Pitot Static System Flashcards
During flight, if the pitot tube becomes clogged with ice which of the following instruments would be affected?
The airspeed indicator only.
If both the ram air input and the drain hole of the pitot system are blocked, what reaction should you observe on the airspeed indicator when power is applied and a climb is initiated out of sever icing conditions?
No change until an actual climb rate is established, then indicated airspeed will increase.
What indication should a pilot observe if an airspeed indicator ram air input and drain hole are blocked?
The airspeed indicator will react as an altimeter.
If both the ram air input and drain hole of the pitot system are blocked, what airspeed indication can be expected?
No variation of indicated airspeed in level flight even if large power changes are made.
If the outside air temperature increases during a flight at constant power and at a constant indicated altitude, the true airspeed will.
True airspeed will increase and true altitude will increase.
If, while in level flight, it becomes necessary to use an alternate source of static pressure vented inside the airplane, which of the following should the pilot expect?
The altimeter to read higher than normal.
If, while in level flight, it becomes necessary to use an alternate source of static pressure vented inside the airplane, which of the following variations in instrument indications should the pilot expect?
The altimeter will read higher than normal, airspeed greater than normal, and the VSI will momentarily show a climb.
If, while in level flight, it becomes necessary to use an alternate source of static pressure vented inside the airplane, which of the following should the pilot expect?
The vertical speed to momentarily show a climb.
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?
The VSI pointer would remain at zero regardless of the actual rate of descent.
You check the flight instruments while taxiing and find the vertical speed indicator (VSI) indicates a descent of 100 feet per minute. In this case, you
May take off under IFR and use a 100 feet descent as the zero indication.
What information does a Mach meter present?
The ratio of the aircraft true airspeed to the speed of sound.
