Airspeed Indicator | Errors Flashcards
The instrument will ___ indicate in a sideslip
wrongly
If dynamic pressure is captured by the static port, the ASI will ___read
under
The static pressure is ___ along the fuselage in flight, causing the ASI to ___read
lower, over
Changes in air density affect the dynamic pressure, and will make the ASI ___read at altitude
under
Over 300kts, the air in the pitot tube will end up ___ dense than usual, requiring a correction
more
At high altitude, with ___ air, the air flowing into the capsule is more easily compressed and will make the instrument ___-read
thinner, over
If the pitot tube and drain are blocked, the ASI will behave like an ____, as it will only have static information.
altimeter
With the pitot tube and drain blocked, the readings will ___ as you climb, ___read in a descent, and not change when the airspeed varies.
increase under
As static pressure increases, the ASI reading will ____
decrease
If the drain hole remains open, the IAS will read ___ as there is no difference between static and dynamic pressure
zero
A leak in the pitot total pressure line of a non-pressurised aircraft would cause an ASi to ___read
under
With the static port blocked, the pressure inside remains ___
the same
With the static port blocked, the ASI will read correctly in the cruise as long as the OAT doesn’t change. In the descent it will ___read because the static element of the pitot pressure increases inside of the capsule.
over
