       LAND AS SOON AS PRACTICABLE

Descent and approach at low rate of descent

Question 37

FILTER (yellow light)

Answer 37

NOTE: Certain conditions may cause “FILTER” to flicker
Corrective action should only be taken when Illumination is continuous

1. Monitor TOT for any significant rise, i.e. >20 C
2. Monitor engine conditions for any indications of degradation or compressor stall
3. If rise in TOT or engine performance is unacceptable Open bypass door by pressing
   “FILTER” switch “BYPASS” switch should illuminate and “FILTER” switch should extinguish indicating the bypass door is open and the pressure is back within normal
   range.

                    WARNING To prevent compressor erosion avoid (if possible) operation in dirty or dusty environment with the bypass door open

Question 38

BYPASS (yellow light)

Answer 38

If the flight or landing environment has significant dirt or debris, it is recommended that the bypass door be closed, provided no rotorcraft or engine limits will be exceeded.
With the bypass closed, the “BYPASS” will extinguish and the “FILTER” will potentially reappear under high engine power settings until the filter has been cleaned
