An aircraft in the northern hemisphere makes an accurate rate one turn to the right. If the initial heading was 330°, after 30 seconds of the turn the direct reading magnetic compass should read:
Considering a stabilised platform inertial system: 1) The rate gyros and the accelerometers are mounted on the same platform. 2) The rate gyros and the accelerometers are mounted on two separated platforms. 3) The principle of operation requires only one rate gyro. 4) The principle of operation requires at least 2 accelerometers. The combination that regroups all of the correct statements is:
The sensing principle of a ring laser gyro uses:
During a Boeing 747-400 multiple-autopilot automatic landing with LAND 3 or LAND 2 annunciated, what pitch-mode transition occurs at approximately 50 ft radio altitude?
When turning into a desired radial, FD bars indicate:
In an autopilot system, the basic stabilisation modes are: 1) Altitude hold. 2) Pitch attitude hold. 3) Roll attitude hold. 4) IAS hold. The combination regrouping all the correct statements is:
The diagram representing a left turn with insufficient rudder is:
If the static source to an airspeed indicator (ASI) becomes blocked during a descent the instrument will:
Machmeter readings are subject to:
A Machmeter may derive Mach number from the ratio of impact pressure to static pressure. With Pt denoting total pressure and Ps denoting static pressure, which expression gives that particular ratio?
