Googled up you'll find the fuel system diagram looks like the one below click to enlarge - most high-wing gravity-fed fuel systems are similar. So there are a number of ways you could wind up with uneven fuel burn with this plumbing.
The most common ones are:. Uncoordinated Turns If you're flying lots of left-hand traffic patterns or you're making lots of left turns for some other reason that means your left wing is frequently lower, and gravity favors pulling fuel from the right tank. Note that it doesn't have to be a turn - prolonged slips can also cause uneven fuel flow.
If I had to take a guess, I'd say this is probably your culprit. Were you making a lot of left turns? Pressure The fuel vent tube on the left tank faces into the wind - this pressurizes the left tank first and the right tank through the breather tube connecting the two - it's a little extra encouragement for fuel to leave the tanks and flow into the engine.
In some aircraft this leads to the left tank draining faster because it's at a slightly higher air pressure than the right tank - this can become particularly pronounced if the breather tube between the two tanks is blocked. Pilot Error It's possible to mis-position the fuel selector in such a way that you're getting adequate fuel flow to run the engine, but one tank is more restricted than the other.
This is unlikely if the aircraft is properly maintained the fuel selector should have nice, identifiable detents that it clicks into, letting you know it's in position. For more detail on causes for uneven fuel burn and tips for troubleshooting it with your mechanic check out Cessna Pilot's Association Technote Is uneven fuel burn dangerous?The Cessna Skyhawk is an American four-seat, single-engine, high wingfixed-wing aircraft made by the Cessna Aircraft Company.
Measured by its longevity and popularity, the Cessna is the most successful aircraft in history. Cessna delivered the first production model inand as of [update]the company and its partners had built more than 44, units. The Cessna started life as a tricycle landing gear variant of the taildragger Cessnawith a basic level of standard equipment. In JanuaryCessna flew an improved variant of the Cessnaa Continental OA -powered Cessna C with larger elevators and a more angular tailfin.
Early s were similar in appearance to the s, with the same straight aft fuselage and tall landing gear legs, although the had a straight tailfin while the had a rounded fin and rudder. Inthe A incorporated revised landing gear and the swept-back tailfin, which is still in use today. The final aesthetic development, found in the D and all later models, was a lowered rear deck allowing an aft window.
Cessna advertised this added rear visibility as " Omni-Vision.Navigation Systems
The Cessna may be modified via a wide array of supplemental type certificates STCsincluding increased engine power and higher gross weights. Other modifications include additional fuel tank capacity in the wing tipsadded baggage compartment tanks, added wheel pants to reduce drag, or enhanced landing and takeoff performance and safety with a STOL kit.
A Cessna was used in to set the world record for refueled flight endurance. Citing safety issues, the FAI has since stopped accepting new entries, so the record will stand. They landed back at McCarran Airfield on February 7,after 64 days, 22 hours, 19 minutes and 5 seconds in flight. The flight was part of a fund-raising effort for the Damon Runyon Cancer Fund.
Food and water were transferred by matching speeds with a chase car on a straight stretch of road in the desert and hoisting the supplies aboard with a rope and bucket. Fuel was taken on by hoisting a hose from a fuel truck up to the aircraft, filling an auxiliary belly tank installed for the flight, pumping that fuel into the aircraft's regular tanks and then filling the belly tank again. The drivers steered while a second person matched speeds with the aircraft with his foot on the vehicle's accelerator pedal.
The pilots decided to end the record-setting flight after running the engine 1, hours continuously in addition to several hundred hours already on the engine beforehand, putting it considerably in excess of its normal overhaul intervaldeteriorating the engine's power output to the point at which they were barely able to climb away after refuelling.
The aircraft is on display in the passenger terminal at McCarran International Airport. Photos and details of the record flight can be seen in a small museum on the upper level of the baggage claim area.
Next time I feel in the mood to fly endurance, I'm going to lock myself in our garbage can with the vacuum cleaner running. That is until my psychiatrist opens up for business in the morning. The basic appeared in November as the model and remained in production until replaced by the A in early The model A introduced a swept-back tailfin and rudder, as well as float fittings.
This added optional equipment included full exterior paint to replace the standard partial paint stripes and standard avionics. The model was the C. It brought to the line an optional autopilot and a key starter to replace the previous pull-starter.Cessna Level Fuel System. Cessna R has a wet wing fuel storage system with two integral fuel tanks one in each winga three position selector valvea fuel reservoir tank, an electrically-driven auxiliary fuel pump, a fuel shutoff valve and a fuel strainer.
Components forward of the fuel strainer include the engine-driven fuel pump, the fuel injection servo and the fuel distribution valve. Fuel bays may need to be resealed if a leak has developed, or if the wing has been repaired. These procedures provide instructions for sealing fuel bays, classifying fuel leaks, and testing fuel bays after repair.

By S P Singh - March 27, For this reason, engines should not be rotated until all of the preservative oil is drained away. Use a solvent to remove tape residue. Remove spark plugs or dehydrator plugs. With the magnetos off, rotate the propeller by hand through sufficient rotations to remove excess preservative oil from the cylinders.
Drain the remaining preservative through the sump. Most engines are equipped with a quick-drain oil fitting on one side of the oil sump and a standard AN plug on the other.I remember being told that the airplane was equipped with a 28 volt, direct current, alternator driven electrical system.
It could have been a 1. As with any topic in aviation, you can learn it on the surface, and then learn it to a deeper level, and then keep learning it at seemingly endless levels of understanding. Better get some more. Watts An Amp? Volts and watts and amps. What are they, and what is the difference? The best way to visualize these fundamentals of electricity is to think in terms of water pipes.
Volts voltage are the pressure of the pump moving the water. Amps current are the flow rate of the water, and volts times amps equals the total power of the system, or watts. A common landing light uses 50 watts of power.
So how many amps does that draw? Those are all the same equation, just solving for the different values. You could math this all day to realize that a lower voltage system would have more amps flowing, as would a higher wattage light.
With 28 volts coming from the battery to a 50 watt landing light, the current is 1. By the same math, a 60 watt bulb in a 14 volt system would draw 4. As the engine turns, it drives a belt attached to the alternator. An alternator works by using the rotation of the belt to rotate a magnetic core inside wiring that produces electrical current.
The 28 volt system, then, means that the alternator is producing 28 volts of voltage. Older aircraft systems used a 14 volt alternator with a 12 volt battery. A higher voltage system reduces the current, making the system more efficient, and without needing increased wire size.
Shocking, right? This cutaway shows the belt that connects the rotating engine crankshaft to the alternator. The Hero Of Ignition Then there are magnetos. I still think of the X-Men character every time.
These little guys are what provide the spark to the spark plugs, which ignite the fuel and make the engine run. The fog lifted on that one when I realized that they are basically miniature alternators.
Every time the engine turns, it drives the magnetos to make a spark. With the key in the off position, wires ground both of the magnetos. In the both position, both of the magnetos are active.
Get On The Bus The electrical components in the airplane such as lights, electrically powered instruments, radios, etc are on electrical buses. A bus is just a common wire that runs a series of components. I think of it like a power strip, where several items are plugged into the same strip, or bus.
Some airplanes allow you to isolate a bus either using a bus circuit breaker or a switch, like an avionics master switch with a split rocker two sides for two different buses. Unlike team. A Short On Circuits Most checklists tell you to check that circuit breakers are in, but what would they be doing out? Circuit breakers are basically automatic switches.
Take a circuit breaker with a 5 on it, for example.
