INS 1: Pitot-static

 

Q1. When aircraft is side slipping to the right:

pressure sensed by right static port will be more than left static port.

Q2. Pitot source is always fitted under the wing of an aircraft.

No

Q3. A blocked static vent will affect?

All of the above.

Q4. Where an alternate static source is fitted, use of this source usually leads to:

an increase in position error

Q5. A pressure head is subject to the following errors:

position, manoeuvre-induced, instrument

Q6. Positioning of the pitot tube must be:

outside the boundary layer.

Q7. A pitot head is used to measure:

static plus dynamic pressure

Q8. Pressure-Position error is maximum at:

higher angle of attack and lower airspeed

Q9. All the pressure instrument takes input from Static source

TRUE

Q10. Given: Pt = total pressure, Ps = static pressure, Dynamic pressure is:

Pt – Ps

Q11. The vertical speed indicator (VSI) is fed by?

Static pressure.

Q12. Manoeuvre induced error is:

short term.

Q13. The altimeter is fed by?

Static pressure.

Q14. A static vent is used to measure:

atmospheric pressure

Q15. Opening of static port or head must be _______ to the airflow.

perpendicular

Q16. A pitot tube covered by ice that blocks the ram air inlet will affect the following instrument(s)?

Airspeed indicator only.

Q17. Pitot tube will be always parallel to the airflow even when you are changing Pitch or Bank.

FALSE

Q18. When aircraft yaws to the right:

pressure sensed by left static port will be more than right static port.

Q19. The error in altimeter readings caused by the variation of the static pressure near the source is known as?

Position pressure error.

Q20. Drain holes are usually fitted in pitot or combined pitot static probe:

to drain the water, it will slightly affect the pressure.

Q21. The pitot tube comprises a mast to position it away from the skin of the aircraft to:

avoid disturbance from aerodynamic flow about the aircraft

Q22. Fitting static vents to both sides of the aircraft fuselage will:

balance out errors caused by side slipping or yawing

Q23. Position error:

may be reduced by the fitting of static vents

Q24. As the angle of attack increases the pressure position error will:

Increase

Q25. Error in pressure sensed by the aircraft pitot/static during change of flap position and landing gear operation is referred as:

Position pressure error

Q26. Manoeuvre induced error:

is caused by pressure changes at static probes or vents

Q27. All the pitot and static sources suffer from pressure position error?

yes

Q28. Slots/holes in static head is usually __________ to the airflow when the aircraft is __________.

perpendicular; Level flight.
