What will happen if you run the aircraft and the fuel tank is dry?
Even when flying solo, running a tank dry can cause unwelcome complications. On an IFR flight plan, for example, a sudden absence of engine power and a restart can quickly put the airplane significantly off an assigned speed, heading, or altitude.
Why does the fuel cap of Cessna 172 is vented?
It is a pressure/vacuum cap. Meaning it will vent each way in or out but under pressure and under vacuum and is only used in a malfunction situation of your main venting system.
Where is fuel tank cap located on the Cessna 172?
The Cessna 172 fuel system has a total capacity of 212 litres (of which 200 litres is useable) and consists of two vented integral fuel tanks, one in each wing. The tank is located in the inboard section of each wing and has two fuel pick-ups, forward and aft.
Where is the fuel vent on a Cessna 172?
On the C-150/152 and the C-172 the fuel vent is located behind the strut under the left wing, this vented the left fuel tank.

How many fuel sumps does a 172 have?
13 fuel sumps
The fuel should be checked for the correct fuel, contaminants, and water via the 13 fuel sumps located on the aircraft (5 each wing, 3 under the belly going to the reservoir tank, selector drain, and strainer).
How do you drain the fuel from a Cessna 172?
You could drain fuel from the tanks through the sumps, generally located under the wings. A tool with a rod would be required to open the valve on the sumps and you could use a tube with a funnel on it to collect the fuel into a container.
What was the cause of the Cessna 172 crash?
When a Cessna 172 made two off-airport landings due to engine roughness and power loss, the NTSB determined the probable cause of the accident was the restricted vented fuel cap and obstructed fuel vent lines, which resulted in a total loss of engine power due to fuel starvation. And the list goes on. Venting—a boring subject, perhaps.
How do you change fuel in a Cessna 172?
But I guess this is okay if it is in the POH. Just switch to one tank, ignore the sputtering, glide for 60 (very long) seconds, then switch to the other tank and hope the vapor has cleared and the engine restarts.
What does one on board mean on a Cessna 172?
“OK city approach, Cessna 1234Echo, seven south-west of three-Oscar-three at seven thousand five hundred, losing engine power, inbound Purcell, one on board.” Let me assure you that even before declaring an emergency, once you say “one on board” you have ATC’s full attention and everyone else on the radio gets really, really quiet.
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.
