Difference Inner Loop and OUTER Loop => Autopilot 

A closed loop control system in which a samll power input controls a much larger power output in a xtrictly proportionate manner is known as : 

An inner loop control system in one in which: 

In an autopilot system:

What is the most basic functions of an autopilot 

The functions of an autopilot (basic mode) sonsist of:

An automatic pilot is a system which can senure the functions of: 

The vetical flight path modes of an autopilot sytem are:

1) Pitch attitude hold

2) altitude hold

3) Track hold

4 Glide slope interceot and track

The computer of the autopilot  system used, among othersm input signals from the 

1) attitude reference system 

2) mode annunciator panel 

3) ADC Air data computer

4) Mode control panel 

When engaged in the pitch hold mode, teh autopilot uses data ussued by the ;

When disengaging the autopilot, the function providing a smooth handover is the:

The autopilot is engaged with no modes selected. What is the autopilot providing 

The command functions of an autopilot include, among others, the holding of: 

1) vertical speed

2) altitude

3) attitude

4) bank

5) Heading 

an autopilot comprises in addition to the mode display devices, the following fundametal elements:

1) Airflow valve

2) sensors 

3) Comparators

4) Computers

5) Amplifier

6)Servo-actuators 

The computer of the autopilot system uses, among others, the following parameters:

In an autopilot system the basic stabilization modes are:

1) altitude hold

2) Pitch attitude hold

3) Roll attitude hold

4) IAS hold 

GO AROUND mode activate?

CWS: Where the pilot has the ability to make inputs to the:

Autopilot is on. Barometric pressure is decreased, what happens?

The vertical flight path modes of an autopilot system are:

1) Pitch attitude hold

2) Altitude hold

3) Track hold

4) Glide slope intercept and track 

An autopilot capable of holding at least altitude and heading is compulsory: 

Among the following functions of an autopilot, those related to the airplane guidance are:

1) Pitch attitude holding 

2) horizontal wing holding 

3) indicated airspeed or Mach number holding 

4) altitude holding

4) VOR axis holding

6) yaw damping 

Inner loop => stablization on one axis ==> Wenn alle 3 => Welche 

Th epurpose of the autopilot Control Wheel Steering mode is:

When being engaged and without selecting a particular mode, an automatic pilot enables:

teh control law of a transport airplane autopilot control may be defined as the relationship between the:

The interception of a localizer beam by the autopilot takes place:

In an autopilot slaved powered control circuit, teh system which ensures synchronisation

The components of an autopilot system are the:

1) Actuators 

2) Mode control panel

3) EGIS control panel

4) Mode annunciator panel 

the guidanve functions of a autopilot consist in:

When egaged in the FMS lateral navigation mode (LNAV) teh autopilot uses:

In an auto-pilot system, aircraft flight path modes include which of teh follwoing:

1) Pitch attitude holding 

2) Horizontal wing holding 

3) VOR axis holding 

4) Inertial heading holding 

5) IAS and Mach hold 

6) YAW damper 

The autosynchronisation feature of an autopilot system does which of the following?

1) Prevents snatching on engagement 

2) Prevents snatching on disengagement

3) Cancels rudder input 

4) Works in climb, cruise and descent 

For capturing and keeping a preselected magnetic heading, the flight director computer takes into account:

1) Track deviation 

2) rate of rack closure

3) rate of change of track closure

4) wind velocity given by the INS 

The essential components if a FD (flight directors) are:

1) a computer

2) an automatic pilot

3) an autothrottle

4) command bars

The flight director computer continously:

The purpose of a fligh director is to:

An aircraft flies steadly on a heading 270. Fhe FD is engaged in the HDG, heading 270 selected. If a new HDG 360 is selected, teh vertical trend bar:

During a final approach, the FD is engaged in the G/S mode (holding of ILS Glide Slope). If the horizontal command bar is deviating upward, it means that :

the output data of the flight director computer are
