Flying Things to Know Quickly Flashcards
When to do FREDA checks?
Every 15 mins in flight.
What does FREDA stand for?
Fuel - on in good quantity
Radio - set to correct Freq
Engine & Electrics - T’s & P’s, carb heat
Direction indicators - set to compass heading
Altimeter - set to correct QNH or QFE
What does BUMFICH stand for?
B - BRAKES-OFF / Pressure Checked
U - UNDERCARRIAGE-DOWN
M - MIXTURE-Fully Rich
F - FUEL-Pump ON, BOTH / Contents sufficient for G/A
I - INSTRUMENTS-Di Synchronized, Altimeter, T’s and P’s Checked
C - CARB HEAT-CHECK
H - HATCHES-Hatches, Doors and harnesses secure
When do we do BUMFICH checks?
On downwind.
What does HASELL stand for?
Height – 3000’ AGL Airframe – Clean Security – Loose Articles Engine – T’s and P’s, Carb Heat Location – ABCD Look Out – 2x90 degrees
When do we do HASELL checks?
Before doing aerobatic maneuvers, or stalls, spins.
Always use carb heat when ……… .
Descending

55 Knots 172m
59 Knots Archer
Climb speed is ……. Knots.
65 Knots 172
76 knots Vy archer

90 Knots
113 knots
Taxi checks?
Brakes - check both sides
Rudder - Check correct movement and steering.
Instruments - Check in turns D.I., Compass, Turn coordinator, Altitude Indicator. VOR, ADF Tracking.
Take off checks?
Clearances - Revived and understood.
Runway - Approach and departure routes clear Surface checked.
Line Up - Re-Check DI. with Runway heading & compass.
Engine Temp & Press, steady and within limits.
Airspeed - Increasing.
Go - around?
Throttle - Full power
Carb heat - set cold
Attitude - correct for Yaw
Flaps - Retract Drag Flap to 20 degrees and there after retract all the way in when safe speed and height reached.
Radio - Call ‘Going around’ and obtain further ATC instruction.
Factors effecting stall speed: Weight?
The stall speed varies with the square root of lift. Aircraft = 2000lbs stall speed = 50Knots 2400lbs (20% increase) = 1.2 Square root of 1.2 is 1.1 Stall speed is 50Kts x 1.1 = 55Kts.
Factors effecting stall speed: Load Factor?
LEARN
Increases by the square root of the load factor
Equation for Lift?
L = (1/2) d v2 s CL L = Lift, which must equal the airplane's weight in pounds d = density of the air. This will change due to altitude. These values can be found in a I.C.A.O. Standard Atmosphere Table. v = velocity of an aircraft expressed in feet per second s = the wing area of an aircraft in square feet CL = Coefficient of lift , which is determined by the type of airfoil and angle of attack.
What is the increase in stall speed on each of these banked turns?
30
45
60
Stall speed increase:
30 - 8%
45 - 18%
60 - 40%
Throttle control when Taxing?
1700 RPM to get moving. Once at a jogging speed reduce to 1000RPM.
Always idle when ……… .
slowing down and before taxi.
First thing to do when taxi?
Check brakes.
Before a turn always …….. .
Lift wing and Look into turn.
