Instrumentation 2

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

Concerning the command bars of a FD: => How to remove the command bars?

The purpose of the FD system is /are:

1) give the position of the aircraft according to radioelectric axis

2) give the position of the aircraft to waypoint 

3) to aid the pilot when fyling manually 

Command bars of the flight director may be present on the :

1) HSI

2) CDU

3) ADI 

The flight director is engaged in the heading select mode (HDG SEL) with heading 180 selected. When the actual heading of your aircraft is 160, the vertical bar of the FD;

The flight director (FD) provides information for the pilot:

During a final approach, teh flight director system is negaged in the LOC mode (holding of localizer axis), the position of the vertical command bar indicates: 

During a final approach, teh flight director system is engaged in the LOC mode (holding of localizer axis). The position of the horizontal command bar indicates: 

1) the position of the aircraft relative to the ILS glide slope 

2) the correction on the pitch to be applied to join and follow the ILS glide slope 

3) the instantaneous deviation between the aircraft position and the ILS glide slope 

During a final approach, the FD system is engaged in the LOC mode (localizer axis holding) The position of the vertical command bar indicates: 

1) The position of the aircraft relative to the localizer axis

2) the roll attitude of teh aircraft

3) the correction on the bank to be applied to join and follows the localzer axis 

The red pointer which is normally on the red line in the EGT indicators 

Electrical requirements for an alumel/chromel indicating system are:

C ind Fahreneinheit?

The main advantage of a ratiometer-type temperature indicator is that it:

A millivoltmener measuring the electromotive force between the hoz junction and the cold junction of a thermocouple can be directly graduated in temperature values provided that the temperature of the: 

The measurment of the turbine tempaerature or of the EGT is carried out at the: 

Iron and brass are commonly used in bimetallic therometers. because 

Given 

E = electromotive force

T = hot junction temperature 

K = constant 

teh relationship that applies to a thermocouple is:

The pressure of 1 bar equals to:

a manifold pressure gaug of a piston engine measures:

bar in psi   und 1 Bar in Pascal

The probe used to measure the air intake pressure of a gas turbine engined powerplant is:

Different pressure sensor are used according to the intensity of teh pressure measured (low/medium/high) Classify the following sensors by order of increasing pressure for which they are suitable?

1) bellow type

2) Bourdon tube type

3) aneroid capsule type

The engine instrument utilising an aneroid pressure diaphragm is the:

An aneroid  capsuele:

1) measures differential pressure

2) measures absolute pressure

3) is used for low preesure measurement

4) is used for very high pressure measurement 

in a capacitance fuel gauge => Formula?

The principle of capacity gauges is based on :

The gauge indicating the quantity of fuel measured by a capacity gauging system can be graduated directly in weigh units because the dielectric constant of fuel is:

The indication of a fuel foat gauge varies with: 

1) aircraft attitude

2) accelerations

3) atmospheric pressure

4) fuel temperature
