## How do you calculate travel time?

**Estimate** how fast you will go on your **trip**. Then, divide your total distance by your speed. This will give you an estimation of your **travel time**. For example, if your **trip** is 240 miles and you are going to be **drive** 40 miles an hour, your **time** will be 240/40 = 6 hours.

## How do you manually calculate flight times?

**Basic Calculations**

**Time**T = D/GS. To find the**time**(T) in**flight**, divide the distance (D) by the GS. The**time**to fly 210 NM at a GS of 140 knots is 210 ÷ 140 or 1.5**hours**.- Distance D = GS X T. To find the distance flown in a given
**time**, multiply GS by**time**. - GS GS = D/T. To find the GS, divide the distance flown by the
**time**required.

## How long before a flight should I be at the airport?

We advise that you arrive at least two hours **before** your **flight** to allow plenty of extra time to check-in and pass through security.

## Why do I have to check in 3 hours before flight?

## How do you calculate flight speed?

**Mach Number:**

**Formula**: Mach Number =**Aircraft Speed**/**Speed**of Sound (dependent on altitude)- Example:
**Aircraft**is**flying**at 30,000′**Speed**of sound at 30,000′ = 589.4 knots. The airspeed is 489.3 knots. **Calculate**: 489.3/589.5 = 0.83 Mach.

## How do you calculate flight hour cost?

**Cost** per **flying hour** (CPFH) is a well-known DoD **cost** metric. As the name suggests, CPFH is calculated as an **aircraft** fleet’s **costs** divided by its **flying hours**: CPFH = Total O&S **Costs** Total **Flying Hours**.

## What is the plane’s average speed?
