Oral Limits Flashcards
(27 cards)
- Whatis the minimum flight crew?
2 PILOTS.
- What is maximum temperature for aircraft operation?
ISA + 35°C.
- What is the maximum takeoff and landing pressure altitude?
EMB-135ER/LR and EMB-145EP/LR: -1000 ft to 8000 ft. OM Vol. 1, Section 1, Limitations
- What are the minimum and maximum fuel tank temperatures?
-40°C to 52°C.
- On acold morning day, the airplane power is established. If the APU is to be ‘used, what is the minimum battery temperature for APU start?
The minimum battery temperature for APU start is -20°C.
- 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?
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 680°C up to 717°C (Amber) for a maximum of 5 minutes.
- When descending into an airport, what is the maximum flap extension altitude?
Maximum Altitude for Flap Extension 20,000 FT.
- What are the maximum flap extension speeds for flaps 9°, 18°, 22°, 45°? What if operating above 10, 000’ MSL?
9° 250 KIAS. 18° 200 KIAS 22° 200 KIAS 45° 145 KIAS
- While on an approach what are the minimum disengagement heights?
Minimum During Visual Approach 200 FT. AGL.! Minimum During CAT | ILS Approach 200 FT. AGL. Minimum During Non-Precision BEFORE LEAVING! Approach MDA
- When landing below what temperature would a maintenance inspection be required?
In the event of a landing below -40°C, the airplane may not takeoff without a maintenance inspection.
- Rev. 4 1/15/2015 The crew usually can let the aircraft a operations. If there was a malfunction became necessary, utomatically handle the anti-ice and manual anti-icing operations what would be the minimum and maximum temperatures limits be?
Minimum Temperature for Manual Anti-ice Operation -409°C. Maximum Temperature for Manual Anti-ice Operation 10°C.
0.63M, WHICHEVER IS LOWER. Reference: OM Vol. 1, Section 1, Limitations What is the min./max. SAT at FL370?
-65°C/-21.5°C.
- How long can the aircraft remain in the takeoff thrust setting? What is the maximum N1 value?
Takeoff thrust is time limited to 5 minutes. 100% N1.
2.5 IPS during takeoff?
May be exceeded up to (but not including) 2.5 IPS for 5 minutes during the takeoff or go-around phases of flight.
- Assuming the engine was cold and the engine has run for 4 minutes, can the crew takeoff if the engine temperature is 38°C?
No, to increase N2 above 83%, the engine oil temperature must be at 40°C 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.
- What is the min./max. SAT for takeoff?
-40/52 °C
- What is the maximum tailwind?
10 KTS.
- What limitations are imposed on using the windshield wipers?
170 KIAS. Do not operate on a dry windshield.
- What is VLO for retraction/extension? What is VLE?
VLO 200 KTS (retraction) 250 KTS (extension) VLE 250 KTS.
- On the takeoff roll the oil pressure drops to 42 psi. Is this acceptable?
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.
- Oni the takeoff roll the oil pressure increases to 112 psi. Is this acceptable? Would an increase to 118 psi be allowed? For how long?
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.
- What is the maximum ITT for engine start?
800°C.
- If a crew has a ‘hung start’ during the 1st start attempt what is the minimum time a crew has to wait before another engine start can be attempted? What about engine start cycles 2 through 5?
1 MINUTE OFF minimum after the 1st start attempt. The 2rd through 4th start attempt is 1 MINUTE ON, 1 MINUTE OFF. The 5th start attempt is 1 MINUTE ON, 5 MINUTES OFF.
- If a cold engine is started and the oil pressure spikes (increases) to 120 psi? What should the crew do? What if it was 115 psi?
110 psi may be exceeded during starts if oil temperature is below 21°C. The engine must remain at IDLE until the oil pressure is less than 110 psi.
