Answer: ± 2% OF RUNWAY LENGTH.
Reference: OM Vol. 1, Section 1, Limitations
What is maximum temperature for aircraft operation?
Answer: ISA + 35ºC.
Reference: OM Vol. 1, Section 1, Limitations
What is the maximum takeoff and landing pressure altitude?
Answer: EMB-135LR and EMB-145LR: -1000 ft to 8000 ft.
EMB-145XR: -1000 ft to 10000 ft.
Reference: OM Vol. 1, Section 1, Limitations
What are the minimum and maximum fuel tank temperatures?
Answer: -40ºC to 52ºC.
Reference: OM Vol. 1, Section 1, Limitations
On a cold morning day, a GPU is not available so the APU is to be used, what is the minimum battery temperature for APU start?
Answer: The minimum battery temperature for APU start is -20ºC.
Reference: OM Vol. 1, Section 1, Limitations
What are the APU starter limits? At what percent rotor speed would the APU automatically shut down? How long can the APU operate in the amber range?
Answer: After 1st Attempt: 1 MINUTE OFF. After 2nd Attempt: 1 MINUTE OFF. After 3rd Attempt: 30 MINUTES OFF. The APU will be automatically shut down at 104% rotor speed. The APU EGT may exceed 680ºC up to 717ºC (Amber) for a maximum of 5 minutes.
Reference: OM Vol. 1, Section 1, Limitations
What is the maximum Electrical load on the APU above 30,000’?
Answer: 300 Amps above 30,000 ft..
Reference: OM Vol. 1, Section 1, Limitations
Assuming the oil temperature is -15°C, can engines be started?
Answer: Yes, the minimum oil temperature for starting is -40ºC.
Reference: OM Vol. 1, Section 1, Limitations
What is the maximum ITT during engine start?
Answer: 800ºC. Temperatures above 800ºC are permitted after 57% N2.
Reference: OM Vol. 1, Section 1, Limitations
If a crew has a ‘hung start’ during the 1st start attempt, what is the minimum time a crew must wait before another engine start can be attempted? What about engine start cycles 2 through 5?
Answer: 1 MINUTE OFF minimum after the 1st start attempt. The 2nd through 4th start attempt is 1 MINUTE ON, 1 MINUTE OFF. The 5th start attempt is 1 MINUTE ON, 5 MINUTES OFF.
Reference: OM Vol. 1, Section 1, Limitations
If a cold engine is started and the oil pressure increases to 120psi, what should the crew do? What if it was 115 psi?
Answer: 110 psi may be exceeded during starts if oil temperature is below 21ºC. The engine must remain at IDLE until the oil pressure is less than 110 psi.
Reference: OM Vol. 1, Section 1, Limitations
While taxiing out to the runway (using less than 88% N2) what is the acceptable oil pressure range
Answer: 34 psi to 110 psi (Green Range)
Reference: OM Vol. 1, Section 1, Limitations
What is the definition of a cold engine?
Answer: An engine is considered to be cold if it has been shut down for more than 90 minutes.
Reference: OM Vol.1, Section 1, Limitations
Assuming a cold engine, how long must the engine run to meet the engine warm-up limitations?
Answer: 4 minutes.
Reference: OM Vol. 1, Section 1, Limitations
Assuming a warm engine, how long must the engine run to meet the engine warm-up limitations?
Answer: 2 minutes.
Reference: OM Vol. 1, Section 1, Limitations
Assuming the engine was cold and the engine has run for 4 minutes, can the crew takeoff if the engine temperature is 38ºC?
Answer: No, to increase N2 above 83%, the engine oil temperature must be at 40ºC minimum. In lieu of this limit, it is acceptable to either to run the engine for at least 8 minutes or complete a static run-up to 88% N2, allow the engine to stabilize, check to ensure that the oil pressure is equal to or less than 83 psi.
Reference: OM Vol. 1, Section 1, Limitations
What is the min./max. SAT for takeoff?
Answer: -40/52 ºC
Reference: OM Vol. 1, Section 1, Limitations
What is the maximum tailwind component for T/O and Landing?
Answer: 10 KTS.
Reference: OM Vol. 1, Section 1, Limitations
What limitations are imposed on using the windshield wipers?
Answer: 170 KIAS. Do not operate on a dry windshield.
Reference: OM Vol. 1, Section 1, Limitations
What is VLO for retraction/extension? What is VLE?
Answer: VLO 200 KTS (retraction) 250 KTS (extension) VLE 250 KTS.
Reference: OM Vol. 1, Section 1, Limitations
On the takeoff roll, the oil pressure drops to 42 psi. Is this acceptable?
Answer: While this is an abnormal condition, operation between 34 and 48 psi (A1E) or between 34 and 50 psi (A1P & A1/3) is permitted during takeoff and go around phases of flight.
Reference: OM Vol. 1, Section 1, Limitations
On the takeoff roll the oil pressure increases to 112 psi. Is this acceptable? Would an increase to 118 psi be allowed? For how long?
Answer: Yes, 112 psi is permitted in all operational modes and is time limited to 5 minutes. Operation in the oil pressure amber range between 116 psi and 155 psi is permitted in all operational modes and is time limited to 2 minutes. However, total time above 110 psi may not exceed 5 minutes.
Reference: OM Vol. 1, Section 1, Limitations
