Which statement best describes the Inertial Navigation system compared to the inertial reference system ?

the irs uses a ring laser gyro which has no moving parts, relying on laser beams to measure aircraft angular acceleration

An aircraft is conducting an ILS approach and is exactly on the glideslope as it passes over the outer marker Assuming QNH correctly set you would expect the altimeter to to? Conditions are PA 3000ft and temp +30°

under read

True Mach number (TMN) is indicated Mach number corrected for ?

pressure and instrument error

An aircraft is in flight within rated coverage of an NDB. The aircraft has a fixed card ADF tuned to that NDB ad is receiving reliable indications. If the aircraft heading is 040 and the Head of the needle reads 320 relative, which best describes the magnetic bearing of the aircraft from the NDB ?

180

An aircraft is climbing at a constant Mach number through ISA tropospher. You would expect TAS too?

decrease

An aircraft is flying at FL330 in ISA conditions at a constant Mach no. If the aircraft flies into a pool of air which is ISA+10 and the Mach number remains unchanged. Which best describes the effect on IAS

IAS would remain unchanged

DME radio waves follow ?

great circle tracks

AIP rated coverage for an aircraft flying at FL390 tracking toward a DME beacon which is sited 4000ft amsl is

180

An aircraft is flying wings level heading 270 and decelerating which answer is correct relating to the floating magnetic compass ?

it would indicate and apparent turn to the north

An inertial reference system has a max radial error formula of 3+3T - Which answer best describes the max radial error permissible on a single flight in Nav mode for 8hours ?

The static port becomes blocked as the aircraft climbs. What effect could this have on the accuracy of the readings taken from the ASI

IAS would underread

What statement is most correct about the properties of the rhumb line and great circles depicted on a polar stereographic chart ?

both rhumb lines and great circ,es are straight but rhumb lines are closer to the pole

It is 1500hrs LMT on the 120°E meridian. What is the time expressed in UTC ?

0700

what answer best represents the amount of gyroscopic ERP you could expect if an aircraft is flying at 30°S

8° per hour

An aircraft is travelling due north. Which of the wind direction/speed options would produce the max distance to the PNR ?

nil wind

Whilst in flight the pilot manually mis aligns the RMI compass card. If No.1 needle is set to ADF and No.2 is set to VOR, which of the statements below is most correct ?

The VOR needle will turn with the compass card and display correct bearing information and the ADF needle will disply incorrect bearing information continuing to point at th station

Which of the answers below best describes inflight updating of an INS or IRS

it may be manually updated over a VOR

Two aircraft are flying due north on different meridians in the northern hemisphere. Which statement is most correct ?

the aircraft will converge on each other as the approach the North Pole

Which best represents the possible errors in an ILS ?

course reversal and multi pathing due to interference from other aircraft

Which is most correct about factors involved in the calculation of earth transport precession and earth rate precession?

ERP is a function of the Sine of the latitude at which the aircraft is flying and is greatest at the poles. ETP is a function of the number of meridians crossed in one hour, multiplied by the sin of the mid latitude.
