Then why aren’t huge gliders are used for transportation of people or goods by giving them height and altitude using other aircraft and then gliding. Wont it be cheap
It's the same reason why we don't use sail boats for the same purposes instead of motorised ships. Of course, I'm comparing apples to oranges but to transport huge weights with gliders, then the wings become very large and unpractical, among other challenges.
Depending on the aircraft it will have a "best glide speed", which is the best speed it can efficiently glide, slower or faster you lose more altitude.
Interestingly this speed can be modulated in new gliders with water ballast in wings. And you can expect speeds of about 120 km/h (75 mph; 65 kn) with 55:1 glide ratio
But realistically there is always some movement in the air so you might sink more (so you speed up to get out of it ASAP) or you can get lift from the air currents and then you can choose how to use that energy (speed up to keep altitude, keep the speed and get altitude or slow down to your minimum rate of sink speed to maximise the altitude gained)
But you need to be at a high altitude. Cutting off the engines and letting it glide will also cut off the air compressor that makes the air pressure inside the cabin comfortable or livable. It will also cut off the hydraulics to operate the ailerons, elevators, flaps, rudder, air brakes, etc., the critical component to control the plane. I know there's an auxilliary engine when it happens, but there's still a risk.
most of the world uses metric system for altitude but producers from USA mount a altimeter scaled in feets. because of that for example in poland, for a glider pilot you must easly convert thees two @@stevenstyles7602
Can i jump off the roof and land safely on the road ahead??
Yes
very good knowladge for me

No?? Gliders are extremely unrialeble on the best of days and towing them in the air requires a LOT of fuel and full throttle ny the tower

@@Joyplanesplus, you need to get them in the air first 😂
At what speed?
Maybe gravity...

Correct @@amirhasanbasic2193
If a commercial airliner pulled a glider, And let it loose to have "2 destinations". Would it be economical?
So many factors involved in if it would be economical or not but it's an interesting idea!
But you need to be at a high altitude. Cutting off the engines and letting it glide will also cut off the air compressor that makes the air pressure inside the cabin comfortable or livable.

@@jannadrielcervo7753 just put the engines to idle instead! 😂
Who uses meters for height?
Many places, but it doesn't make any difference for glide ratio

@@stevenstyles7602
96% of the world. Only the U.S uses feet
@@AdamHalvo
You need to do some research, it’s actually the opposite, most pilots and aircraft use Feet when flying.
