General Knowledge Scenario Flashcards
You arrive at the gate in DEN to begin your three daytrip at 1200L. The current ATIS is KDEN 011753Z 35008KT 2SM–SN BKN040 0/0 A2992.
During the preflight the First Officer notes there is ice on the back side of the engine fan blades. How would you manage this situation?
Coordinate with ramp personnel to use warm/heated air. Since it is applied to the aircraft under pressure, Type I Fluid is unsuitable for direct application to certain areas such as the engine, windshield, probes, static ports, and APU inlet. Spraying deicing/anti-icing fluid into the engine intake is prohibited. Warm/heated air must be used to deice the engine inlet, fan blades, and spinner.

The Ops Agent informs the Captain that Ground Deicing/Anti-Icing Operations are in effect. Is the Captain required to have the aircraft deiced/anti-iced? Why?
No. If the aircraft is free of contamination and the Captain determines that it will remain so while on the ground, the Captain may decide the aircraft does not require deicing/anti-icing.

The crew determines deicing is required and estimates it will take 5 minutes to taxi from the deice/anti-ice pad to takeoff. DEN is using Clariant Safewing MP IV Launch type IV fluid. Both the One-Step and Two-Step methods are available. Which method should the crew use to deice/anti-ice the aircraft, using the HOTsapp?
Based off of the derived snow fall intensity of light snow the HOTs are:
•One-Step method –0:08-0:14
•Two-Step method –1:20-2:09
The One-Step method is a viable option. Holdover time starts at the beginning of the final fluid application. Completing the fluid application, remain checklist, and a 5 minute taxi would allow the aircraft to takeoff within the 14 minute upper limit of the One-Step method HOT.

When is a cabin check required?
A cabin check is required when the HOT is exceeded or any time heavy snow is present.

The Crew is developing a Shared Mental Model to perform engine run-ups for their NG aircraft. What engine run-up procedure is required in this situation?
NG –An engine run-up of 70% to establish stable operation (30 seconds recommended) is required in conjunction with the takeoff.
MAX –An engine run-up of 50% for 5 seconds is required within 5 minutes of or in conjunction with the takeoff.
A new ATIS is issued during pushback: KDEN 011833Z Special 35008KT 1SM -PLFZRABKN040 -1/-3. What is your allowance time using a Two Step Method, assuming the HOTs app is unavailable?
19 minutes
