MAM Aircraft systems and Instrumentation Question Bank
Part – A
Short Questions :
1) Name any four modern control systems?
– Fly by wire (computer):- May be Analog computer or digital computer
Related : MAM School of Engineering AE2204 Elements of Aeronautics B.E Question Bank : www.pdfquestion.in/3197.html
– Fly by optics (light):-
– Power by size (user electro-hydraulic actuators
– Intelligent flight control system
2) What do you mean by active control technology? Give at least three examples? Activate control technology helps to improve the handling of aircraft and to reduce the time lag or control delays by increasing the no. of computers, etc., in the aircraft (i.e. redundancy). This advance concept in applicable to following e.g..
Examples are:-
– Fly by wire
– Control configured vehicles
– Automatic flight control system.
3) Name any four communication system?
HF (High Frequency) communication for long range
– VHF (Very High Frequency) communication for short range
– Sat Com (Satellite Communication)
– ACARS/AIRCOM
4) Name any four navigation system?
– VHF Direction Finder (VDF)
– NDB
– ADF
– GPS
5) What is INS used for?
Ins (Inertial Navigation System) is a sophisticated system for continuously calculating the aircraft track, ground speed and then convert this information in to other useful data.
6) Differentiate between instrument landing system and Microware landing system?
– In MLS, the A/C can approach from different directions, rather than having to fly to a position on the extended centerline of the run Cray in use.
– MLS guidance is more accurate than ILS.
– MLS increases the no. of A/C that can approach at name time.
7) What do you mean by VOR & CCV?
VOR means (Very High Frequency Omni range)
(Ref. to your notes as text book)
CCV means (Control configured Vehicle)
(Ref. to your care study)
8) What is ADF & NDB?
– ADF means automatic direction finder
(See notes or Text book)
– NDB mean non directional beacons
(See notes or text book)
9) What is SELCAL & Sat Con?
SEL CAL – (selective calling)
See notes
10) Differentiate between electric trim and manual trim? Electric trim is usually used to reposition stabilizer. Manual trim is used to override the elective trim.
11) What is difference between speed brakes and spoilers?
Speed brakes are used for reducing the speed of A/C by increasing the drag. They also act as spoilers to spoil the lift Spoilers are used to spoil the lift for descending or landing.
12) Name any four control system components?
– Bell crank
– Walking beam
– Sector & Quadrant
– Torque tube
13) What is stabilators, ruddervators and flaperons?
STABILATOR = STABILIZER + ELEVATOR
(MOVABLE)
RUDDERVATORS = RUDDERS +ELEVATORS
FLAPERONS = FLAP + AILERONS
14) What is aileron differential control system? Movement of control stick moves one ailerons up greater than the other down words.
15) What is the use of yaw dampers in rudder control system? Yaw damper systems operate continuously in flight to improve the airplane’s directional stability and turn coordination. Dampers actuators are powered hydraulically.
Part – B
1) What are the functions of push pull and flexible push pull red system? Explain with neat diagram?
2) Explain how fully powered flight control system and power boated flight control system work?
3) Explain the merits (advantage) and demerits (disadvantage) of analog and digital fly by wire flight control system?
4) Explain the working and the advantage of auto pilot system?
5) Explain INS, ILS, MLS, VOR, ADF, NDBR selcal communication with neat diagram?
6) Explain the working of any two Engine control system with neat sketcher?
7) Explain sequence value, Debooster value, relacter value, shutt off value Cressfeed value?
8) Explain with neat diagram the working of typical hydraulic far B-727 cross feed value?
9) Explain shimmy dampers in rose gears Air-oleo spring oleo shock struts in main landing gears?
10) Clan its airbrakes? Describe Expander tube brake system explain its working?
11) Differentiate between fuel system of piston and jet engine?
12) Explain lubrication system used for piston and jet engine? Also explain electronic engine control?
13) Explain the starting system for the A/C? List out the gar turbine engine starters explain with neat diagram?
14) Describe the fuel system for B 747 A/C with neat diagram?
15) Explain high & low voltage capacitor type ignition system.
16) Explain with neat sketcher the air cycle cooling system and vapor –cycle cooling system of an A/C
17) Explain icing do-icing and anti -icing? Discus pneumatic de-icing system?
18) What are cooling pales? Explain?
19) Explain the working of different fire detection and smoke detection techniques used in A/C with neat sketches?
20) Classify different type of oxygen system? Explain solid state oxygen systems? Write down its advantages?
