Who's flying today

This is where our community discusses almost anything! While we're mainly a Cambodia expat discussion forum and talk about expat life here, we debate about almost everything. Even if you're a tourist passing through Southeast Asia and want to connect with expatriates living and working in Cambodia, this is the first section of our site that you should check out. Our members start their own discussions or post links to other blogs and/or news articles they find interesting and want to chat about. So join in the fun and start new topics, or feel free to comment on anything our community members have already started! We also have some Khmer members here as well, but English is the main language used on CEO. You're welcome to have a look around, and if you decide you want to participate, you can become a part our international expat community by signing up for a free account.

Yep, jet engined aircraft glide just fine, size and weight has fuck all to do with it. It's a bit like saying big ship made of steel can't float due to size and weight. Depending upon the flying height at total engine loss, they can glide for potentially a long way. The pilot has to work out the glide ratio factoring in speed, wind, aircraft type and other factors and they deploy the "RAT" to replace the failed engines as a system power source.

will just ignore a couple of statements here. To keep it basic, on a jet you look at your altimeter, read altitude and multiply it by 3. This will give you the distance in nautical miles available after engine failure. Add ten miles and consider a quater of the wind, subtract or add.,

both, on turboprop and jet aircraft are turbine engines. Equally sensitive to adverse conditions. There are high and low bypass jet engines. If you can't "feather" the effn prop after failure you will loose a lot of glide distance available. Also remember, there are piston engine props, as well as the above mentioned turboprops. In an attempt to raise your confidence in my statement, I have flown them all and intend to continue doing so.

if u guys compare the airflow between the propeller and jet engine, airflow over prop plane are mostly diverted over its prop. where else for the jet engine all of the airflow are sucked into the engine, there fore in adverse weather i.e. volcano ashes, micro ice crystals and micro particles could adversely affect the jet engine.

who cant fly in fair weather? thats why prop plane are safer in adverse weather (another example NOAA flew ATR72 directly into hurricanes!!! for weather surveys), that being said jet engine is more efficient flying at FL300 and above, so jet plane encounter less weather and perceived to be safer (less turbulence)

:thumb: Cheers. I had an idea there was a sort of rule of thumb calculation involving the altitude that would indicate possible distance but really couldn't remember what it is.

This was the case I first came across relating to lengthy gliding. https://en.wikipedia.org/wiki/Air_Transat_Flight_236

It was Air Crash Investigations or Seconds From Disaster or Fuck Me, How Did They Not All Die? or some such programme I saw it on and the calculation was mentioned on it.
