How much fuel is considered to be part of the empty weight of an aircraft?
Unless the specific weight for an item is known, the standard weights used in aircraft weight and balance are as follows: Aviation gasoline 6 lb/gal.
Turbine fuel 6.7 lb/gal..
Why are aircraft engines shut off by shutting off the fuel rather than the ignition?
Combustion in a gasoline internal combustion engine for most aircraft, requires four things: fuel, oxygen, compression and ignition. … So shutting off the fuel is one way to prevent accidental “start” if even for one stroke. Oxygen is ubiquitous and is not practical to eliminate from the engine environment.
What is the maximum gross weight of an airplane in the normal category?
The total loaded weight of 3,320 pounds does not exceed the maximum gross weight of 3,400 pounds, and the CG of 84.8 is within the 78–86 inch range; therefore, the aircraft is loaded within limits.
What is the minimum reserve fuel required for day VFR operations?
One hour of fuel reserve on IFR flights (airplane and helicopter) One hour of fuel reserve on airplane VFR flights regardless of day/night conditions. 30 minutes of fuel reserve on helicopter VFR flights.
Why is it necessary to drain fuel from the fuel sumps?
Aircraft fuel tanks are constructed with sumps to trap water. Since it is practically impossible to drain all water from the tanks through the fuel lines, the fuel tank sumps should be regularly drained in order to remove all water from the system.
What is final reserve fuel?
Final reserve fuel is the minimum fuel required to fly for 45 minutes at 1,500 feet above the alternate aerodrome or, if an alternate is not required, at the destination aerodrome at holding speed in ISA conditions.
Why are aircraft engines so expensive?
Gets sued for millions. So, airplane and engine manufacturers inflate prices to cover legal fees or insurance liability costs. As an example, the alternator used on many Lycoming engines is the same one used on Ford engines. The Ford version is around $150.
What is the most reliable aircraft engine?
In general aviation terms, the 400 hp Lycoming is the peak of the pyramid with a flat engine. (There are a number of round engines with seven or more cylinders that produce more horse- power, but none remain in production.
How long does Plane fuel last?
I have tested several high lead level avgas samples and observed the loss of several numbers after two to three years. However, most 100LL fuels are blended to above the standard. The ones I have tested that have been stored up to five years still met the 100/130 standards.
Who is responsible for the correct weight and balance of every flight?
1-1] The pilot in command of the aircraft has the responsibility on every flight to know the maximum allowable weight of the aircraft and its CG limits. This allows the pilot to determine on the preflight inspection that the aircraft is loaded in such a way that the CG is within the allowable limits.
How much does an aircraft engine overhaul cost?
It is recommended that most piston aircraft engines be rebuilt every 1,800 to 2,000 or so hours. This TBO time is set by the engine manufacture. Overhaul costs can easily run around $18,000 so an aircraft with a run-out engine will cost quite a bit less than one with a newly rebuilt engine.
What causes an engine to keep running after turned off?
Running-on is when the engine continues to turn after you’ve switched off the ignition because the fuel /air mixture is being ignited by a hot-spot in the combustion chamber .
What do you do when altimeter settings are not available?
When a local altimeter setting is not available the altimeter should be set to the field elevation for the departure area. 4. Answer C is correct. When operating an aircraft between sunset and sunrise (with the exception of Alaska), the aircraft position lights must be on.
Will the engine still run if the master switch is turned off Cessna 172?
Will the engine still run if the master switch is turned off? Yes. The engine operates on fuel flow and magnetos. Magnetos produce the spark for ignition as long as the engine is rotating.
Can I rebuild my own aircraft engine?
Only the manufacturer, or a facility it approves, can rebuild an engine. … In most cases, an FAA-certificated airframe and powerplant (A) technician can legally overhaul your piston aircraft engine and return it to service, providing it doesn’t need any major repairs.
What would cause a car to not turn off?
If the engine continues to run just as before you turned it off – as if you hadn’t turned it off at all – your ignition and fuel system are not shutting down. In that case, your car has an electrical problem that needs to be addressed. Either your ignition switch element or a power relay needs to be replaced.
How do planes fly with so much weight?
A plane’s engines are designed to move it forward at high speed. That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane’s weight and holds it in the sky. … The wings force the air downward and that pushes the plane upward.
