EKQ Flashcards
How many safety pins should be fitted in each cockpit when you check the aircraft before flight?
2
Where are the CFS pins stowed, and what procedure should be adopted?
CFS pin stowage box (rear cockpit).
Should be closed and latched after each opening.
Below what battery voltage should an internal start not be attempted?
23.5V
If, during the initial checks, the battery voltage is less than 22V, what should you do?
Bat Off, declare the aircraft U/S and return to ops
Describe the AUX BAT test sequence and pass/fail criteria.
Hold test for 5 seconds, one second for each cell in the Aux Bat. To pass the light must remain on for all 5 seconds, indicating that all cells are serviceable.
How do you know that Ext Pwr has been connected to the aircraft?
Visually watch the ground crew plug in the GPU and check the voltage to confirm it increases to 24-29.5V.
What must be disconnected before engaging the GEN after engine start?
GPU
How would you know if the aircraft safety interlocks are in place to ensure a safe start sequence?
ST READY caption is illuminated
What is the maximum permitted ITT during a start cycle and for how long is that temperature allowed?
1000°C, max 5 seconds between 871 and 1000°C.
List 6 reasons why you would manually abort an engine start?
No rise of ITT within 10 seconds of fuel flow indication (no start).
ITT likely to exceed 1000°C (hot start).
ITT likely to remain between 871 and 1000°C for > 5 secs.
Normal N1 increase is halted (hung start).
BATT BUS warning caption during start sequence.
Throttle is moved or ST READY extinguishes during start sequence.
PMU FAIL or PMU STATUS captions during start sequence.
Hydraulic pressure remains at zero during start sequence.
What is the maximum permitted IOAT for an engine start?
80°C
How many start/dry crank cycles are permitted and what is the cooling period required?
4 cycles
Each cycle length no more than 20 sec
Cooling period is:
1 - 30 sec
2 - 2 mins
3 - 5 mins
4 - 30 mins
What is the maximum permitted take-off mass?
6900lbs
What is the maximum wind speed for opening/closing the canopy?
40kts
What is the maximum tailwind for take-off and landing?
10kts
What is the maximum crosswind for take-off and landing (aircraft limit)?
25kts
What is the IAS/Mach No. limit for a clean aircraft?
316kts/0.67M
What is the maximum speed for flap extension?
150kts
What is the maximum speed for gear extension?
150kts
What are the minimum heights for practicing stalling and aerobatics?
Solo = 5000ft AGL
Dual - 4000ft AGL
What is the maximum fuel asymmetry for aerobatics?
50lbs
What are the symmetric and asymmetric ‘clean’ and ‘gear and/or flaps extended’ g limits?
Clean symmetric = -3.5 to +7g
Clean asymmetric = -1 to +4.7g
Gear/flap symmetric = 0 to +2g
Gear/flap asymmetric = 0 to +2g
What is the maximum permitted non-manoeuvring inverted flight time?
60 sec
After sustained negative g operation (> 15 sec), how long must elapse before further applications?
> 200lb per side = 30 sec
< 200lb per side = 60 sec
