In a non-pressurized aircraft, if one or several static pressure ports are damaged, there is an ultimate emergency means for restoring a practically correct static pressure intake:

1) The QFF at an airfield in California located 69 metres below sea level is 1030 hPa. The air temperature is 100C lower than a standard atmosphere. What is the QNH?

2) You must make an emergency landing at sea. The QNH of a field on a nearby island with an elevation of 4000 ft is 1025 hPa and the temperature is -200C. What is your pressure altimeter reading when landing if 1025 hPa is set in the subscale?

3) A pitot blockage of the ram air input with the static port open causes the airspeed indicator to:

4) In a non-pressurized aircraft, if one or several static pressure ports are damaged, there is an ultimate emergency means for restoring a practically correct static pressure intake:

5) The total pressure probe (pitot tube) comprises a mast which removes its port to a distance from the aircraft skin in order:
