Which instruments are used with pitot static
Airspeed, vertical speed, altimeter
Which instruments are used by gyroscopes
Attitude indicator, turn coordinator, heading indicator
What is standard pressure and temperature
29.92 inches of mercury and 15 degrees Celsius
How does the pressure and temperature change in a standard lapse rate
-2 degrees every 1000 ft, -1inch Hg every thousand ft
Why is heading indicator more relatable then compass
Compass has many errors due to magnetic dip, head indicator doesn’t work with magnet so it doesn’t have those errors
How does the pitot static system work
The pressure from the ram air going into the pitot tube and air from static port gets measured and moves dials / gimbals accordingly
What are the rules when flying low to high pressure
Low to high, high in the sky. You are actually higher then altimeter is reading
What are the rules when flying from high to low pressure
High to low, look out below. You are flying lower then altimeter is reading
How does the pitot static system in a glass cockpit work
The air data computer or ADC senses the pitot tube and static port differential
What is AHRS
Attitude heading reference system, used in glass cockpit
When is the only phase of flight compass is accurate
Straight and level
How are magnetic north and true north different
True north is at top of the earths axis while magnetic north is where the earth magnetic field is
What is the difference between true north and magnetic north called
Compass variation
What is compass deviation
When the materials in aircraft affects the way the compass reads, we use complains deviation card in cockpit to correct for this
Due to magnetic dip when flying a north or south heading, what happens
Compass doesn’t read accurate so make sure you undershoot north and overshoot south when turning
U.N.O.S
Does temperature affect compass readings?
Yes, when weather is hot, the air expands which can lead you to be higher and when air is cold pressure decreases, which leaves you lower
Is there anyway to correct for temperature regarding a compass?
No, just give yourself a little bit of extra room, depending on the weather
What’s a PFD
The primary flight display a glass carpet display all of your instruments
What is an MFD
It’s a back up PFD can be used if it fails, but also shows things like traffic, weather and charts
