This is a very big issue. The problem is that you may have a good layover but still suffer from sleep deprivation. If you have to sleep during the day you will fight noise from housekeepers, other daytime people and just plain sunlight. At night you fight other flight crews getting up at 0400 and slaming doors as they leave their rooms. Then you also fight having to put up with the room party down the hall next door or kids running up and down the hall. Then just when you are really just starting to sleep the phone rings from a crewmember wanting to get something to eat, or the front desk telling you a fax has just arrived, or your wife calling to say the dog is lost. The list goes on and on, so how do you get enought sleep to be able to command an aircraft.
First I remind myself that I have 174+ people depending on my skill and my body to drive the jet safely. Reconize that my fellow crewmembers and struggling with the same problems, so they may be in the same shape that I am. Without sleep we will make a lot of mistakes and one of them could kill all of us. Mistakes mean trips to the FAA and the chief pilot office which causes additional stress, we don't want any of that. The worse factor is that lack of sleep usually doesn't catch you the next day but a couple of days later. Here are some rules that I follow to try and coup with the problems on the road. It doesn't mean that I follow them all the time, but when I do it makes all the diffrence.
1) Don't drink unless you have more than a 24 hour layover. For me usually if I drink even 1 beer or glass of wine I wake up after 3 hard hours of sleep and can't get back to sleep. I miss my REM sleep which is very important.
2)I take the phone in the room off the hook, if there is an emergency someone can bang on the door and wake me up.
3)I use a mechanical alarm in addition to all other alarms availiable-cell phone, beeper, in case of power failure.
4)I try to scedule 8 hours in my bed.
5)From experience I know that 8 hours is good sleep, 5 hours is sufficent sleep, with 3 hours of sleep I can do my job for one 16 hour period, but I need a long layover the next day.
6)Use earplugs and if I am sleeping during the day a "sleep mask."
7)I never use a chemical sleeping pill but I will use meletonane or St. Johns Wart to relax my brain.
8)Drink a lot of water, I sleep with a water jug right next to me, especially in the winter. I try to crack a window to keep fresh air in the room.
9)Pack everything the night before, including ironing my shirts.
10)Get up with good soothing music to get me in a good mood.
11)Always have a goal to be downstairs 15 minutes before show time to reduce stress.
12) I have found that the night I get excellent sleep I am more prone to errors, especially early in the morning, my body just does't want to wak up. When I have a lot of sleep I am very alert at the end of a long duty day then when I don't get enough sleep.
FAR121 Supplemental has no duty time restriction, only flight time, the company can fly you till you drop. JAR's are a lot more restrictive but more realistic and safer.
13)Last if you are being bothered by external noise call the front desk pack up your stuff and change rooms, better to do that than toss and turn all night wishing that things would quiet down.
