The 1 in 60 rule combined with Speed/Distance/Time assumptions is the basis of many other ‘rules of thumb’ that can be useful in pilot navigation (or to check that an FMS-calculated track makes sence. For example: At 120 kt groundspeed, the aircraft travels 60nm in 30 minutes.
Knowing the formulas on how to calculate time, speed, and distance as a student pilot is essential. The easiest way to remember the formulas is to remember that to solve for distance you are always multiplying.
Here is the formula you are looking for: (You can use this formula to answer your first question. I'm not entirely clear on what the second question means.) Here is a nice discussion of the time/distance check from the Flight Learnings website: time/distance to station
Time, Distance, and Speed Calculations: Utilizing a simple formula (Distance = Time x Ground Speed may be utilized; Therefore, if you have any two, you can calculate the other; Time Calculations: If you need to travel 10 NM, and you have a ground speed of 100 knots, how long will it take? 10 NM = Time (hours) x 100; 10/100 = Time; Time = 0.1
The declared distances to be calculated for each runway direction comprise: the take-off run available (TORA), take-off distance available (TODA), accelerate-stop distance available (ASDA), and landing distance available (LDA).
Aircraft Performance & Calculations. Accident investigations have discovered causal factors resulting from unreasonable expectations of aircraft performance – especially when operating at the edges of the aircraft weight and balance envelope.
We now know how to calculate the altitude gained or lost for each degree of pitch change over a given distance; 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; First, lets convert speed to NM/MIN, since the 60-to-1 rule is based on TAS expressed in NM/MIN
