Question

The helicopter's present altitude (AGL) and airspeed must be such that the DECL mode can achieve _____ knots prior to reaching __________, with a .5 knot per second deceleration rate.

Answer 1

To achieve the required velocity in the DECL mode, the helicopter's present altitude and airspeed must be calculated using the given deceleration rate.

Step-by-step explanation:

In order for the DECL mode to achieve a certain deceleration rate, the helicopter's present altitude (AGL) and airspeed must be such that it reaches a certain velocity prior to reaching a certain point, with a specified deceleration rate.

Let's say the required velocity is 'v' knots and the distance to the point is 'd' nautical miles. Given that the deceleration rate is -0.5 knots per second, we can use the equation v = u + a * t, where 'u' is the initial velocity, 'a' is the deceleration, and 't' is the time taken.

Using the equation v = u + (-0.5) * t, we can plug in the values of the initial velocity, deceleration, and time taken to find the required velocity at the specified point.
