During the HABUT FOUR departure from SBA, what is the minimum rate of climb required to reach 6,000 feet with a ground speed of 120 knots?

To determine the minimum rate of climb required to reach 6,000 feet with a ground speed of 120 knots during the HABUT FOUR departure from SBA, it's essential to understand the relationship between altitude gain, ground speed, and time.

To calculate the rate of climb in feet per minute, you first need to convert the ground speed from knots to feet per minute. Since there are 6076 feet in a nautical mile and 60 minutes in an hour, you can calculate the feet per minute as follows:

Ground speed in feet per minute = Ground speed in knots × 6076 feet/nm ÷ 60 minutes/hour.

Here, for a ground speed of 120 knots:

120 knots × 6076 feet/nm ÷ 60 minutes/hour = 12,032 feet per minute.

Next, to find out how long it takes to climb to 6,000 feet, you use the formula:

Time (in minutes) = Altitude to be gained (in feet) ÷ Rate of climb (in feet per minute).

If we want to climb to 6,000 feet, we can express the required rate of climb as:

Rate of climb = Altitude to be gained (in feet) ÷ Time
