VISUAL CHECK OF LANDING GEAR DOWNLOCKS 
IF  Checking Nose Gear: 
OR  Verify the nose gear downlock indicator on the center pedestal is extended approximately . inch. * * * * 
IF  Checking Main Gear: 
Depressurize aircraft to below 1 psid. 
Note:  Periscope cover may be removed at maximum differential pressure, but considerable airflow and noise will result. Periscope is located left of center, opposite the third window aft of the second overwing exit. 
Raise carpet over periscope. 
Remove cover and dust cap. 
Turn on wheel well lights. (Switch is spring loaded and located adjacent to periscope.) 
Align periscope with index mark to view main gear downlock indicator (orange stripe on black background). 
Rotate periscope approximately 180° and align other index mark to view opposite gear downlock indicator. 
Note:  Periscope may be removed to clean mirrors.

ICE AND RAIN PROTECTION

AIRFOIL ICE PROTECTION INOPERATIVE

If unable to avoid icing conditions, use the following procedures:
- - - - - PRIOR TO FINAL APPROACH - - - - -
Add 5 knots to all minimum maneuvering speeds.  Do not extend flaps beyond 28. which may result in a decrease in airplane controllability.
- - - - - FOR FINAL APPROACH AND LANDING - - - - -
Flaps / Slats....................................................................................28 / EXT
Speed ........................................................VREF FOR 28 / EXT + 5 KNOTS

- - - - - IF GO-AROUND IS INITIATED - - - -
Flaps / Slats ..........................................................RETRACT TO 15 / EXT
Speed .........................................................................................MAINTAIN

Assure adequate airspeed because of possible ice accumulations.
Note:  Do not use 0/EXT through 13/EXT for maneuvering or go-around when wing icing is present or suspected due to possible adverse characteristics.
