Module 5. Digital techniques / Electronic instrument systems
In a flight director, how are small deviations corrected? • Pilot input. • Instrument is calibrated at fitment to remove any possible error. • Instrument feedback.
The centre of gravity of an aircraft is adjusted by two weights, 10 kg and 5 ckg plaed 4m and 2 m aft of the c of g. To what position must a 20 kg weight be added to balance the c of g? • 2.5m. • 4m. • 2m.
Heavy corrosion deposits on clad aluminium alloys should be removed • chemically by use of phosphoric acid. • chemically by use of trichloroethylene. • mechanically using a pneumatic vibrator.
Diverdeep asking: • usually, in heavy deposits corrosion, the initial phase is remove the bulk with a brass wire wheel and than use the acid
