Correct Answer : Mach number
Explanation : Mach number is used for programming stabilizer position for speed stability, defining high speed performance boundaries such as flutter onset, and for defining optimal cruise paths.
Correct Answer : Option (D) : Standoff constant error
Explanation : A stand off constant error exists since the direction of the local vertical changes as a result of both the rotation of the Earth and the aircraft’s own motion around the Earth.
Correct Answer : Option (A) : Use higher order leveling loop
Explanation : The stand off error depends upon the gravity sensors switch’s dead and gives poor acceleration errors. Significant improvement can be obtained in the averaging vertical reference by using a high order leveling loop.
Correct Answer : Option (A) : Maxwell
Explanation : The magnetic fields B are measured in Gauss and Tesla(104 Gauss). In geomagnetism, Units of “Gamma”(10-5 )are used.
