CR7 number 1

the function of the synchronising system of a gyromagnetic compass is to

• maintain the gyro in alignment with the magnetic reference

• hold the gyros in the Aircraft's yawing plane

• Ensure the gyro spin speed remains constant

The airspeed indicator circuit consists of pressure sensors. the pitot tube directly suppliers

• the static pressure

• the dynamic pressure

• the total pressure and the static pressure

• the total pressure

In a strapdown inertial system, the acceleration are measured in a trihedron which is fixed regarding to the

• absolute space

• earth's trihedron (X,Y,Z)

• Aircraft's trihedron (pitch, roll & yaw axis)

• earth's trihedron (longitude, latitude)

A temp sensor has a "recovery factor" of 0,75. This means that it will measure

• 75% of SAT plus total ramrise

• 75% of SAT plus total ramrise

• 75% of TAT

• SAT +75% of total ramrise

without readjusting the barometric setting of the altimeter, it will unread when

• flying from a high pressure area into a low pressure area

• flying in headwind with constant barometric pressure

• flying in tailwind with constant barometric pressure

• flying from a low pressure area into a high pressure area

what does a radio altimeter, for an aircraft in the landing configuration measure?

• height of aircraft wheels above the ground

• height of aircraft above the ground

• altitude of aircraft

• altitude of aircraft wheels

the captain of an aircraft intend to descend with highest possible groundspeed to land on schedule. He therefore decides to descend using the speeds Vmo & Mmo. which of the following statements is correct during the descent from high level ?

• first, Vmo will first be limiting, then Mmo

• first Mmo will first be limiting , then Vmo

• Vmo & Mmo are equally limiting

• neither Vmo or Mmo will present any limitation to this descent

the dashpot assembly in an IVSI is used to alter

• case pressure to reduce lag

• case pressure to reduce pressure error

• capsule pressure to reduce pressure error

• capsule pressure to reduce lag

when accelerating on an easterly heading in the northern hemisphere, the magnet system of a direct reading compass will

• turn clockwise , indicating an apparent turn towards south

• turn anti-clockwise , indicating an apparent turn towards south

• turn anti-clockwise , indicating an apparent turn towards north

• turn clockwise , indicating an apparent turn towards north

artificial horizon turning errors cause

• bank errors due to centrifugal forces produced by the fore and aft vanes and air jets

• bank error due to centrifugal forces produced by the pendulous mass

• pitch errors due to centrifugal forces produced by the port/starboard vanes and air jets

• pitch errors due to centrifugal forces produced by the...
