QUESTIONS WITH COMPLETED CORRECT
ANSWERS!!
what are the 5 basic navigation systems? Answer - 1. pilotage - flying by
landmarks
2. dead reckoning - knowing your heading and speed, work out where you're
going
3. celestial navigation - using time and angle bwtn known celestial object
(moon, sun, etc)
4. radio navigation - GPS, ILS, VOR, ADF, etc
5. inertial navigation - INS and ADIRU
what is INS? what does it stand for? Answer - - inertial navigation system
- advanced navigation concept designed as an integral part of the avionics
system
- provide steering commands to autopilot to steer the airplane through
predetermine waypoints
- accurately determine an AC position using internal sensing devices
what are some features of INS? Answer - 1. auto self-alignment and calibration
are accomplished each time the INS is turned on
2. does not require any input from navigation aids external to the AC
3. continuously monitors its on performance and warns when signals are
unreliable
4. present position, waypoint and destination data are easily entered by using a
keyboard
, 5. performance can be improved during flight by making a position fix when
accurate present position reference is available
what are the 3 laws of motion? Answer - 1. body continues in a state of rest, or
uniform motion in a straight straight line, unless acted on by an external force
2. the acceleration of a body is directly proportional to the sum of the forces
acting on that body
3. for every action, there is an equal and opposite reaction
an aircraft moves in 3 dimensions over the earth's surface, how many degrees
of freedom? Answer - 6 degrees of freedom
- 3 translation (N/S, E/W, UP/DWN)
- 3 rotational (roll, pitch, and azimuth)
what is a gimbal platform Answer - - plat that effectively decouples the inertial
reference system from the airframe and provides all-attitude freedom and
rotation
- AC are seldom perfectly lvl in flight, all airborne accelerometers must be
mounted on gimbal plat
- consist of 3 gyros, which stabilize the unit
the combo of gimbals and gyroscopes creates a platform that.... Answer - -
remains level in any AC attitude
- does not sense changes in AC attitude, the output signal accurately measures
changes in accel
- signal is amplified and sent to INS comp
INS is capable of continuously updating what? Answer - -position
-ground speed
