Prefect Limits FRC V2

Question 1

State the temperature limits.

Answer 1

Max Ground OAT = 38 degrees

Max OAT = ISA + 23 degrees

Min OAT = -54 degrees

Min OAT (reduced power setting) = ISA - 15 degrees

< 4 degrees, turn on P/S heat, comp intake and use FSII in fuel.

Question 2

Answer 2

Max opening speed = 110 KIAS

Max speed with canopy open = 120 KIAS

Question 3

Flap Limitations

Answer 3

With T/O flap extended = 151 KIAS

Beyond T/O flap = 114 KIAS

Question 4

Fuel Limitations

Answer 4

Total Capacity = 282.7kg

LH collector tank = 16.8kg

LH unusable = 6.3kg

RH unusable = 1.4kg

Max asymmetry = 45.3kg

Max per tank during aeros = 115kg

Max fuel pressure = 25psi
Min fuel pressure = 12psi

Question 5

Torque Limitations

Answer 5

Max Continuous Torque = 92%

Max T/O Torque (5 mins cumulative per flight) = 111%

Max transient (10 sec) torque = 115%

Question 6

N1 Limits (Gas generator RPM)

Answer 6

Max continuous = 105%

Max transient (15 sec) = 106%

Question 7

Severe Turbulence Airspeed Range

Answer 7

140-180 KIAS

Question 8

AuM Limitations

Answer 8

Max takeoff / landing = 1515kg

Max aerobatics = 1440kg

Max ZFW = 1370kg

Min flying = 1170kg

Max baggage compartment = 50kg

Question 9

V-Speeds

Answer 9

Vmo | Max operating speed = 238 KIAS

Mmo | Max operating mach = 0.45mn

Vo Aero | Max manoeuvre speed < 1440kg AuM = 164 KIAS

Vo Utility | Max manoeuvre speed (1440-1515kg AuM) = 143 KIAS

Question 10

Cross wind limits

Answer 10

Takeoff and landing = 25kts

Brakes off takeoff = 20kts

Flaps up beyond = 20kts

Question 11

G-Limits

Answer 11

Max Aero = 6g

Max utility = 4.4g

Max flaps down = 3.8g

Min flaps down = 0g

Max utility neg = -1.7g

Max aero neg = -4g

Question 12

Beta and Reverse Thrust

Answer 12

Reverse thrust to be used within 40-80kts on landing

Power lever must not be retarded below FI whilst airborne.

Question 13

Beta and Reverse Thrust

Answer 13

Reverse thrust to be used within 40-80kts on landing

Power lever must not be retarded below FI whilst airborne.

Question 14

Cross wind limits

Answer 14

Takeoff and landing = 25kts

Brakes off takeoff = 20kts

Flaps up beyond = 20kts

Question 15

G-Limits

Answer 15

Max Aero = 6g

Max utility = 4.4g

Max flaps down = 3.8g

Min flaps down = 0g

Max utility neg = -1.7g

Max aero neg = -4g

Question 16

N2 (Prop RPM) Limits

Answer 16

Max Transient (15 sec above 2132 N2) = 2233 N2

Max continuous = 2132 N2

Max static ground N2 w/ x-wind >10 kts = 1850 N2

N2 AVOID range = 1523 - 1786 RPM (no more than one second - cumulative time in avoid range must be recorded in engine logbook)

Question 17

Oil Pressure

Answer 17

<85% N1
Min 50psi / Min Beta 35psi

85%-94% N1
Min 90psi / Min Beta 75psi

> 94% N1
Min 120psi / Min Beta 105psi

Max = 130psi

Max transient (cold wx start) = 150psi

Min oil pressures decrease at 1psi per 1000ft above 5000ft pressure Alt to a max reduction of 20psi.

Question 18

Oil Temperatures

Answer 18

Max at TRQ <40% = 107 degrees

Max transient (5 min) at TRQ at or above 40% = 107 degrees

Max at TRQ at or above 40% = 82 degrees

Min Temp = 0 degrees

Min before start = -40 degrees

Question 19

Landing Gear Speeds

Answer 19

Vloe | Max speed landing gear operate extend - 182 kts

Vle | Max speed landing gear extended - 182 kts

Vlor | Max speed landing gear operate retract - 137 kts

Question 20

TOT Limits

Answer 20

Turbine Outlet Temperature (TOT)

Max engine start (10 secs over 810) = 927 degrees

Max transient (6 secs over 810) = 899 degrees

Max takeoff (5 min t/o cumulative) = 810 degrees

Max continuous = 752 degrees

Question 21

Engine Start Limits

Answer 21

Battery voltage required = 24V

30 sec Max use of starter per start attempt

3 attempts (1 min cooldown between each). If unsuccessful on 3rd attempt, wait 30 mins.

Question 22

Engine Start Limits

Answer 22

Battery voltage required = 24V

30 sec Max use of starter per start attempt

3 attempts (1 min cooldown between each). If unsuccessful on 3rd attempt, wait 30 mins.

Question 23
