So what's the best thing to do if you altimeter is showing your descending?,(reply>), @Cadde Also if you are upside down in a level flight than you should be able to feel it and correct it with out going into another turn,(reply>), @Cadde If you are in a cloud than read my previous comment but if you can not see through your canopy because of blood or anything else that will not go away in a minute or two than you have now choice but to use a parachute if you have one since I have not yet seen a glider that is able to land using only instruments,(reply>), @***** For gliders the best option if you know that the base of the cloud you are in is not near the ground and you are not speeding up, is to apply air breaks, keep up your speed and orient your self when you are bellow the cloud. Also if you are not in an electrically charged cloud the compass which all gliders must have will continue to work so you can judge your rate of turn based on that.,(reply>), @Somillian At the three gliding clubs that I was at, none of their gliders had an artificial horizon. Also most new gliders are designed to keep you in a turn with minimal effort meaning that for those gliders centering the control stick in these gliders will most likely result in nothing happening. And lastly it the law in the countries where I fly that glider pilots always have to see the ground and anything is a 3 mile radius meaning that if you know your surroundings you should be able to orient your self by the ground.,(reply>), @***** check your attitude gauge and/or turn coordinator. They both tell you where you're turning, and how fast. If they fail, you can then count on the magnetic compass, that shouldn't turn if you're in leveled flight.
