What is the fuel range of a Cessna 172?
885 nmi
The model has a top speed of 131 kn (243 km/h) and burns 3 U.S. gallons (11 L; 2.5 imp gal) per hour less fuel than the standard 172. As a result, the model has an 885 nmi (1,639 km) range, an increase of more than 38% over the standard 172.
What is a bank 1 air fuel ratio imbalance?
Air-fuel ratio cylinder imbalance is a condition where the air-fuel ratio in one or more cylinders is different than the other cylinders. When air-fuel ratio cylinder imbalance occurs in one or more cylinders the fuel delivery system is unable to maintain a proper vehicle emission level.
What does code P219B mean?
Bank 2 Air/Fuel Ratio Imbalance
The trouble code P219B can be explained as Bank 2 Air/Fuel Ratio Imbalance. This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model.
What does the fuel system look like on a 172N?
Consulting your handy POH (or one for a 172N 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.
Can a fuel line blockage cause uneven fuel burn?
A partial blockage in either of the tank fuel lines, the fuel selector valve, the vent, or the breather line between the two tanks could theoretically cause uneven fuel burn (the vent/breather blockages being a special case of “pressure” from (2) above).
Can a Cessna fly with 800 pounds on it?
The weight difference will not affect your flight. If one tank is empty and the other nearly full you may bank slightly to that side, but Cessnas can easily handle 800 pounds hanging on the wing strut. Thanks for contributing an answer to Aviation Stack Exchange!
What happens if your left fuel tank is empty?
In an extreme case your right tank may be empty and your left tank may be so low as to unport the fuel pickup tube in a turn, potentially leading to attitude-induced fuel starvation (“The noisy part of the plane gets quiet until you level the wings”). I asked my instructor and this was his answer!
