Learn About an Aircraft, Part 3

  • Straight and Level Cruise:
Start by setting the RPM to a cruise setting of 2200 RPM, using the throttle. This should give us a cruise speed of about 108 Knots.
Use the yoke to maintain level flight by keeping the small aircraft symbol level and exactly on the "Artificial Horizon" line of the six pack . Keep scanning the rest of the six pack to help maintain level flight. Scanning the six pack will show if you are going straight or turning, climbing or descending or if the airspeed or altitude starts to change. Always use small corrections to the aircraft's attitudes and wait to see the response.

  • Climbing Phase:
We will climb by increasing the throttle to full throttle. Now you can pull back on the yoke to raise the aircraft nose to about ten degrees above the horizon. Now set your climb speed (using the yoke), by changing this 10 degree climb, until you have an airspeed of about 80 knots. meanwhile continuing to scan the six pack at all times and make sure that nothing is changing that you don't want to change. Scanning the six pack will show if you are going straight or turning. or if the airspeed starts to change.
This Aircraft will stall (in a turn) at approximately 53 knots (no flaps) so keep your turns shallow and avoid any speed below 75 knots to allow yourself a margin of safety. Always use small corrections to the aircraft's attitudes and stay well out of any limit zones that are indicated on the instruments.

  • Descent Phase:
A descent to a lower altitude is done by reducing the throttle to an engine speed of about 1500 RPM while setting the air/fuel mixture at full rich (red knob fully inward). If you intend to be descending a long time at low engine power, then you should use carburetor heat to prevent icing. At reduced RPM, the engine will not be producing as much heat so we may have to put on the carburetor heat, or you can occasionally increase the engine speed for a minute to gain some heat and clear the engine.

How do I troubleshoot the cruise control of a 2003 Alero?


It's probably a problem with cruise control module , located under the hood in engine compartment . Or a bad connection somewhere . Do you know how to do electrical testing ? Is the air bag light lit on the instrument cluster ?

Could have DTC'S - diagnostic trouble code's stored .
DTC P1554
The powertrain control module (PCM) inhibits cruise control operation when certain conditions are not appropriate for cruise control operation. The PCM removes the ground from the cruise control inhibit signal circuit in order to disengage cruise control operation.
DTC P1585
Output driver modules (ODMs) are used by the powertrain control module (PCM) in order to turn on many of the current driven devices that are needed to control various engine and transaxle functions. DTC P1558 set indicates that an improper voltage level has been detected on the signal circuit which controls the cruise control inhibit circuit.
Action Taken When the DTC Sets
• The PCM will not illuminate the malfunction indicator lamp (MIL).
• The PCM will store the conditions present when the DTC set as Failure Records data only.

Cruise control is a speed control system that maintains a desired vehicle speed under normal driving conditions. However, steep grades may cause variations in the selected speeds. The electronic cruise control system has the capability to CRUISE, COAST, RESUME SPEED, ACCELERATE, and TAP-UP or TAP-DOWN.
The main parts of the cruise control system are:
• The cruise control module assembly
• The function control switches
• The cruise control release switch
• The clutch pedal position switch (CPP), if equipped
• The stop lamp switch assembly
• The vehicle speed sensor
The cruise control system uses the cruise control module assembly to maintain the desired vehicle cruise speed and operation. The cruise control module assembly has an electronic controller and an electric stepper motor to vary the throttle in each different cruise control mode. The electric controller monitors vehicle speed and operates the electric stepper motor. The stepper motor operates in response to the electronic controller, to maintain the desired cruise speed. The electric stepper motor moves a strap that is attached to the cruise control cable which moves the throttle linkage. The cruise control module assembly contains a low speed limit which will prevent system engagement below a minimum speed of 40 km/h (25 mph). The module assembly is not serviceable.

cruise control went out on my 2005 ford taurus and my accelerator gets stuck at times. Should I replace the cruise control?


This is a dangerous defect. What you want to do is isolate the Cruise cable from the Throttle mechanism. Then get the Cruise cable away from the Throttle so it can not jam the Throttle accidentally.

With the engine OFF use your hand and move the remaining Throttle mechanism and feel for sticking or roughness in the control. If you feel binding, start removing the connection of the Throttle cable and work your way through all the moving parts like a Butterfly flap on the Airhorn, the TPS (throttle position sensor) and so on until you find out what is rubbing.

It is possible that the Cruise was disengaging because the Throttle parts were binding. If disconnecting the Cruise eliminates the sticking throttle, then all the problems came from the Cruise control cable or the Cruise Box. Once you have made a thorough check of the Throttle you can blame the Cruise for your problems and replace the parts.

check for a vaccuum leak this is where i would start if it rolled into my shop. possibly a PCV valve sticking or a hole in the hose, this hose should run from the valve cover, or crank case and then to the intake, or carb.
