5. Heading Indicator - Vacuum driven
6. Vertical Speed Indicator- Pitot Static
Indicated Airspeed is what the Airspeed Indicator reads. Indicated airspeed is the airspeed read directly from the airspeed indicator on an aircraft, driven by the pitot-static system. It uses the difference between total pressure and static pressure, provided by the system, to either mechanically or electronically measure
Calibrated Airspeed (CAS) is Indicated Airspeed corrected for Instrument and position error. When flying at sea level under Standard Atmosphere conditions (15 °C, 1013 hPa, 0% humidity) calibrated airspeed is the same as equivalent airspeed (EAS) and true airspeed (TAS).
True Airspeed (TAS) is the aircraft speed relative to the airmass in which it's flying. *(corrected for winds)
14CFR91.159 Note : "Odd [or Even] thousand feet plus 500". 5000 is an odd thousand even though it is an even number.
§ 91.159 - VFR cruising altitude or flight level.
Except while holding in a holding pattern of 2 minutes or less, or while turning, each person operating an aircraft under VFR in level cruising flight more than 3,000 feet above the surface shall maintain the appropriate altitude or flight level prescribed below, unless otherwise authorized by >ATC:
(a) When operating below 18,000 feet MSL and—
EAST:: (1) On a magnetic course of zero degrees through 179 degrees, any odd thousand foot MSL altitude 500 feet (such as 3,500, 5,500, or 7,500); or
WEST:: (2) On a magnetic course of 180 degrees through 359 degrees, any even thousand foot MSL altitude 500 feet (such as 4,500, 6,500, or 8,500).
Pressure Altitude is the altitude of the aircraft if it were a standard day
Pressure Altitude can be found if sitting in airplane at the airport, by dialing in 29.92 in Colemans window and reading the altimeter.
Density Altitude is Pressure Altitude corrected for non-standard temperature
Higher the density altitude the worse the performance. Density Altitude is how the plane will perform given the current temperature.
Subtract the current altimeter setting from the standard pressure of 29.92.
Multiply by 1,000.
If you have a negative number, subtract it from the field elevation. Add a positive number.
Example: A3002 = 30.02 in. Standard is 29.92 in.
30.02-29.92 = .10
.10 X 1000 = 100 (ft). KMMU Field Elevation approx 200 ft + 100 ft = 300 ft Pressure Altitude.
Density altitude in feet = pressure altitude in feet + (120 x (OAT - ISA temperature))
Pressure altitude is determined by setting the altimeter to 29.92 and reading the altitude indicated on the altimeter.
OAT stands for outside air temperature (in degrees Celsius).
ISA stands for standard temperature (in degrees Celsius).
A standard temperature lapse rate is when the temperature decreases at the rate of approximately 3.5 °F or 2 °C per thousand feet up to 36,000 feet, which is approximately –65 °F or –55 °C. Above this point, the temperature is considered constant up to 80,000 feet.
Below water, compression diving, must wait 24 hours if we have to climb >8000 ft.
Nitrogen is absorbed in blood during diving,
Nitrogen wants to bubble up when climbing in airplane.

EXPLANATION… A TOMATO FLAMES is one of the most popular acronyms you will run into as a student pilot. It begins first off with our altimeter followed by our tachometer and then the oil temperature gauge *The first snag you may run into is the manifold pressure gauge. The reason there is an asterisk next to this is because it’s only applicable if your airplane has a constant speed propeller (which most 150’s 140’s and 172’s do not) if your airplane does not have a manifold pressure gauge, it’s not required in your aircraft to be working. As we continue in the acronym we need and airspeed indicator. **The temperature gauge is for each liquid cooled engine, so if you have two engines, you need two temperature gauges. We continue on with our oil pressure gauge. The interesting about fuel gauges is that they only need to read correctly at full and at empty everything in between apparently doesn’t matter. So if your fuel gauges are not reading correctly when the tanks are perfectly full or dead empty then they are not deemed airworthy. ***If you have a fixed gear airplane, you will not need landing gear extension lights. **** Only if your aircraft was manufactured after March of 1996. You also need a magnetic compass, ELT transmitter and seatbelts.
