Could this "Wingless Dodo" fly in real life?

There is an old saying "If you put a big enough engine on it, you can make anything fly." The Lockheed Starfighter was a classic example of that. With its short stubby wings it is basically a guided ...

C-152 carb heat on before landing in hot weather?

You should always pull the carb heat when throttling back no matter the conditions for 3 reasons: Ice forms from moisture (duh!), and there's much more moisture in hot tropical air than cold arctic ...

Why does the Cessna 152/172 nose wheel turn only when the aircraft is moving?

Because the nose wheel is only attached to the rudder pedals indirectly, through some springs (or maybe a bungee cord), that transfer the displacement of the pedals into a force that is applied to the ...

C-152 carb heat on before landing in hot weather?

Carb heat use is not related to OAT, it's related to moisture and how it can turn to ice in the carb, causing the engine to stop. Carb ice can form at any outside air temperature, which is why you ...

What determines the best glide speed?

Basically, the faster you go, the more lift and drag a wing will produce. These two values are not proportional, though. When speeding up, the amount of drag produced is higher than the extra amount ...

Should I have carb heat on for landing in a C152?

The approach and landing phase are the times when carburetor icing is MOST likely to occur. Once a carburetor has ice, it may take a period of time for full application of carburetor heat to clear ...

Could this "Wingless Dodo" fly in real life?

The minimum speed of a Cessna 152 is 43 knots while the maximum speed is 110 knots. If the wing area is reduced to one half of its original size, and we accelerate to twice the minimum speed, the ...

C-152 carb heat on before landing in hot weather?

You have mentioned OAT, but remember there are 2 variables for potential icing - the other being Dew Point. You (roughly) 85F OAT could easily fall into Serious Icing at glide power for a wide range ...

What is the maximum crosswind limit for a C150/2 aircraft?

Section 4 of the C152 POH lists the demonstrated crosswind component as 12KIAS. The 150 had a few variants so finding a published number is a bit more tricky. The Aerobat's are sometimes listed as ...

Why is the magneto drop check done at 1700 RPM?

It's not a magic number and, truth be told, the runup mag check is not a very good check of ignition system health. It's more of a "good'nuf" holdover from an era before multiprobe engine monitors. ...

What flaps position should be used for taking off from a wet runway?

The POH for a 152 lists the flap settings for takeoff as between 0° and 10°. It makes no specific mention of take off from a wet runway, however you could follow the same procedures for a soft/...

Can I do an alternator check at idle in a C152?

The problem is the light might come on on its own at idle, which is normal. The warning light comes on when the system voltage is below 12.5 volts on a 14 volt system, and 25 volts on a 28 volt system....

Why does the Cessna 152/172 nose wheel turn only when the aircraft is moving?

I'm not a pilot, nor have I ever been in a C172, but I'm going to go out on a limb here and answer from a logical physics point of view and say the answer is that it's because the nose-wheel steering ...

What is that pitot-like device under the left wing of the Cessna 152?

It's the fuel tank vent. It prevents forming a vacuum in the gas tank as it's drained, which would prevent further fuel flow to the engine.

Nose gear weights

In a tricycle gear aircraft, the nosewheel supports little of the weight. The center of gravity of the aircraft is only slightly in front of the main gear, and so the nose gear only has to hold the ...

Could this "Wingless Dodo" fly in real life?

This depends on if you modify the wing or not. If you are asking the question: If you chop 3/4 of each wing off will a plane still fly? The answer is more or less no. The wings simply won’t ...

Does full nose up trim yield best glide in Cessna 172/152 for a given load?

That ground instructor is giving you bad information. You can not make a blanket statement like "full nose up trim" and expect it to be valid for any and all situations. You are correct that the best ...

What determines the best glide speed?

The most important factors for the best glide speed are the aircraft's wing loading, the air density, the wing's aspect ratio, and the aerodynamic quality of the aircraft. The aircraft must create ...

Why is the landing distance increased on grass runways?

The long and short of it is that wheels are designed for smooth tarmac. While grass increases friction on the wheels on takeoff (making the aircraft work harder to get up to speed), it also reduces ...

Is it feasible to replace a C152's engine with multiple small turbine engines?

Have a look at the Cri-Cri propeller and jet versions. Yes, jets can be mounted near the nose, but the plane must still balance at within its specified CG range. This is why removing the engine in ...
