PRESSURE HEADS

#1. A pitot head is used to measure:

• Adynamic minus static pressure.
• Bstatic plus dynamic pressure.
• Cstatic pressure.
• Ddynamic pressure.

#2. A static vent is used to measure:

• Adynamic pressure minus pitot excess.
• Bdynamic pressure plus pitot excess.
• Catmospheric pressure.
• Dpitot excess pressure.

#3. A pressure head is subject to the following errors:

• Aposition, manoeuvre induced, temperature.
• Bposition, manoeuvre induced.
• Cposition, manoeuvre induced, density.
• Dposition, manoeuvre induced, instrument.
