Review - Inadvertent Encounter with Freezing Rain

Procedures for Encounter with Freezing Rain

During this time of year, if you are a pilot in the Northern Hemisphere there is a possibility that you will fly into freezing rain. So we thought that now would be a good time for us Caravan Pilots to review procedures in the icing environment.

Please remember that the procedures found below are for the Cessna Model 208B (675 SHP) and no others. If you are flying a different model Caravan, please review your aircraft's FAA approved Abbreviated Checklist or Airplane Flight Manual for that specific model. 

Cessna's procedures for Inadvertent encounter with freezing rain or freezing drizzle:

Enroute

1.  Power - INCREASE to takeoff power (not to exceed 805 degrees ITT or 101.6% Ng).
2.  Airspeed - MAINTAIN 120 KIAS or greater (110 KIAS if climbing to exit icing).
3.  De-Ice boots - CYCLE to obtain best possible clearing.
4.  ATC - NOTIFY and request priority handling to exit condition.

Approach

1.  Approach - PLAN straight in approach if possible.
2.  ATC - NOTIFY and request priority handling to exit condition.
3.  Power - INCREASE to hold airspeed and glidepath (not to exceed 805 degrees ITT or 101.6% Ng).
4.  Airspeed - 120 KIAS (or greater).
5.  Flaps 10 degrees
6.  Airspeed - Maintain 120 KIAS if possible (minimum speed for flight in icing with 10 degrees flaps of 105 KIAS)

Minimum Speed in Icing Conditions (for all phases of flight including approach, except take-off and landing):

• Flaps Up: 120 KIAS
• Flaps 10: 105 KIAS
• Flaps 20: 95 KIAS

When climbing to exit icing conditions the following airspeeds may be used only for the duration of the climb to exit operation: (Maneuvering should be limited to 30 degrees of bank)

• Flaps Up: 110 KIAS
• Flaps 10: 95 KIAS

Landing

1. Recommended airspeed with ice on the airplane:

• Flaps 10: 120 KIAS

2. If 120 KIAS can not be maintained or other airfield constraints dictate use of other flaps or speeds, the following speeds can be used at the discretion of the pilot.

• Flaps Up: 110 - 120 KIAS
• Flaps 10: 105 - 110 KIAS
• Flaps 20: 95 - 100 KIAS

If you are a Caravan pilot, I highly recommend that you complete some of Cessna's E-Learning courses on this topic. Courses such as "Caravan Cold Weather Ops" and "Caravan Vodcast Ground Icing Conditions". There are many other interesting courses available, most of which are free and are all available at cessnaelearning.com.

Review - Engine Failure Immediately After Takeoff - C208B (675 SHP)

Review

Engine Failure Immediately After Takeoff

C208B (675 SHP)

The Caravan photographed above experienced an engine failure. It can happen to any airplane at anytime. I thought that today would be as good a day as any to review the Emergency Procedures for Engine Failure Immediately After Takeoff  for Cessna Model 208B (675 SHP). 

Us as pilots know, the worst time to experience an engine failure is during the takeoff phase of flight. This situation is also when pilots can have the least amount of time to react and usually seem to make the worst decisions. Including making the ill-advised decision to turn back towards the airport when they are too low to the ground. Forgetting simple Private Pilot 101 lessons of Aerodynamic Forces in Flight Maneuvers. Their fear induced large bank angle, to get them back to the airport, results in a large reduction in airspeed further resulting in a stall and crash.

Another reason that I would like to review this emergency procedure is because as a Skydive Pilot I realize that at this time of year there are a lot of new Caravan Pilots. Skydivers jump year round in most parts of the world, however a considerably larger amount of skydiving is done during the Spring and Summer months. A new season usually equals new Caravan pilots. As you might have read in some of my past articles, most of the Jump Pilot hiring is done during the month of April (in the Northern Hemisphere) and that is done to get them ready for the busy Summer months.

Please remember that these Emergency Procedures found below are for the Cessna Model 208B (675 SHP) and no others. If you are flying a different model Caravan, please review your aircraft's FAA approved Abbreviated Checklist or Airplane Flight Manual for that specific model.

As stated in the Pilots' Abbreviated Checklist published by Cessna, here are the procedures for:  

Engine Failure Immediately After Takeoff 

1.  Airspeed - 85 KIAS with 20 DEGREES FLAPS
2.  Propeller - FEATHER
3.  Wing Flaps - FULL DOWN
4.  Fuel Condition Lever - CUTOFF
5.  Fuel Shutoff - OFF (pull out)
6.  Fuel Tank Selectors - OFF (warning horn will sound)
7.  Battery - OFF    

If you have finished the above procedures and have double checked them all and you still have altitude (time) you should proceed with the Emergency Landing Without Engine Power procedures found in your aircraft's FAA approved Abbreviated Checklist or Airplane Flight Manual.

My fellow Caravan Pilots, please remember to Review Often and Fly Safe so that you can continue to Have Fun!
