Notes 3 Flashcards
The accuracy of an HSI Should always be checked against the _________________
magnetic compass.
roll into a standard rate turn to the right from a westerly heading in the Northern Hemisphere, compass will
indicate the approximate correct magnetic heading if the roll into the turn is smooth.
Pitot and and stati source is blocked
The altimeter will read higher than normal, airspeed greater than normal, and the VSI will momentarily show a climb. This is due to lower pressure inside the cabin.
80° steep turn is made to the right and the aircraft is rolled out to straight-and-level flight by visual references, the attitude indicator
may show a slight climb and turn.
What would be the indication on the VSI during entry into a 500 FPM actual descent from level flight if the static ports were iced over?
Air is trapped and it will be zero
During normal coordinated turns, what error due to precession should you observe when rolling out to straight-and-level flight from a 180° steep turn to the right?
The miniature aircraft would show a slight turn indication to the left.
pretakeoff check of heading indicator
After 5 minutes, set the indicator to the magnetic heading and check for proper alignment after taxi turns.
What indication is presented by the miniature aircraft of the turn coordinator?
Indirect indication of the bank attitude.
What should be the indication on the magnetic compass as you roll into a standard rate turn to the left from a north heading in the Northern Hemisphere?
The compass will initially indicate a turn to the right.
The horizon bar or Miniature Airplane should erect and become stable within 5 minutes.
horizon bar
This is the principal of rigidity?
gyro depends upon for operation is the resistance to deflection of the spinning wheel or disc.
What can you do to fix a blocked static port?
Use the alternate static source or break the glass on the vertical speed indicator.
What does the miniature aircraft of the turn coordinator directly display?
Rate of roll and rate of turn.
During normal operation of a vacuum driven attitude indicator, what attitude indication should you see when rolling out from a 180° skidding turn to straight-and-level coordinated flight?
The miniature aircraft shows a turn in the direction opposite the skid.
explain skidding and slipping turn
