What fuel level will cause the low fuel annunciator to illuminate?
Low fuel warnings on annunciator panel: ‘L LOW FUEL’ – illuminates when quantity in left tank less than 5 gallons for more than 60 seconds. ‘LOW FUEL R’ – illuminates when quantity in right tank less than 5 gallons for more than 60 seconds.
What does sump the fuel mean?
Sump. A low point in an aircraft fuel tank in which water and other contaminants can collect and be held until they can be drained out.

Does a 172 have differential ailerons?
Ailerons. I believe 172 ailerons are differential-Frise ailerons. But that certainly isn’t the reason an aircraft turns when only aileron inputs are used. The horizontal component of lift causes an aircraft to turn, not the rudder.
How do you calculate descent fuel per hour?
Multiply the thousands of feet you need to lose by 3. This will be how far out you want to start your descent. Then, divide your groundspeed by 2 and multiply by 10. This will be your required rate of descent for a 3 degree glide-slope.
Why is it necessary to drain fuel from the fuel sumps when should this be done?
Aircraft fuel tanks are constructed with sumps to trap water. Since it is practically impossible to drain all water from the tanks through the fuel lines, the fuel tank sumps should be regularly drained in order to remove all water from the system.
Is a fuel tank sump required?
(a) Each fuel tank must have a sump with an effective capacity, in the normal ground attitude, of not less than the greater of 0.10 percent of the tank capacity or one-sixteenth of a gallon unless operating limitations are established to ensure that the accumulation of water in service will not exceed the sump capacity …
What is the purpose of differential ailerons?
Ailerons are a primary flight control surface which control movement about the longitudinal axis of an aircraft. Differential ailerons function in the same manner as symmetrical ailerons except that the upward deflecting aileron is displaced a greater distance than is the downward deflecting aileron.
Do ailerons increase drag?
Unfortunately, as well as reducing adverse yaw, Frise ailerons will increase the overall drag of the aircraft much more than applying rudder correction. Therefore, they are less popular in aircraft where minimizing drag is important (e.g. in a glider).
