1C-130H-1-1 Flashcards
The normal takeoff configuration is:
1077 TIT or 19,600 In-lbs. (whichever occurs first)
A/C and pressurization (normal bleed) on
50% flaps
Which parameters are taken into consideration when determining TOF?
Torque
Airfield pressure altitude
OAT
TIT
Engine efficiency %
Takeoff and landing charts should be run using ___% of a headwind and ___% of a tailwind
50% of a headwind
150% of a tailwind
Gust factor increases will be applied to which speeds?
Rotation
Takeoff
Approach
Threshold
Touchdown
Increase applicable air speeds by the full gust increment, not to exceed ___ knots
10
Do you apply headwinds when computing the acceleration time check?
Yep, always
In which cases should a tailwind be applied to performance calculations?
In all cases
What is critical field length (CFL)?
The greater of the runway distances required to accelerate on all engines, experience a failure of the critical engine, then either continue to lift-off or stop. It is used during takeoff planning, together with climb-out data, to determine the max gross weight for a safe takeoff or climb-out
What is balanced CFL?
The distance required to continue is equal to the distance required to stop
(No nose wheel steering)
What is unbalanced CFL?
The accelerate-stop distance from the lesser of Vmcg or Vrot is greater than the accelerate go distance
(Computed using nose wheel steering)
If an engine failure occurs exactly at Vrot, expect a lateral deviation as much as __ feet before lift off, and further lateral deviation as much as __ feet after lift off
30 feet
55 feet
What is refusal speed?
It is based on the runway available, and is the maximum speed to which the airplane can accelerate at take-off power and then stop within the runway remaining
What is critical engine failure speed?
It is based on critical field length
For balanced CFL, it is the speed to which the airplane can accelerate, lose an engine, and then either continue to take-off or stop
For unbalanced CFL, it is the lesser of Vmcg or Vrot
(Two in reverse, one at ground idle, one windmilling, max braking)
What is Vmcg?
The minimum airspeed at which the airplane may lose an outboard engine during takeoff roll and still maintain directional control
Vmcg assumptions:
1 windmilling on NTS
Max power on all operating engines
Zero bleed (good for any bleed)
50% flaps with 3000 psi rudder boost
Max available rudder deflection
Max deviation of 30’
Wings level
What is Vmca?
The minimum speed at which at which lateral directional control can be maintained for a given airplane configuration
Vmca assumptions:
1 windmilling on NTS
Max power on all operating engines
Zero bleed (good for any bleed)
50% flaps
Max available rudder deflection
5 degrees of bank away from inop engine
Landing gear down
Vmca increases by how many knots with:
Wings level
5 degrees adverse bank @80K lbs.
5 degrees adverse bank @140K lbs.
11 KIAS
20 KIAS
37 KIAS
What is Vmca2?
The minimum speed at which the airplane can maintain lateral directional control with two inoperative engines on the same wing
Vmca2 assumptions:
2 feathered
All bleed off
Max power on both operating engines
Utility hydraulic system inoperative
Max available rudder deflection
5 degrees of bank away from the inop engines
Landing gear down
50% flaps
Vmca2 increases by how many knots with:
Wings level
5 degrees adverse bank @80K lbs.
5 degrees adverse bank @140K lbs.
14 KIAS
30 KIAS
41 KIAS
What is takeoff distance?
The total distance required to accelerate to takeoff speed, lift off, and climb to 50’
MFLMETO is based on:
50% flaps
Static, max power takeoff
Paved runway
Takeoff speed of 1.2X power-on stall
OCS of 1.3X power-on stall
Disregards Vmca and Vmcg
What is MFLMETO?
The length of runway required to accelerate to refusal speed, experience an engine failure, and stop or continue to 1.2X power-on stall in the runway available
Select a speed for acceleration check that does exceed:
Vr - 10 knots
Cruise ceiling VVI
300 fpm
Service ceiling VVI
100 fpm
Driftdown procedure
Maintain driftdown airspeed until 100 fpm
Maintain 100 fpm until reaching appropriate service ceiling
Penetration descent profile
Idle, clean, L/D Max to 20,000’
Constant 250 KIAS below 20,000’
Minimum threshold speed
106.5 KIAS
Minimum touchdown speed
97 KIAS
