Limitations Flashcards
What should you do if a limitation is exceeded?
Tell the engineers
During a slinging operation, you realize that a transient over-torque will be required to get a certain piece off the ground. How long are you allowed to use a transient over-torque for in such circumstances?
It’s not allowed.
What are the transient over-torque limits?
110% for 5s (105% for 5s 206L)
The maximum allowable TOT for a power transient degC for ____ seconds
10
Are you allowed to start the engine or perform a 2 minute cool down with a boost pump breaker pulled?
No
What if a fuel boost pump fails?
Keep below 6000 ft. 10 gal unusable.
The Center of Gravity limits for the 206 are _______ Longitudinal ______ Lateral _______ Front Door(s) off
106-114.2, 3L 4R
Under what flight conditions shall the engine anti-ice be on?
Below 4.4C in visible moisture
What is the effect of switching the engine anti-ice on?
TOT increase, TQ decrease
What is the VNE with the torque set between 85-100%?
92 mph (80 kts)
Why should you not exceed VNE with forward doors removed?
Cyclic stick reversal (sort of)
What is the power on VNE, and by what does it reduce above 3000 ft?
> 3000 lbs: 140 mph - 8/1000 ft (122/7 kts)
<3000 lbs: 150 mph - 4/1000 ft (130/3.5 kts)
Why does the VNE reduce with height?
The air is thinner and you need a higher angle of attack
What is the power off VNE?
115 mph (100 kts)
What is the VNE with doors off?
Aft - 100 mph (87 kts)
Fwd - 80 mph (69 kts)
What is the MAUW?
3200 lbs
3350 lbs with modifications or an external load
3000 lbs with fixed floats
How many fuel boost pumps do you need above 6000 ft?
2
What are the rotor speeds, power on?
95-100% - up to 8000 ft
97-100% - above 8000 ft
What are the rotor speeds in autorotation?
90-107%
What is the maximum continuous NG RPM?
104%
What is the maximum transient NG RPM?
105% for 15s
What is the mamximum operating altitude?
20,000 ft up to 3000 lbs
13,500 ft above 3000 lbs
What is the minimum fuel pump pressure?

What are the fuel pressure limits?
4-30 psi
What is the height of the avoid curve?
400 ft
Up to what height can you start the engine?
12,000 ft
When must anti-ice be used?
For flight in visible moisture below 4.4C
What is the maximum permissible load which can be applied to the main rotor blade tips when securing them after a flight?
100 lbs
What is the maximum continuous torque?
85%
What is the maximum cargo hook loading?
1500 lbs
