From the outback of northern Australia, to the jungles of Vietnam and the mountains of Papua New Guinea and Nepal – plus much of the US, time in the Philippines, Columbia and Russia, David Earley is one well travelled helicopter pilot.

Along the way he has held almost every position from line pilot to a helicopter company CEO overseeing $47 million in annual revenue on some of the largest Australian government helicopter contracts. He is also a licensed A&P mechanic.

David started out flying the Bell 47 in the Australian Army during which time he spent 12 months at war in Vietnam as a scout pilot. Post-war David held a number of positions in the Army before moving to JAARS where he spent 15 years in PNG and the US.

His duties here not only included providing support to remote teams in the PNG highlands but the standing up of a helicopter training school and check and training.

From here David held a number of roles leading to the position of CEO of Reef Helicopters which became Australian Helicopters. All of which is covered in his book ‘Beneath Blades – Flying at the ends of the earth. A pilot’s journal‘.

Having read the book I can tell you that it’s a great collection of aviation tales and helicopter adventures. Aswell as being an entertaining read there is also a lot in it for the professional aviator in terms of safety culture, operational pressures and aviation management stressors.

RWS 19 – Height Velocity Diagram with Shawn Coyle

Shawn Coyle is an experienced helicopter test pilot with a passion for helping other pilots learn more about their profession.

Whether you walk away from a landing after an helicopter engine failure or not depends on many things but one good predictor is the Height Velocity(H/V) diagram.

The H/V diagram (also known as H/V curve and dead man’s curve) represents combinations of airspeeds and altitudes that have been determined for that helicopter type where it will be difficult or impossible to safely land the helicopter.

But how is the diagram or chart arrived at?

What are the conditions it is tested under?

In this episode of the Rotary Wing Show test pilot Shawn Coyle takes us in great detail through the diagram and the machinations that go into building one. Shawn’s experience ranges from civil and military operational flying to certification flight testing and training experimental test pilots.

An author of several well know helicopter books Shawn also on occasion acts as an expert witness and on crash investigations.

After listening to this episode you will have a much greater understanding of how the H/V diagram is derived, what it means for your flying operations and probably a reluctance to let your hover height drift upwards.
