9ES: New tow bar

The factory-provided tow bar was not exactly a masterpiece of engineering, easily slipped off the wheel, and finally broke.
The replacement is a strong generic one that grabs the nose wheel from both sides and can be nicely stowed in the front left baggage compartment when collapsed.

3WF: OAT / TAS / Wind / DALT

We’re planning on adding a newly released outside air temperature sensor to 3WF in early October which will provide the OAT, true airspeed and wind information to the G5 units as well as density altitude on the GTN (in the DALT / TAS / Winds utility).

Planned additions marked in orange

Note that you can already get these bits and pieces of information anytime upon request by entering the current OAT retrieved from the system instrument in the upper left of the cockpit into that utility, but having it displayed and updated at all times without those steps certainly is a useful convenience.

Sun reflector 1&1

There appears to be recurring confusion among some pilots about how to handle sun reflectors – here are a few guidelines that should be helpful:

  • We’d like the sun reflector installed on all sunny days to avoid UV & heat damage to cockpit and interior while the aircraft is parked.
    You will also likely appreciate the lack of heat as you open the cockpit on a hot and/or sunny day with the reflector put in place by the previous pilot.
  • In 3WF
    • The silver side is for the outside, the white part is for the inside
    • There are arrows on the inside portion that depict which side is up
    • If you make sure to slide it between window and defroster outlet knobs it will be nice and easy to install
    • When you fly, it is recommended to just fold it halfway and slide it behind the front seats (unless you have back seat passengers of course) for easy post-flight access:
  • In 9ES
    • There are stickers that mark both the inside and which way is up to help avoid confusion
    • These three reflectors are hand-cut (because no commercial version could be found) and are therefore not perfect. However, they do fit pretty well, and can be tucked against the window edges
    • When not in use, these reflectors should be stowed in the area behind the back seats

Thank you for carefully using these provided means to help protect valuable shared aircraft equipment!

HIWAS being phased out

HIWAS – the hazardous in-flight WX service recordings available on VORs marked with a little inverted H on the sectional – is being phased out by the end of September 2019.

In light of the much richer and more effective WX updates availble with ADS-B In it makes a lot of sense to reallocate the resources necessary to maintain a legacy system fewer and pilots used (if they ever did).

Make use of the ADS-B In WX info streamed via Bluetooth to your EFB in both 3WF and 9ES (WX info is also available in 3WF directly on the GTNs, but not not 9ES’s G1000).

C172S Tachometer: Normal operating limit

This is a reminder that the normal engine speed operating limit (top of green arc, representing ~75% BHP) changes with altitude.

See also POH:

  • Section 4: ENROUTE CLIMB and CRUISE
  • Section 5: CRUISE PERFORMANCE / RANGE / ENDURANCE
For standard-day conditions, the top of the normal operating range is
2,500 RPM between sea level and 5,000′
2,600 RPM from 5,000′ – 10,000′
2,700 RPM above 10,000′

Soft-field operations

You may have seen AOPA’s Passport Challenge, handing out prizes for landing at grass strips – this is a gentle reminder of GFT’s Renter/Student Ops Manual regulation 5.6E, which states “Operations into any field other than paved surfaces (soft, gravel, sand, grass, etc) are prohibited unless prior approval is obtained from the Director of Operations, Chief or Assistant Chief Flight Instructor.

Thank you for helping keep our planes in the condition you wish to find them yourself!
