In Flight Emergencies

Question 1

ENGINE FAILURE DURING FLIGHT

Answer 1

1. ZOOM/GLIDE – 125 KNOTS (MINIMUM)
2. PCL – OFF
3. INTERCEPT ELP
4. Airstart - Attempt if warranted
5. FIREWALL SHUTOFF handle - Pull
6. Execute Forced Landing or Eject

Question 2

Initial Indications on ENGINE FAILURE IN FLIGHT

Answer 2

-Engine failure/flameout: loss of power and airspeed (rapid decay N1, torque, ITT and prop towards feather due to loss oil Px)

Question 3

If N1 is reading 0% could the engine still be rotating?

Answer 3

Yes, if below 8% the N1 could indicate 0%

Question 4

What annunciators will illuminate with Engine Failure?

Answer 4

• GOOF lights
• GEN, FUEL PX, OIL PX, OBOGS FAIL
• could also have PMU FAIL and CKPT ALT

Question 5

Initial reaction to engine failure at low altitude

Answer 5

trade excess airspeed for altitude (above 150 KIAS 2G pullup 20 NH, 10 knots per 100’)

Question 6

Indications that warrant an Airstart

Answer 6

-Oil pressure will indicate around 4 PSI

Question 7

-Airstart

Answer 7

• PMU norm, PMU off and Immediate Airstart (PMU norm)

Question 8

-Airstart perimeters

Answer 8

• Airstarts may be attempted at any altitude and airspeed, although airstarts have only been demonstrated at 20,000 feet MSL and below
• If the airstart is successful, useful power will be available after 40 seconds from starter engagement.

Question 9

Depending on airspeed, N1 will indicate _____ within
approximately _____ seconds, even though the gas generator core may not have seized. N1 does not indicate speeds below _____.

Answer 9

0%; 5; 8%

Question 10

Zoom results with an engine still producing a usable torque (_____) will be _______________________ feet higher in altitude gained.

Answer 10

> 6%; several hundred to several thousand

Question 11

Zoom capability at 200 knots will vary from ____ to _____ feet of altitude gained.

Answer 11

600; 900

Question 12

Zoom capability at 250 knots will vary from _______ to ______ feet of altitude gained.

Answer 12

1170;1550

Question 13

The zoom to eject procedure will gain an additional _____ feet of altitude

Answer 13

200

Question 14

At engine flameout, the

engine oil pressure indicator may display oil pressures up to ____ psi with an N1 of 0%.

Answer 14

4

Question 15

If an airstart is successful, useful power will be available how long after starter engagement?

Answer 15

40 seconds

Question 16

The extra drag during airstart attempts will cause a greater

descent rate than _________ feet/minute

Answer 16

1350 to 1500 (clean glide with feathered prop)
