Q

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?

A

No change until an actual climb rate is established, then indicated airspeed will increase.

Q

If the outside air temperature increases during a flight at constant power and at a constant indicated altitude, the true airspeed will.

A

True airspeed will increase and true altitude will increase.

Q

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?

A

The altimeter will read higher than normal, airspeed greater than normal, and the VSI will momentarily show a climb.

Q

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?

A

The VSI pointer would remain at zero regardless of the actual rate of descent.

Q

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

A

May take off under IFR and use a 100 feet descent as the zero indication.
