Pilot ground study

Try the Caravan EX pilot samples.

Explore fuel-system relationships and a supplied indication record, or enter your own answer in a fresh paper loading calculation. These two pilot samples are separate from the maintenance samples below and do not award course completion.

Interactive Fusion sample

Explore the controls.
Read the evidence.

Learn what four Fusion controls do. Then assess a red VOR 1 flag by comparing the cursor control panel, the PFD's VOR/LOC 1 selection and electrical power to the NAV 1 receiver.

01 / Control purpose

AFDAdaptive Flight Display

The adaptive flight display combines a touchscreen with avionics computing. The left and right primary flight displays (PFDs) show attitude, heading, altitude and airspeed. The center multifunction display (MFD) shows engine indications, crew alerts and selected pages such as maps, radio tuning and maintenance information.

Try it in the sketch

Select a format for the center MFD.

What changes
Selecting a format changes the content shown in the center display sketch.
Keep separate
Opening a map page shows that the page can be displayed. It does not test the GPS position or other navigation information shown on that page.

02 / Assess the VOR 1 flag

Did CCP 1 fail to select VOR/LOC 1?

  3. Reconcile

A technician reports a red VOR 1 flag after using cursor control panel 1 (CCP 1) to select VOR/LOC 1 on primary flight display 1 (PFD 1). The report blames CCP 1. Check the NAV 1 receiver's power condition and both PFD indications before accepting that diagnosis.

The cyan VOR/LOC 1 selection and red VOR 1 flag are observed with the NAV 1 circuit breaker open. The receiver is unpowered in this fictional ground-test exercise.

Next observation is concealedPredict before revealing the result.

The next supplied observation closes the NAV 1 circuit breaker to power the receiver. VOR/LOC 1 remains selected on PFD 1.

The open NAV 1 circuit breaker is a supplied condition of this fictional ground-test exercise. This simplified explorer explains the controls and the displayed test results. Current aircraft-effective instructions govern actual maintenance.

Interactive air-data sample

Follow ALT from the ADC to the PFD.

The air data computer (ADC) uses pitot pressure, static pressure and temperature inputs to compute air data for the adaptive flight displays (AFDs) and integrated avionics processor system (IAPS). The attitude heading reference system (AHRS) supplies attitude and heading through a different set of components. A lit primary flight display (PFD) can still show invalid altitude data.

Pitot/static and temperature inputsADC-3000 No. 1 / No. 2AFDs and IAPS input/output concentrators

Both PFDs remain lit and responsive. A technician reports ALT failures with ADS1 selected. Compare all three sourcing states before choosing the next investigation.

PFD1 AFD No. 1

Selected altitude data: ADS1

ADC-3000 No. 1

Display power and unrelated functions remain available.

PFD2 AFD No. 3

Selected altitude data: ADS2

Your recorded comparisons

  • Normal: PFD1 uses ADS1; PFD2 uses ADS2PFD1: ALT fail · PFD2: ALT valid

The actual Reversionary Control Panel (RCP) uses an ADS SOURCE up/down switch. This sample selects its documented sourcing results. The menu choices are not three physical switch detents. Automatic air-data reversion is inhibited on the ground.

Compare normal, common ADS1 and common ADS2 sourcing to unlock the question. 1 of 3 states recorded.

Textron 434-590169-0009, saved B10 study tasks: 34-10-00 Description and Operation, B0; 34-10-01 Adjustment/Test, B9, section 3 introduction and A–B; 31-60-00 Description and Operation, B3, section 1; 34-20-00 Description and Operation, B0. These support the system roles, display identities and sourcing states. The faults and supplied observations are original training examples.

This ground comparison does not apply pressure, perform aircraft maintenance or reproduce flight behavior. Current aircraft-effective instructions govern actual work. The public sample does not record course completion.
