List the three LSA bands in Normal Mode (NM) and what they indicate:

Vss - Top of the white tape
-Low-Speed Protection function
Vaoa - Top of the Amber Tape
AOA Limiter Function Activation
Vlim - Top of the Red Tape
The Speed Associated with the Maximum Allowable AOA Airspeed

(AOM 9-08-30)

**Do the Vss and Vaoa/lim indications behave the same in turns and other maneuvers? Why or why not?

No, because *Vss is defined in terms of Speed and **Vaoa/Vlim **are defined in terms of AOA (AOM 9-08-30)

Do Vaoa and Vlim increase with Load factor?

No
(AOM 9-08-30)

Is the **AOA Limiter** function operational in **Direct Mode (DM)**?

**No** (AOM 9-08-30)

List the (2) **LSA bands** in **Direct Mode (DM)** and what they represent:

1. **Vms** Top of the **Amber Tape** 2. **Vsa** Top of the **Red Tape**, Indicates the Airspeed at Which the **STALL** aural alert is triggered (AOM 9-08-30)

Are the **Pitch Limit Indicators** (Plls) displayed in **Direct Mode (DM)**?

**No** (AOM 9-08-30)

What color does the **Pitch Limit Indicator** become if the airspeed drops below **Vaoa** in Normal Mode (NM)? How about **Vlim**?

Airspeed < **Vaoa Amber**; Airspeed < **Vlim Red** (AOM 9-08-30)

How many Flight Control Computers **(FCCs)** are sufficient to provide **Normal Mode (NM)** functionality?

**One** (AOM 9-08-40)

What is the purpose of the **Black Airplane Battery**?

To withstand operation of a minimum of **15 minutes** in order for the flight crew to **Recover** the **Proper Airplane Electrical System Operation**. (AOM 9-08-40)

How long does each PBIT test of the FCS take?

**Less** than **One Minute** (AOM 9-08-40)

If the PBIT conditions are not satisfied, up to how many PBIT operation attempts can the FCS automatically perform?

Up to **Three** (AOM 9-08-40)

During a PBIT operation, which CAS message is displayed?

• The **FLTCTRL TEST IN PROG** CAS message (AOM 9-08-40)

When is the **De-Rotation** Control Law Active?

When the airplane **Touches Down** (AOM 9-08-50)

What does the **De-rotation** Control Law provide?

A **Smooth Nose-Down Movement** by Commanding the **Elevator** to a **Nose-Down** pitch of **2° per second** (AOM 9-08-50)

What does the **Neutral Spiral Stability** Control Law provide?

It automatically **Trims the Elevator** when the Sidestick Controller is Set back to the **Neutral** position to *Maintain* **Level Flight** during turns **up to 33°** of bank angle (AOM 9-08-50)

If the pilot commands a turn with a Bank Angle of **greater than 33°**, what do they need to do in order to **maintain level flight in that turn**?

**Maintain** the Desired Sidestick **Lateral Deflection** and Move the **Sidestick Controller Aft** (AOM 9-08-50)

List the **(4)** conditions that will cause the **Speed Brakes** to Automatically **Stow**:

If the Speed Brakes are Automatically Stowed, What Indication will the pilots have and how can the speed brakes be reactivated?

• The cyan **SPDBRK LEVER DISAG** CAS message is displayed and the **SPEED BRAKE LEVER** must be set back to **STOW** (AOM 9-08-50)

Define a **Flight Control Normal Mode (NM) Misbehavior**:

Any **Airplane Behavior** that the flight crew realizes it is **Behaving Unexpectedly**, **Not Responding** adequately to the commands, or is presenting a **Lack of Response** (AOM 9-08-50)
