i had dual engine flameout in my last simu session....... As far as i remember, with drift down speed (around 125 IAS) the descent rate was around 800 ft/min (with feathered engines) .

Hi Christian Sounds like my last Dash sim. Dual flameout at night glide 35nm from FL230 to land in the dark. Good fun!! How many sims do you do a year there.We are in every3 months. What sort of distance plan do you have in the ATR we have a 2:1 based off altitude for the Dash. Seeya

I guess it means that for every 7 miles you go horizontally, you would loose 1 mile vertically. I may be wrong!! Francois

| From this sink rate and ktas you'd get a glide ratio of 15.8:1, this is also a L/D ratio. It seems reasonable. The 2015 paper 'Is "Green Dot" Always the Optimum Engines-Out Glide Speed on the Airbus A320 Aircraft' suggests 17:1 for the A320ceo, so for a regional airliner with higher AR 15.8:1 sounds a bit low. Still possible though. It's definitely higher than 7:1 |
