TAS = 150 + (2% X 3) (150) = 150 + (.As was mentioned previously, one of the more important aspects of quantitative data is the ability to use it for comparison.So, the following equation could be used: TAS = IAS + (2% per 1,000 FT) X (IAS).TAS increases over IAS at the rate of 2% per 1,000 feet altitude increase.

If we don't have a TAS indicator, TAS can be computed from IAS.NM/MIN can be obtained easily from TAS as follows: NM/MIN = TAS/60.First, lets convert speed to NM/MIN, since the 60-to-1 rule is based on TAS expressed in NM/MIN.Throw in a time factor using True Airspeed (TAS) expressed in NM per MIN and we can relate this pitch change to a change in VSI.

We now know how to calculate the altitude gained or lost for each degree of pitch change over a given distance.1° = 100 FT at 1 NM (1° climb or descent gradient results in 100 FT/NM).1° = 1 NM at 60 NM (60 NM from the station, there is 1 NM between each radial).Find out what your turn radius is at cruise airspeed up high and at approach airspeed down lower find out what a 1° pitch change will do to your VVI and remember those numbers.You need to use the formulas before you fly.The 60-to-1 rule gives us a mathematical equation to help you figure out all these questions, but it is almost impossible to run these calculations and fly at the same time.

It is an alternative to the TLAR (That Looks About Right) method of flying.

It reduces the pilot's workload and increases efficiency by requiring fewer changes and less guesswork.

It allows the pilot to compute the pitch changes necessary when establishing an attitude during the control and performance concept of attitude instrument flying.

The 60 to 1 rule is is a technique for establishing predictable pitch changes for climbs or descents and lead points for intercepting courses or arcs.

Look above time to get pounds burned in that time.

Point the big black arrow to the pounds per hour (burn rate).

Note that you will travel 10% of your speed in 6 minutes (6 min * 10 = 60 minutes).

Find the big black arrow, it is pointing to your ground speed.

Line up distance over time (outer wheel over inner).

Read time immediately below (inner scale) the number representing distance.

Look for the distance to travel on the outer wheel.

Point the black arrow to match the expected ground speed.

One degree of course change will put you 1 NM off course after 60 NMs.

Temperature-Dew Point (☏) divided by 4 = Base of clouds.

Temperature-Dew Point (☌) divided by 2 = Base of clouds.

This is a very rough formula as cloud bases are not always flat and can change rapidly.

Used for VFR planning or when icing is a concern.

Other tools are available to help you calculate density altitude such as Pilot Friend's Density Altitude Calculator.

Next move left and read your density altitude off the scale.

From the temperature on the bottom move up to your pressure altitude.

ISA Temp (using standard Lapse rate of -2 degrees C per 1000 ft) is 14° C.

Pressure Altitude = 600' (as calculated above).

Pressure altitude corrected for non-standard temperature.

Notice this table is more designed for Celsius to Fahrenheit but we still come out just over 21☌.

Find the temperature you need and read across the appropriate column.

In this example it comes out to be roughly 22☌.

Move down and read the temperature off of the bottom.

Move across until you hit the reference line.

Start at your initial temperature on the Fahrenheit scale.

is used to operating on the Fahrenheit scale for day to day life but aviation standard is Celsius Temperature Conversion Table Temperature Conversion: Using the widely accepted WGS84 ellipsoid model, this averages a nautical mile to 6,076 feet (1,852 meters), or 1.15 statute miles

Nautical Mile: defined as one minute of arc along a meridian of the Earth.

Statute Mile: the same as a standard mile as you would see driving a car.
