I've skipped it recently, but for a long time during recurrent training at my US Major, I'd ask for the double flameout in the sim after the normal training is completed.
This has been in various conditions, used to be LGA where the Instructor would flame out both while headed down Manhattan Island at low level at 350 kts, roll 90 degrees
between the World Trade Center Towers (The visuals were removed from the sims weeks after 9/11), turn left and deadstick on RW04 at LGA. Good energy management practice
even though some flight scenarios were suspect. Fun part was managing energy to a normal landing and coasting to a Gate.
It's tough learning the glide skills in most US or Europe busy sectors. Endless ATC commands for speed and altitude wipe out most brain work for descent planning.
I understand the limitations in attempting to practice such events, but those flying should try to manually gauge their energy to a field without the Flight Directors, ND Map displays and vertical path indicators.
Fly it like a sick J3 Cub. You never know when you might need the skill set. Tough to do in many airspace environments as well as long duty days with fatigue issues, but worth the try. (safely within your accepted ops limits of course)
