TD 19 Flashcards
The first limit indicator (FLI) gives an analogue indication of the limiting parameter associated with the helicopter engine primary limitations for: _______. This indication is completed by the display of digital data for the three parameters. The dial scale of the _______ and does ___ represent a ____ value.
NOTE Even though the rotor is stopped it is possible that due to torque calibration tolerance, a digital torque value of up to ___ is indicated and the needle of first limit indicator is in “0” position. In that case __ corrective action is necessary.
N1 TOT and Torque, analogue display is arbitrary, not, percent,
3%, no
The airspeed tendency indicator gives the predicted airspeed after ____ if the acceleration remains constant.
NOTE As airspeed values below ____ are ____, no precise graduations are
shown below this figure.

Engine instruments – Monitor 3. Collective lever – Raise slowly If compressor stall returns: 4. Affected engine – Identify (TOT) 5. Single engine emergency shutdown – Perform 6. LAND AS SOON AS PRACTICABLE
LAND IMMEDIATELY
The urgency of landing is paramount. Primary considerations is to assure survival of the occupants. Landing in water, trees, or other area should be considered only as a last resort
LAND AS SOON AS POSSIBLE
Land without delay at the nearest adequate site (i .e. open field) at which a safe approach and landing can be made
LAND AS SOON AS PRACTICABLE
The landing site and duration of flight are at the discretion of the pilot. Extended flight beyond the nearest landing area where appropriate assistance can be expected is not recommended
SINGLE ENGINE EMERGENCY SHUTDOWN
- Twist grip (affected engine) - rotate slowly to idle, check indications, then to OFF
- Rotor speed - trim to maximum
Bleed air heating (if installed) will be shutdown automatically, however, depending on power margin of remaining engine, may be re-engaged as follows: - BLD HTG EMER/NORM SW - EMER
- BLD HTG Rheostat - ON
DOUBLE ENGINE EMERGENCY SHUTDOWN
ON GROUND
- Both twist grips - OFF
- Both FUEL PRIME PUMP sw - OFF
- BAT MSTR sw - OFF
IN FLIGHT
1. Both twist grips - OFF
If there is an indication that the engines are still running
2. Both EMER OFF sw - Press
