This means that if you hold the aircraft on either one of those lines and hold the ball in the center it will take two minutes to complete a 360° turn. On the outside of the dial, the 2 markers below the horizontal lines represent a standard rate of turn. The tube with the black dot in the middle represent the balance of the aircraft, during normal flight operations, it is good practice to use the rudder to keep the ball in the center to keep the aircraft well balanced or ‘coordinated’. It is important to remember that this is not a bank indicator and not to use it as such. These systems are modelled fairly accurately in the Asobo Cessna 152, however I won’t be covering CDI procedures in this guide.Ħ : Turn Coordinator – The aircraft on this display shows the rate of turn (rate of change in heading) by banking towards the direction of turn with varying intensity depending on how fast the rate of turn is. This can also be tuned to an ILS (Instrument Landing System) frequency which allows the pilot to follow the glideslope down to the runway when visability is bad. The knob can be used to calibrate the altimeter to the outside atmospheric pressure either in Inches of mercury (Hg) or Millibars (mb) to make sure the instrument reads correctly.ĥ : Course Deviation Indicator (NAV1) – Used for navigation, it can be tuned to receive frequencies from VOR beacons on the ground and direct the aircraft towards it. The service ceiling of the cessna 152 is 14,700 feet so its advised that the aircraft stays below that altitude for good performance. The longer needle represents hundreds of feet and the shorter needle represents thousands of feet. Note that the gyroscope only works when the engine is running.Ĥ : Altimeter – Displays the aircrafts current altitude (height) in feet. As the aircraft rolls the orange arrow will pass through marked lines on the top half of the display, from the middle out, indicating 0, 10, 20, 30, 60 and 90 degrees angle of bank. The orange arrow on top represents the aircraft’s angle of bank relative to the horizon. With blue indicating the sky, brown indicating the ground, and where they meet the horizon. The beginning of the green and white arcs represent the stall speedĢ : Artificial Horizon – A gyroscope that indicates the attitude (relative orientation) of the aircraft. The red line represents the maximum speed before structural faliures are likely to occur. The green arc represents the normal operating speeds of the aircraft, and the yellow arc represents speeds you should only fly with in smooth air. The white arc that goes up to 85 knots represents the flap operating range, you don’t want to exceed the white arc without fully-retracting the flaps first. The main instrument panel of the Cessna 152ġ : Airspeed Indicator – Displays indicated airspeed in knots (KIAS) on the outside of the dial and miles per hour on the inside. This may sound like a lot to learn but if you do a free flight in the simulator you should be able to figure all this out by yourself pretty quickly. These are rudder pedals, they are used to control the rudder of the plane This is a yoke, it is used to control the elevators and ailerons of the plane Covered in depth in the Cockpit Walkthrough section of the guide. Orange | Trim - Used to keep the plane flying level without having to manually change the pitch of the plane. Controlled using the rudder pedals (see below) Pushing your left foot forward will cause the plane to yaw to the left, and vice versa. Red | Rudder - Used to change the yaw of the plane. Pulling the yoke (see below) towards you will raise the nose of the plane and pushing it away from you will lower the nose. There are instructions on how to use these in the Cockpit Walkthrough section of the guide.īlue | Elevators - Used to control the pitch of the plane. Green | Wing Flaps (Flaps) - Used to keep the plane in the air at slower speeds, usually at landing. Moving the yoke (see below) to the left will role the plane to the left and vice versa. Yellow | Ailerons - Used to control the roll of the plane. The movable surfaces of the Cessna 152, shown in the colours: yellow, green, red, blue and orange
