Cessna 152 Control Panel and Cockpit

Cessna 152 | Flying the Desert

Confused about the Cockpit ?

Here's an explanation about all the dials, controls and buttons
you see above, in this typical Cessna 152 Control Panel layout.

Turn Coordinator 1 Tells you how far you have turned horizontally.
Airspeed Indicator 2 Tells you how fast you are flying relative to the air.
Suction Gauge 3 Indicates the amount of pressure available to power the instruments.
Directional Indicator 4 Like a compass, this you where you are headed but is much more stable.
Attitude Indicator 5 A.k.a. Artificial Horizon. This one is handy if you are flying in cloud and you're not sure if the nose of the plane is pointing into the ground or up into the sky.
Registration Number 6 The name of your plane, to be used when contacting Air Traffic Control.
Vertical Speed Indicator 7 Tells whether you are climbing or descending, and at what speed.
Altimeter 8 This tells you your altitude
Clock 9 This tells the time to the minute, in Greenwich Mean Time.
ILS Glide Slope Indicator 10 Some planes have this to help them land in cloudy conditions when electronic assistance is required.
Transponder 11 An electronic identifier that tells the guys on the ground looking at their radar exactly which spot on their screen is you.
ADF Radio 12 A navigational aid that gives you the angle between your plane, North and a radio station. This box enables you to find the radio station you want.
Marker Beacon 13 Used to tell people landing in cloudy conditions that they are approaching the runway.
Radio 14 This box controls who you talk to when speaking in the microphone.
Audio Control Panel 15 This box controls outward messages on the microphones. It selects the receiving stations and headsets and also controls the volume.
Flight Hour Recorder 16 This one tells you how much you owe the owner of the plane.
Tachometer 17 Same thing, but this one records the time you use the plane from the moment you start the engine till you turn it off.
EGT 18 Some planes have this to help smart pilots adjust the air/fuel mix for optimum performance as they climb in thin air.
ADF Bearing Indicator 19 This gives your bearings according to #12: the ADF Radio. This box is old, tricky and unreliable but is still widely used.
Accelerometer 20 In case you thought you were in the Navy, you can tell from this dial how many G's you and the plane are experiencing. Too high, too bad.
Low-VoltageWarning Light 21 If the engine or the battery is not generating enough electricity, this one blinks.
Ammeter 22 This one measures the current in the electric circuitry, but is it coming from the engine or the battery?
Map Compartment 23 Where you put everything that might fly about in rough weather.
Cabin Heat Control 24 If you're cold, the engine will lend you some hot air.
Cabin Air Control 25 If you are talking too much or there's a bit of heavy breathing going on and you're fogging up the cabin, you can use this control to get some fresh air - the sort you get at 6000 feet.
Circuit Breakers 26 You should check these - frequently - at the beginning of the flight to see if your smart boxes, at least, are correctly fed.
Wing Flaps Controls and Indicators 27 These control the electric flaps. They're clever devices that increase the size and angle of your wings when necessary.
Mixture Control 28 Use this to adjust the fuel/air mixture to provide the engine with optimal fuel.
Throttle 29 This one is to go forward.
Microphone 30 No comment.
Carburetor Heat Control 31 This is a very important and rather complicated control. If you are flying in damp air, and if the air temperature is within a certain range, the carburetor (that piece of the engine that brings in the air needed to ignite the fuel) could FREEZE, and then you could crash and die. So in cold or wet conditions, you always have the option of warming the carburetor, however, this means you lose power and expose the engine to some additional troubles.
Elevator Trim Control Wheel 32 This helps you to adjust the elevator (the thing that makes you go up and down) so that you can leave the control wheel alone instead of pulling on it like crazy.
Electrical Switches 33 These turn various lights on and off.
Oil Pressure Gauge 34 Like the one in you car.
Oil Temperature Gauge 35 Same thing.
Instrument Panel Lights 36 If you are flying at night, you need to see the control panel but you don't want it to dazzle you. This knob adjusts the light.
Fuel Quantity Indicators 37 VERY important, these tell you very APPROXIMATELY how much fuel you still have, or how much was left by the last guy who flew the airplane.
Ignition Switch 38 To start the engine, turn the key.
Master Switch 39 This turns on all the electrical devices in the airplane.
Primer 40 Use this to inject some fuel into the engine before starting it.
Parking Brakes Control 41 This brakes the wheels while the plane is on the ground. Note that it can be deadly if you forget to release the brakes before landing the plane. Then you can blow the main tires on landing, leaving you to proceed on down the runway as best you can.
