Air Craft Deviation

T-6A INSTRUMENT NAVIGATION

CHAPTER SIX

AIRCRAFT DEVIATION

Any time you see your aircraft more than 100 feet off the assigned altitude, 10 KIAS off the

assigned airspeed or 5 off the assigned heading, you shall advise the IP of the deviation and

direct a correction. Any deviations within the standards listed above are acceptable and should

not be addressed.

Student:

"You are 150 feet below altitude. Climb to 9000 feet."

WEATHER CHECK

Get the current ATIS/ASOS information approximately 100 NM of your destination. If the

ATIS is available on a VHF frequency, you may use the VHF radio to get it. Ask the IP to

monitor the UHF while you get ATIS on the VHF. After getting ATIS on the VHF, tell the IP

you are back on UHF. The IP will inform you of any changes from ATC. If ATIS is available

only on a UHF frequency, an option for getting ATIS is to ask ATC for their VHF frequency and

re-contact them on VHF. Once you have positive contact on VHF, the UHF is available to get

ATIS. As a last resort you may ask ATC for a frequency change. Along with your frequency

change request, advise ATC you will monitor guard and report back up. An example of this call

would be:

"Houston Center, KATT 603, request 2 minutes off frequency, monitor guard."

Once you have attained the current ATIS, change back to the ATC frequency and advise you are

back on frequency.

"Houston Center, KATT 603 is back on frequency."

The ATIS is updated approximately 5 - 10 minutes before the top of the hour or significant

weather changes dictate, so you may not hear anything if the Tower is updating the information.

If ATIS is not available or more detailed information is desired, an in-flight call to Metro

(PMSV), FSS, or ATC should be made. This call should be made prior to the frequency change

to your destination Approach Control. The sooner you learn of poor weather conditions, the

more divert options you will have. Once the student gets the ATIS, brief the IP. You do not

need to call your destination's Metro facility to obtain the weather. Any Metro or FSS station

can perform this function, so have all pertinent local Metro frequencies written down as part of

your preflight preparations. (Otherwise, you will have to consult the FIH.) Write the pertinent

weather information on your scratch pad and have it ready when you initiate the field brief.

Pertinent weather information should include:

The identification letter (Alpha, Bravo, etc.).

Cloud ceilings and layers.

Visibility.
