Circuits Flashcards
State the parameters that you should achieve to join through initial for a slow speed join.
1000-2000ft QFE
350kts
Approx. 80% RPM.
State your actions between initial and downwind for a slow speed join.
Make the initial radio calls.
Identify all other cct traffic.
Consider the effect of wind on the cct.
Arrive on the deadside at 1000ft QFE (accept speed given by approx 80% RPM).
Abeam the landing threshold select airbrake out.
Initiate the upwind turn once at approx. 230kts.
Select airbrake in to achieve 190kts at the start of the downwind leg.
Place acceleration markers on the HUD horizon.
How should you assess the normal circuit spacing when downwind?
The wingtip should almost run down the nearside edge of the runway.
State the parameters you should start the downwind leg at following a slow speed join.
190kts
1000ft
Acceleration bars on the HUD horizon.
You will need to adjust the timing of your Approach Checks to achieve the correct AOA at the end of the downwind leg.
What AOA are you aiming for at the end of the downwind leg?
5AOA
When should you cross check speed against AOA in the cct?
What AOA and speed are you looking to cross check at these points?
At the end of the downwind leg and on final on your first cct.
Downwind (gear down, 1/2 flap): You are checking that 5AOA corresponds to roughly 160kts +-10kts.
Final (gear down, full flap): 5 AOA should correspond to approx. 130kts.
If there appears to be a deviation between AOA and speed in the cct, what calculation can be made to work out the threshold speed (assuming SCN 7 and full flap)?
Threshold Speed = 118kts + 1kt per 100kg of fuel remaining.
When should you tip in for the final turn for a normal cct, assuming a 10kt headwind?
How should you adjust this for a stronger headwind?
How should you adjust it for a weaker headwind/ nil wind day?
Two seconds after you see the piano key diagonal reference point.
Stronger headwind: Turn at or even before the piano key diagonal reference point.
Weaker headwind: Extend the time after the piano key diagonal reference point.
State how to tip into the Final Turn during a normal cct.
Roll to approx. 45 degrees AoB.
Select 7 degrees ND.
Select Down flap.
Pull to achieve the runway centreline.
What AOA should you aim to achieve around the final turn?
Ideally 5AOA.
Not greater than 7.5AOA.
Approximately what height should you be at halfway around the final turn (for a 1000ft cct)?
650ft
What work cycle should you use in the final turn?
Runway - alpha - runway - alpha.
What should you do when the PAPIs change from 4 whites to 1 red and 3 whites in the final turn?
Bring the nose up to 3 degrees nose down to capture the three degree approach path.
What should you do if you roll out of the final turn and see 4 red PAPIs?
Go around.
What should you do if AOA increases to over 7.5 in the final turn or final approach?
Go around.
What parameters should you be aiming to achieve as you roll out of the final turn?
5AOA
Threshold 3 degrees ND in the HUD.
